How to Write Topic Sentences | 4 Steps, Examples & Purpose

Published on July 21, 2022 by Shona McCombes . Revised on June 5, 2023.

Every paragraph in your paper needs a topic sentence . The topic sentence expresses what the paragraph is about. It should include two key things:

• The  topic of the paragraph
• The central point of the paragraph.

After the topic sentence, you expand on the point zwith evidence and examples.

To build a well-structured argument, you can also use your topic sentences to transition smoothly between paragraphs and show the connections between your points.

Table of contents

Writing strong topic sentences, topic sentences as transitions between paragraphs, topic sentences that introduce more than one paragraph, where does the topic sentence go, frequently asked questions about topic sentences.

Topic sentences aren’t the first or the last thing you write—you’ll develop them throughout the writing process. To make sure every topic sentence and paragraph serves your argument, follow these steps.

Step 1: Write a thesis statement

The first step to developing your topic sentences is to make sure you have a strong thesis statement . The thesis statement sums up the purpose and argument of the whole paper.

Thesis statement example

Food is an increasingly urgent environmental issue, and to reduce humans’ impact on the planet, it is necessary to change global patterns of food production and consumption.

Step 2: Make an essay outline and draft topic sentences

Next, you should make an outline of your essay’s structure , planning what you want to say in each paragraph and what evidence you’ll use.

At this stage, you can draft a topic sentence that sums up the main point you want to make in each paragraph. The topic sentences should be more specific than the thesis statement, but always clearly related to it.

Topic sentence example

Research has consistently shown that the meat industry has a significant environmental impact .

Step 3: Expand with evidence

The rest of the paragraph should flow logically from the topic sentence, expanding on the point with evidence, examples, or argumentation. This helps keep your paragraphs focused: everything you write should relate to the central idea expressed in the topic sentence.

In our example, you might mention specific research studies and statistics that support your point about the overall impact of the meat industry.

Step 4: Refine your topic sentences

Topic sentences usually start out as simple statements. But it’s important to revise them as you write, making sure they match the content of each paragraph.

A good topic sentence is specific enough to give a clear sense of what to expect from the paragraph, but general enough that it doesn’t give everything away. You can think of it like a signpost: it should tell the reader which direction your argument is going in.

To make your writing stronger and ensure the connections between your paragraphs are clear and logical, you can also use topic sentences to create smooth transitions. To improve sentence flow even more, you can also utilize the paraphrase tool .

As you write each topic sentence, ask yourself: how does this point relate to what you wrote in the preceding paragraph? It’s often helpful to use transition words in your topic sentences to show the connections between your ideas.

Emphasize and expand

If the paragraph goes into more detail or gives another example to make the same point, the topic sentence can use words that imply emphasis or similarity (for example, furthermore , indeed , in fact , also ).

Indeed , cattle farming alone is responsible for a large proportion of greenhouse gas emissions.

Summarize and anticipate

If the paragraph turns to a different aspect of the same subject, the topic sentence can briefly sum up the previous paragraph and anticipate the new information that will appear in this one.

While beef clearly has the most dramatic footprint, other animal products also have serious impacts in terms of emissions, water and land use.

Compare and contrast

If the paragraph makes a comparison or introduces contrasting information, the topic sentence can use words that highlight difference or conflict (for example, in contrast , however , yet , on the other hand ).

However , the environmental costs of dietary choices are not always clear-cut; in some cases, small-scale livestock farming is more sustainable than plant-based food production.

You can also imply contrast or complicate your argument by formulating the topic sentence as a question.

Is veganism the only solution, or are there more sustainable ways of producing meat and dairy?

Sometimes you can use a topic sentence to introduce several paragraphs at once.

All of the examples above address the environmental impact of meat-eating versus veganism. Together, they make up one coherent part of a larger argument, so the first paragraph could use a topic sentence to introduce the whole section.

In countries with high levels of meat consumption, a move towards plant-based diets is the most obvious route to making food more sustainable. Research has consistently shown that the meat industry has significant environmental impacts.

The topic sentence usually goes at the very start of a paragraph, but sometimes it can come later to indicate a change of direction in the paragraph’s argument.

Given this evidence of the meat industry’s impact on the planet, veganism seems like the only environmentally responsible option for consumers. However, the environmental costs of dietary choices are not always clear-cut; in some cases, small-scale livestock farming is more sustainable than plant-based food production.

In this example, the first sentence summarizes the main point that has been made so far. Then the topic sentence indicates that this paragraph will address evidence that complicates or contradicts that point.

In more advanced or creative forms of academic writing , you can play with the placement of topic sentences to build suspense and give your arguments more force. But if in doubt, to keep your research paper clear and focused, the easiest method is to place the topic sentence at the start of the paragraph.

A topic sentence is a sentence that expresses the main point of a paragraph . Everything else in the paragraph should relate to the topic sentence.

Topic sentences help keep your writing focused and guide the reader through your argument.

In an essay or paper , each paragraph should focus on a single idea. By stating the main idea in the topic sentence, you clarify what the paragraph is about for both yourself and your reader.

The topic sentence usually comes at the very start of the paragraph .

However, sometimes you might start with a transition sentence to summarize what was discussed in previous paragraphs, followed by the topic sentence that expresses the focus of the current paragraph.

Let’s say you’re writing a five-paragraph  essay about the environmental impacts of dietary choices. Here are three examples of topic sentences you could use for each of the three body paragraphs :

• Research has shown that the meat industry has severe environmental impacts.
• However, many plant-based foods are also produced in environmentally damaging ways.
• It’s important to consider not only what type of diet we eat, but where our food comes from and how it is produced.

Each of these sentences expresses one main idea – by listing them in order, we can see the overall structure of the essay at a glance. Each paragraph will expand on the topic sentence with relevant detail, evidence, and arguments.

How to Write a Topic Sentence (30+ Tips & Examples)

Writing the perfect topic sentence took me years to master.

After endless drafts, feedback sessions, and seeing what resonates with readers, I’ve distilled the ultimate guide to craft attention-grabbing, informative, and concise topic sentences.

Let’s dive into the essential tips for how to write a topic sentence.

What Is a Topic Sentence and Why Is It Important?

Table of Contents

A topic sentence introduces the main idea, usually appearing at the start of a paragraph.

It sets the tone for the entire paragraph by giving a glimpse of what’s coming. Think of it as a headline for each paragraph that keeps your writing clear and focused.

A strong topic sentence is important because:

• Grabs Attention: Captures the reader’s interest, encouraging them to keep reading.
• Guides Structure: Helps organize thoughts in a logical way.
• Provides Focus: Prevents rambling by clarifying the main point.

Types of Topic Sentences

Different types of topic sentences can fit various writing styles and purposes.

Understanding these types will help you select the best approach for your specific content.

• Declarative Statements: These are straightforward sentences that make a clear assertion. They introduce the main idea without any fluff or ambiguity. Example: “Water conservation is critical in regions prone to drought.”
• Interrogative Sentences: These topic sentences pose a question, encouraging readers to think critically and seek answers within the paragraph. Example: “How can sustainable practices help reduce waste in the fashion industry?”
• Complex Sentences: By combining independent and dependent clauses, these topic sentences present a nuanced main idea that prepares readers for a more detailed discussion. Example: “Although renewable energy sources are gaining popularity, fossil fuels still dominate the global energy sector.”
• Bridge Sentences: These link the preceding paragraph to the next, providing continuity and coherence in the overall structure. Example: “While electric vehicles offer a greener alternative to traditional cars, the infrastructure for widespread adoption remains lacking.”
• Contrasting Statements: These topic sentences highlight opposing viewpoints or circumstances, building intrigue and depth into the following paragraph. Example: “Despite the technological advancements in healthcare, access remains limited for underserved communities.”

My 30 Best Tips for Writing a Topic Sentence

Now let’s get into the main section of this guide — where you will learn all the best tips for writing a compelling topic sentence on any subject.

Tip #1: State the Main Idea Clearly

Make sure your topic sentence introduces the primary idea succinctly.

Avoid vague language or cluttered wording. Your reader should immediately understand the topic.

• Clear: “Recycling programs reduce landfill waste by promoting reusable packaging.”
• Unclear: “Programs for recycling can be a good thing because it’s important.”

Tip #2: Keep It Simple and Direct

A topic sentence should be straightforward. Avoid complex structures and over-complicated phrasing.

Shorter sentences work best.

• Simple: “Exercise improves mental health through endorphin production.”
• Complicated: “One can expect to experience benefits in their mental state with exercise due to the generation of endorphins.”

Tip #3: Link to the Previous Paragraph

Create a smooth flow by connecting ideas to the paragraph before.

Transition words like “similarly,” “however,” or “in contrast” help show relationships.

• Linked: “Similarly, the agricultural industry is also impacted by climate change.”
• Disjointed: “Farmers are struggling with erratic weather patterns.”

Tip #4: Avoid Announcing Your Intentions

Steer clear of sentences like “In this paragraph, I will discuss…” They sound amateurish and reduce reader engagement.

• Natural: “Effective communication skills are crucial for career advancement.”
• Announcing: “This paragraph will explain why communication skills are important.”

Tip #5: Vary Sentence Structure

Using the same structure repeatedly can bore readers.

Mix up your approach by experimenting with different forms like questions, facts, and lists.

• Varied: “How does cultural background influence consumer behavior?”
• Repetitive: “Consumer behavior is influenced by cultural background.”

Tip #6: Be Specific, Not General

A vague topic sentence leaves the reader confused. Instead, provide specific information to establish clarity and interest.

• Specific: “Remote work improves productivity by reducing commute times.”
• General: “Remote work is beneficial for many reasons.”

Tip #7: Reflect Your Argument’s Tone

Match your topic sentence with the tone of your argument. For serious discussions, avoid informal language.

• Formal: “The socioeconomic impact of urbanization requires comprehensive policy solutions.”
• Informal: “The effects of city living need some fixing.”

Tip #8: Include a Controlling Idea

The controlling idea limits the scope of the paragraph, ensuring the reader knows what to expect next.

• With Control: “Social media marketing increases brand visibility through targeted campaigns.”
• Without Control: “Social media is important.”

Tip #9: Use Active Voice

Active voice is more engaging and dynamic. It also provides clarity.

• Active: “New policies will reshape healthcare accessibility.”
• Passive: “Healthcare accessibility will be reshaped by new policies.”

Tip #10: Make It Unique

Avoid using overused phrases or predictable statements. Offer a fresh perspective to captivate your reader.

• Unique: “Biodegradable packaging is transforming the fast-food industry.”
• Cliché: “The fast-food industry is changing with new trends.”

Tip #11: Create Curiosity

Tease your reader by leaving questions unanswered. Encourage them to keep reading for more.

• Curious: “What are the unexpected benefits of rising inflation rates?”
• Blunt: “Rising inflation rates have some positive effects.”

Tip #12: Support Your Thesis

Your topic sentence should align with your overall thesis. It will give your argument more coherence.

• Aligned: “Reducing plastic waste aligns with our sustainability goals.”
• Unaligned: “Plastic recycling is controversial.”

Tip #13: Focus on One Point

Don’t overwhelm readers with multiple ideas in one topic sentence. Stick to one clear concept.

• One Point: “Artificial intelligence streamlines data analysis.”
• Too Broad: “Artificial intelligence changes marketing, finance, and data analysis.”

Tip #14: Use Key Terms From the Prompt (if applicable)

If you are responding to an assignment or specific topic prompt, make sure your topic sentence directly incorporates relevant keywords.

• Key Terms Included: “Global warming solutions must involve international cooperation.”
• Lacks Terms: “Solutions for the environment require cooperation.”

Tip #15: Offer Context

Provide some context in the topic sentence to frame the discussion, giving the reader essential background information.

With Context: “As urbanization accelerates, city infrastructure struggles to keep up.” Without Context: “City infrastructure is lagging.”

Tip #16: Incorporate Comparisons

Comparisons can clarify complex concepts and give readers a familiar reference.

• Comparison: “Just as the printing press revolutionized communication, the internet has transformed modern commerce.”
• No Comparison: “The internet has transformed modern commerce.”

Tip #17: Present Solutions

Offering a solution at the start engages readers who are seeking actionable advice.

• Solution: “Installing solar panels reduces energy bills while cutting carbon emissions.”
• Problem-Only: “High energy bills are a widespread issue.”

Tip #18: Address Common Misconceptions

Challenge preconceived notions to spark curiosity and highlight the importance of your argument.

• Challenging: “Despite common belief, vitamin supplements aren’t always beneficial.”
• Reinforcing: “Vitamin supplements have benefits.”

Tip #19: Use Emotional Appeals

Appeal to the reader’s emotions to deepen their connection to your writing.

• Emotional: “Volunteering at shelters uplifts communities and transforms lives.”
• Neutral: “Volunteering at shelters is helpful.”

Tip #20: Avoid Redundancy

Ensure your topic sentence adds new value. Avoid repeating points covered elsewhere.

• New Value: “Stronger copyright laws are crucial for protecting intellectual property.”
• Redundant: “Intellectual property needs stronger protection.”

Tip #21: Ask a Thought-Provoking Question

Pose a question that makes the reader stop and think. This engages them immediately.

• Provocative: “How will automation reshape the global workforce?”
• Plain: “Automation is changing the global workforce.”

Tip #22: Include an Action Verb

Action verbs add momentum and urgency to your topic sentence. They make your point more dynamic.

• Active Verb: “Investing in renewable energy fosters long-term economic growth.”
• Lacks Action: “Renewable energy investments are beneficial.”

Tip #23: Paint a Picture

Use descriptive language to help readers visualize your point.

• Descriptive: “Increased droughts have turned fertile farmlands into arid deserts.”
• Bland: “Droughts are affecting farmlands.”

Tip #24: Use Parallel Structure

Parallel structure involves repeating similar grammatical forms.

It makes your writing rhythmic and easy to follow.

• Parallel: “Tackling pollution requires reducing emissions, cleaning waterways, and limiting waste.”
• Non-Parallel: “Tackling pollution requires emission reductions, waterways cleaning, and limiting waste.”

Tip #25: Emphasize Urgency

Highlight the time-sensitive nature of your argument to create urgency.

• Urgent: “Immediate action is needed to prevent further deforestation.”
• Calm: “Deforestation is a concern.”

Tip #26: Highlight Contrasts

Contrasting different ideas helps to emphasize your point and draw clear distinctions.

• Contrast: “While technology creates new jobs, it also disrupts traditional industries.”
• No Contrast: “Technology affects the job market.”

Tip #27: Lead with a Statistic

Start with a compelling number to catch the reader’s attention and back up your argument.

• Statistic: “80% of small businesses struggle to comply with data privacy regulations.”
• General Statement: “Small businesses struggle with data privacy.”

Tip #28: Build on Existing Knowledge

Assume the reader has some background knowledge and expand on it.

• Builds On Knowledge: “With the rise of remote work, companies are rethinking their office spaces.”
• Basic Information: “Remote work is changing office spaces.”

Tip #29: Start with an Anecdote

A brief anecdote adds a human touch, creating an immediate connection with the reader.

• Anecdotal: “After years of burnout, Sarah switched to a part-time schedule to improve her work-life balance.”
• Abstract: “Work-life balance is important.”

Tip #30: Use an Engaging Metaphor

A metaphor can illuminate your argument in an unexpected way.

• Metaphor: “Effective teamwork is the glue that holds successful organizations together.”
• Literal: “Effective teamwork is important for organizations.”

Topic sentences and signposts make an essay's claims clear to a reader. Good essays contain both.  Topic sentences   reveal the main point of a paragraph. They show the relationship of each paragraph to the essay's thesis, telegraph the point of a paragraph, and tell your reader what to expect in the paragraph that follows. Topic sentences also establish their relevance right away, making clear why the points they're making are important to the essay's main ideas. They argue rather than report.  Signposts , as their name suggests, prepare the reader for a change in the argument's direction. They show how far the essay's argument has progressed vis-ˆ-vis the claims of the thesis. 

Topic sentences and signposts occupy a middle ground in the writing process. They are neither the first thing a writer needs to address (thesis and the broad strokes of an essay's structure are); nor are they the last (that's when you attend to sentence-level editing and polishing). Topic sentences and signposts deliver an essay's structure and meaning to a reader, so they are useful diagnostic tools to the writer—they let you know if your thesis is arguable—and essential guides to the reader

Forms of Topic Sentences

 Sometimes topic sentences are actually two or even three sentences long. If the first makes a claim, the second might reflect on that claim, explaining it further. Think of these sentences as asking and answering two critical questions: How does the phenomenon you're discussing operate? Why does it operate as it does?

There's no set formula for writing a topic sentence. Rather, you should work to vary the form your topic sentences take. Repeated too often, any method grows wearisome. Here are a few approaches.

Complex sentences.   Topic sentences at the beginning of a paragraph frequently combine with a transition from the previous paragraph. This might be done by writing a sentence that contains both subordinate and independent clauses, as in the example below.

 Although  Young Woman with a Water Pitcher  depicts an unknown, middle-class woman at an ordinary task, the image is more than "realistic"; the painter [Vermeer] has imposed his own order upon it to strengthen it. 

This sentence employs a useful principle of transitions: always move from old to new information.  The subordinate clause (from "although" to "task") recaps information from previous paragraphs; the independent clauses (starting with "the image" and "the painter") introduce the new information—a claim about how the image works ("more than Ôrealistic'") and why it works as it does (Vermeer "strengthens" the image by "imposing order"). 

Questions.   Questions, sometimes in pairs, also make good topic sentences (and signposts).  Consider the following: "Does the promise of stability justify this unchanging hierarchy?" We may fairly assume that the paragraph or section that follows will answer the question. Questions are by definition a form of inquiry, and thus demand an answer. Good essays strive for this forward momentum.

Bridge sentences.   Like questions, "bridge sentences" (the term is John Trimble's) make an excellent substitute for more formal topic sentences. Bridge sentences indicate both what came before and what comes next (they "bridge" paragraphs) without the formal trappings of multiple clauses: "But there is a clue to this puzzle." 

Pivots.   Topic sentences don't always appear at the beginning of a paragraph. When they come in the middle, they indicate that the paragraph will change direction, or "pivot." This strategy is particularly useful for dealing with counter-evidence: a paragraph starts out conceding a point or stating a fact ("Psychologist Sharon Hymer uses the term Ônarcissistic friendship' to describe the early stage of a friendship like the one between Celie and Shug"); after following up on this initial statement with evidence, it then reverses direction and establishes a claim ("Yet ... this narcissistic stage of Celie and Shug's relationship is merely a transitory one. Hymer herself concedes . . . "). The pivot always needs a signal, a word like "but," "yet," or "however," or a longer phrase or sentence that indicates an about-face. It often needs more than one sentence to make its point.

Signposts operate as topic sentences for whole sections in an essay. (In longer essays, sections often contain more than a single paragraph.) They inform a reader that the essay is taking a turn in its argument: delving into a related topic such as a counter-argument, stepping up its claims with a complication, or pausing to give essential historical or scholarly background. Because they reveal the architecture of the essay itself, signposts remind readers of what the essay's stakes are: what it's about, and why it's being written. 

Signposting can be accomplished in a sentence or two at the beginning of a paragraph or in whole paragraphs that serve as transitions between one part of the argument and the next. The following example comes from an essay examining how a painting by Monet,  The Gare Saint-Lazare: Arrival of a Train,  challenges Zola's declarations about Impressionist art. The student writer wonders whether Monet's Impressionism is really as devoted to avoiding "ideas" in favor of direct sense impressions as Zola's claims would seem to suggest. This is the start of the essay's third section:

It is evident in this painting that Monet found his Gare Saint-Lazare motif fascinating at the most fundamental level of the play of light as well as the loftiest level of social relevance.  Arrival of a Train  explores both extremes of expression. At the fundamental extreme, Monet satisfies the Impressionist objective of capturing the full-spectrum effects of light on a scene.

 The writer signposts this section in the first sentence, reminding readers of the stakes of the essay itself with the simultaneous references to sense impression ("play of light") and intellectual content ("social relevance"). The second sentence follows up on this idea, while the third serves as a topic sentence for the paragraph. The paragraph after that starts off with a topic sentence about the "cultural message" of the painting, something that the signposting sentence predicts by not only reminding readers of the essay's stakes but also, and quite clearly, indicating what the section itself will contain.

What is a Topic Sentence? (Definition, Examples, How to Use)

What is a topic sentence ? A topic sentence , the first sentence of a paragraph, presents the main concept discussed in the paragraph. It must contain sufficient information to support numerous examples and subtopics without being too broad to obscure the essay’s intended purpose. The remaining sentences in the paragraph will act as supporting statements, providing evidence and examples for the main idea.

Importance of topic sentences

In essays or articles , where subjects can shift from one paragraph to another, a topic phrase is particularly crucial. The topic sentences, superficially, may seem to serve the purpose of only acting like the initial or introductory sentence of a paragraph. But it has numerous other purposes that make it an important part of essays.

• Topic sentences link paragraphs together to improve the sentence flow and make reading easier. When topic sentences are not used, switching between paragraphs can feel abrupt and jarring to the reader. Authors can maintain the rhythm of their writing using topic sentences and facilitate smooth transitions.
• Topic sentences show the reader a sample of what to expect from the paragraph. The readers can determine from the topic sentence whether the paragraph will comprise a narrative, a list, anecdotal evidence, statistical data, persuasive opinions, or some other form of evidence.
• If two conflicting viewpoints are presented in a single paragraph, authors can use more than one topic sentence to inform the readers about the changes in the main concept. For example, paragraphs that “compare and contrast” require more than one topic sentence. In these kinds of paragraphs, authors can start with a topic sentence introducing the first idea and follow it up with proof or evidence supporting the idea. Then they can introduce the second topic sentence conveying the opposing viewpoint, followed by proof or evidence supporting it.

Different types of topic sentences

The different types of topic sentences include:

Simple statement

This topic sentence is used by authors to make a general observation or statement and then elaborate on it in the body of the paragraph.

New studies are emerging indicating the link between climate change and the emergence of numerous new virus strains.

Interrogative or question

This is used by writers in less formal settings. Authors can start a paragraph using implicit or explicit questions related to the topic of discussion to engage the readers.

How many nations are ready to adapt to rising sea levels?

Complex topic sentences are used when the author is discussing a complicated concept that encompasses multiple ideas. Such topic sentences cover more than a single core idea.

Although many people believe that a mother bird will reject its chick if it is touched by humans, the truth is that birds do not abandon their babies after humans touch them.

Authors can use their topic sentences to make explicit demands or pleas to their readers. This will be helpful in breaking the monotony of the essay.

Let’s look at the data from the latest research.

Purely transitional

Though topic sentences are generally responsible for facilitating a smooth transition between paragraphs, occasionally they are purely transitional. These function best when the main topic shifts abruptly by highlighting the switch.

But not everybody agrees.

Pivot sentences are not found at the beginning of a paragraph but rather in the middle, indicating a change in the topic. Conjunctive adverbs like however, furthermore, and meanwhile are frequently used with them.

However, the undisputed king of tennis, Roger Federer, was dethroned in 2008 at Wimbledon.

How to create good topic sentences

A good topic sentence can be created using some simple steps:

1. Determine the key point of your essay

Writers should first form an understanding of the topic of the essay and then create topic sentences to attract the attention of readers. Constructing a good thesis statement can assist the writer in forming better topic sentences.

2. Have an outline for the essay

The author should form a plan or roadmap beforehand on the topics they want to discuss in a paragraph and the evidence they want to use as supporting statements.

3. Be coherent and clear

Writers should make their topic sentences clear and comprehensible so that the reader can form a clear understanding of what to expect in the paragraph.

4. Share opinions

It is advisable to share the opinion or viewpoint of the author in the topic sentence to attract the attention of the reader. Authors should also refrain from writing obvious facts in the topic sentences.

5. Use specific wordings

The topic sentences ought to be precise enough so that the authors can use a few sentences in the paragraph to support them.

6. Transitions should be added between paragraphs

To give the essay or paper a throughline, authors can create topic sentences that refer to the prior paragraph. A topic sentence can make a reference to the preceding paragraph while introducing the next part by using transitional words.

7. Use new, relevant information

Instead of using an obvious fact that everybody knows as the topic sentence, authors can give new information. It is also important to present them in an interesting way.

8. Create a compound or complex topic statement

Compound or complex topic statements feel advanced and stronger. Authors can create such topic statements to add a high level of sophistication to their text.

Many beginner writers and students confuse thesis statements with topic sentences. In essence, thesis statements establish the major idea discussed in the entire essay or paper, as opposed to topic sentences, which introduce the central concept of a paragraph.

Both of these sentences are responsible for giving the readers a sample of what to expect, but in entirely different capacities. Suppose a person is writing a thesis about the different compounds present in coffee and the health benefits it offers.

The thesis statement will be a generalized statement indicating that there are numerous compounds in coffee that benefit the health of humans. But the topic sentence of each paragraph will introduce any single health benefit or compound present in the coffee.

Topic sentences are typically found at the beginning of a paragraph. But this does not mean that they cannot be placed elsewhere in the paragraph. In some cases, when the details discussed can be summarized into a general statement, topic sentences can be included at the end.

Similarly, in some paragraphs where multiple concepts are discussed, topic sentences may be used in the middle of the paragraph. The placement depends on the number of topics being discussed and the way they are discussed.

A topic sentence is a  sentence , sometimes at the beginning of a paragraph , that states or suggests the main idea (or topic ) of a paragraph.

Not all paragraphs begin with topic sentences. In some, the topic sentence appears in the middle or at the end. In others, the topic sentence is implied or absent altogether.

Examples and Observations

• " Salva and the other boys made cows out of clay. The more cows you made, the richer you were. But they had to be fine, healthy animals. It took time to make a lump of clay look like a good cow. The boys would challenge each other to see who could make the most and best cows." (Linda Sue Park, A Long Walk to Water . Clarion, 2010)
• " Momma bought two bolts of cloth each year for winter and summer clothes. She made my school dresses, underslips, bloomers, handkerchiefs, Bailey's shirts, shorts, her aprons, house dresses and waists from the rolls shipped to Stamps by Sears and Roebuck. . . ." (Maya Angelou, I Know Why the Caged Bird Sings . Random House, 1969)
• " You discover what it is like to be hungry. With bread and margarine in your belly, you go out and look into the shop windows. Everywhere there is food insulting you in huge, wasteful piles; whole dead pigs, baskets of hot loaves, great yellow blocks of butter, strings of sausages, mountains of potatoes, vast Gruyère cheeses like grindstones. A snivelling self-pity comes over you at the sight of so much food. You plan to grab a loaf and run, swallowing it before they catch you; and you refrain, from pure funk." (George Orwell, Down and Out in Paris and London . Victor Gollancz, 1933)
• " The flavor that salt imparts to food is just one of the attributes that manufacturers rely on. For them, salt is nothing less than a miracle worker in processed foods. It makes sugar taste sweeter. It adds crunch to crackers and frozen waffles. It delays spoilage so that the products can sit longer on the shelf. And, just as importantly, it masks the otherwise bitter or dull taste that hounds so many processed foods before salt is added." (Michael Moss, Salt, Sugar, Fat: How the Food Giants Hooked Us . Random House, 2013)
• " The very idea of retirement is a relatively new invention. For most of human history, people worked until they died or were too infirm to lift a finger (at which point they died pretty fast anyway). It was the German statesman Otto von Bismarck who first floated the concept, in 1883, when he proposed that his unemployed countrymen over the age of 65 be given a pension. This move was designed to fend off Marxist agitation—and to do so on the cheap, since few Germans survived to that ripe old age." (Jessica Bruder, "The End of Retirement." Harper's , August 2014)
• " Grandma's room I regarded as a dark den of primitive rites and practices. On Friday evenings whoever was home gathered at her door while she lit her Sabbath candles. . . ."  (E.L. Doctorow, World's Fair . Random House, 1985)
• " Genealogy is an ancient human preoccupation. The God of Hebrew Scripture promised Abraham descendants beyond number, like the stars in the sky and the sand on the seashore. The apostles Matthew and Luke claim that Abraham's lineage went on to include King David and eventually Jesus, though the specifics of their accounts are contradictory. Muslims trace Mohammed's line back through Abraham, to Adam and Eve." (Maud Newton, "America's Ancestry Craze." Harper's , June 2014)
• " O nce, in a restaurant in Italy with my family, I occasioned enormous merriment, as a nineteenth-century humorist would have put it, by confusing two Italian words. I thought I had, very suavely, ordered for dessert fragoline —those lovely little wild strawberries. Instead, I seem to have asked for fagiolini —green beans. The waiter ceremoniously brought me a plate of green beans with my coffee, along with the flan and the gelato for the kids. The significant insight the mistake provided—arriving mere microseconds after the laughter of those kids, who for some reason still bring up the occasion, often—was about the arbitrary nature of language: the single 'r' rolled right makes one a master of the trattoria, an 'r' unrolled the family fool. . . ." (Adam Gopnik, "Word Magic." The New Yorker , May 26, 2014)
• " In seventeenth-century Europe, the transformation of man into soldier took on a new form, more concerted and disciplined, and far less pleasant, than wine. New recruits and even seasoned veterans were endlessly drilled, hour after hour, until each man began to feel himself part of a single, giant fighting machine. . . ." (Barbara Ehrenreich, Blood Rites: Origins and History of the Passions of War . Henry Holt and Company, 1997)
• " What is the appeal of train travel? Ask almost any foamer, and he or she will invariably answer, 'The romance of it!' But just what this means, they cannot really say. It's tempting to think that we are simply equating romance with pleasure, with the superior comfort of a train, especially seated up high in the observation cars. . . ." (Kevin Baker, "21st Century Limited: The Lost Glory of America's Railroads." Harper's , July 2014)
• " Because science fiction spans the spectrum from the plausible to the fanciful, its relationship with science has been both nurturing and contentious. For every author who meticulously examines the latest developments in physics or computing, there are other authors who invent 'impossible' technology to serve as a plot device (like Le Guin’s faster-than-light communicator, the ansible) or to enable social commentary, the way H. G. Wells uses his time machine to take the reader to the far future to witness the calamitous destiny of the human race." (Eileen Gunn, "Brave New Words." Smithsonian , May 2014)
• " I passed all the other courses that I took at my university, but I could never pass botany. . . ." (James Thurber, My Life and Hard Times . Harper & Row, 1933)
• " What is there about this wonderful woman? From next door, she comes striding, down the lawn, beneath the clothesline, laden with cookies she has just baked, or with baby togs she no longer needs, and one's heart goes out. Pops out. The clothesline, the rusted swing set, the limbs of the dying elm, the lilacs past bloom are lit up like rods of neon by her casual washday energy and cheer, a cheer one has done nothing to infuse." (John Updike, "One's Neighbor's Wife." Hugging the Shore: Essays and Criticism . Knopf, 1983)
• " Television. Why do I watch it? The parade of politicians every evening: I have only to see the heavy, blank faces so familiar since childhood to feel gloom and nausea. . . ." (J.M. Coetzee, Age of Iron . Random House, 1990)
• " Anyone who has made the coast-to-coast journey across America, whether by train or by car, has probably passed through Garden City, but it is reasonable to assume that few travelers remember the event. It seems just another fair-sized town in the middle--almost the exact middle--of the continental United States. . . ." (Truman Capote, In Cold Blood . Random House, 1966)
• " Rodeo, like baseball, is an American sport and has been around almost as long. . . ." (Gretel Ehrlich, The Solace of Open Spaces . Viking Penguin, 1985)
• " What a piece of work is a book! I am not talking about writing or printing. I am talking about the codex we may leaf through, that may be put away on a shelf for whole centuries and will remain there, unchanged and handy. . . ." (William Golding, A Moving Target . Farrar, Straus and Giroux, 1982)

Characteristics of an Effective Topic Sentence

• "A good topic sentence is concise and emphatic . It is no longer than the idea requires, and it stresses the important word or phrase. Here, for instance, is the topic sentence which opens a paragraph about the collapse of the stock market in 1929: "The Bull Market was dead."(Frederick Lewis Allen) Notice several things. (1) Allen's sentence is brief . Not all topics can be explained in six words, but whether they take six or sixty, they should be phrased in no more words than are absolutely necessary. (2) The sentence is clear and strong: you understand exactly what Allen means. (3) It places the keyword—'dead'—at the end, where it gets heavy stress and leads naturally into what will follow. . . . (4) The sentence stands first in the paragraph. This is where topic sentences generally belong: at or near the beginning." (Thomas S. Kane, The New Oxford Guide to Writing . Oxford Univ. Press, 1988)

Positioning a Topic Sentence

"If you want readers to see your point immediately, open with the topic sentence . This strategy can be particularly useful in letters of application or in argumentative writing. . . . "When specific details lead up to a generalization, putting the topic sentence at the end of the paragraph makes sense. . . . "Occasionally a paragraph's main idea is so obvious that it does not need to be stated explicitly in a topic sentence." (Andrea Lunsford, The St. Martin's Handbook . Bedford/St. Martin's, 2008)

Guidelines for Composing Topic Sentences

"The topic sentence is the most important sentence in your paragraph. Carefully worded and restricted, it helps you generate and control your information. An effective topic sentence also helps readers grasp your main idea quickly. As you draft your paragraphs, pay close attention to the following three guidelines:

• Make sure you provide a topic sentence. . . .
• Put your topic sentence first.
• Be sure your topic sentence is focused. If restricted, a topic sentence discusses only one central idea. A broad or unrestricted topic sentence leads to a shaky, incomplete paragraph for two reasons:
• The paragraph will not contain enough information to support the topic sentence .
• A broad topic sentence will not summarize or forecast specific information in the paragraph."

(Philip C. Kolin, Successful Writing at Work , 9th ed. Wadsworth, 2010)

Testing for Topic Sentences

"When testing your article for topic sentences , you should be able to look at each paragraph and say what the topic sentence is. Having said it, look at all the other sentences in the paragraph and test them to make sure they support it. . . .

"If you find that you have come up with the same topic sentence more than once, you have two paragraphs doing the same work. Cut one of them out.

"If you find a paragraph that has several sentences that don't support the topic sentence, see if all the outlaw sentences support some other topic sentence and turn the one paragraph into two." (Gary Provost, "How to Test Your Articles for the 8 Essentials of Nonfiction." Handbook of Magazine Article Writing , ed. by Jean M. Fredette. Writer's Digest Books, 1988)

Frequency of Topic Sentences

"Teachers and textbook writers should exercise caution in making statements about the frequency with which contemporary professional writers use simple or even explicit topic sentences in expository paragraphs. It is abundantly clear that students should not be told that professional writers usually begin their paragraphs with topic sentences."  (Richard Braddock, "The Frequency and Placement of Topic Sentences in Expository Prose." Research in the Teaching of English . Winter 1974)

Elements of a Good Topic Sentence

Common pitfalls to avoid.

• Where To Get Your Essay Edited For Free

Crafting the perfect essay takes time and dedication. There are so many elements you have to worry about, such as tone, purpose, and correct spelling and grammar. Writing a strong topic sentences is another critical part in writing a cohesive essay. 

Without a strong topic sentence, you risk losing your reader and perhaps part of your grade. If it’s a college admissions essay, then you need it to be as strong as possible to back up your application. Learn about what steps you should take to write a strong topic sentence.

What Is a Topic Sentence? 

People often confuse a topic sentence with a thesis statement. A thesis statement is typically at the end of your opening paragraph, that dictates the main argument you’ll be making in your essay. 

Throughout your essay, you’ll have multiple topic sentences, as each paragraph should start off with one. This beginning sentence is used to direct the topic of the paragraph and outline the flow of the following sentences. It’s used to help guide your reader and to continue to keep them hooked on your overall essay. Without topic sentences, your essay will be unorganized, lack transitions, and sound very choppy. To write a good topic sentence, there are several steps to take.

Writing a Good Topic Sentence: 5 Steps

Step 1: decide what you’re going to write about..

When you see the essay prompt, you’ll have some time to think through what you want to say and why. You have to decide if it’s a persuasive essay, informative, narrative, or descriptive. Determine your purpose for writing the essay after reading through the prompt. Whether it’s an assignment for school or if it’s to get into college, you need to make sure you have that purpose clearly outlined. 

Step 2: Create a thesis statement.

One of the first things you need to do is create a thesis statement. This is typically a sentence with three points that you’ll back up throughout your essay. 

For example: The Office became a cultural phenomenon because it spurred the careers of many of today’s successful movie stars, it talked about situations that most American workers can relate to, and even 15 years later, offers funny, relevant content that helps to break down prejudices. 

You then use that thesis statement to create an essay around the points you want to make. 

Step 3: Make your essay outline.

Once you have the points you want to make within your thesis statement hammered out, make an outline for your essay. This is where you’ll start to create your topic sentence for each paragraph. You want to clearly state the main idea of that paragraph in the very first sentence. From there, you back up that main idea with facts and reputable sources. Make sure your topic sentence is clear, but does not just announce your topic. 

For example, do not write something like: “In this paragraph, I will discuss why it’s bad that poachers are killing giraffes.”

Instead, write something that clearly states your idea with a reasonable opinion and that gives direction to the paragraph: “Giraffes are a key part of the African ecosystem, so it’s important to enforce regulations against the poachers who are killing them for their body parts.” 

You’d then follow that up with reasons why giraffes are a key part of the African ecosystem and how poachers are destroying their population.

Step 4: Begin writing your essay.

Once you have your thesis statement and you’ve created an outline with supporting paragraphs and their topic sentences, you can begin writing your essay. It’s important to make that outline before just jumping in–a disorganized essay can spell disaster for you as you continue to write, and could result in a poor grade. Many times, teachers will even require you to turn in your outline as part of your overall essay grade. 

Step 5: Proofread and check your resources.

After you’ve written the essay, go back through it with a fine tooth comb. Read through each topic sentence and the paragraphs that follow to ensure that you’ve written clear, solid topic sentences throughout and that the paragraphs with them make sense. During the proofreading phase, you also need to recheck the sources you’re using. Make sure each source is reputable. In other words, do not use sites like Wikipedia where anyone can go in and edit an article to add misinformation. Use sites that:

• Are actual reputable news sources, such as the New York Times , CNN, CBS News
• Have domain names that end in .edu or .gov
• Come from an encyclopedia, such as Encyclopedia Britannica

Using sites that are not reputable could jeopardize the validity of your argument.

Now that you know the steps to set yourself up for success when writing a topic sentence, there are certain elements that go into a quality first sentence. Always make sure that your topic sentence is the first sentence of a paragraph. You don’t want to make your reader hunt for the point you’re trying to make. Check out some key elements of a good topic sentence:

Make sure your topic sentence isn’t too vague.

You need a topic sentence that has some specifics to it. It also needs to hook in your reader in some way with an opinion. A vague sentence makes it harder to write a paragraph that can clearly backs up your thoughts. For example:

DON’T: “In Pride and Prejudice, Mr. Bingley seems like a nice guy.”

DO: “When Mr. Bingley is first introduced, he comes across as a kind person because he speaks to everyone and doesn’t immediately pass judgment.”

Choose a reasonable opinion.

Your topic sentence should clearly outline whatever point you’re trying to make in the paragraph, but you want to pick a reasonable opinion that you can easily reinforce with facts and statistics. Here’s an example of what you should and should not do:

DON’T: “It’s obvious that Mr. Bingley was a total loser with no backbone.”

DO: “Mr. Bingley could have shown more confidence in his choices and stood up to Mr. Darcy when he found himself in love with Jane Bennet.”

You can then back that up with facts, saying that he was a wealthy Englishman and thus one of the key players in society at the time, which should have given him more confidence. If he’d been more confident, perhaps he would not have left and devastated Jane.

Use your topic sentence as a transition.

Along with telling the reader the point of your next paragraph, your topic sentence should also serve as a transition from the previous paragraph. Without a transition, the essay can feel like it’s choppy and disjointed. For example:

DON’T: “Mr. Bingley is a good man and here’s why.”

DO: “Although Mr. Bingley did break Jane’s heart by leaving, he ended up redeeming himself by returning to Netherfield Hall.”

Keep your topic sentence short.

A long, drawn-out topic sentence can risk losing your reader. Many times, it’s hard to determine the point of a sentence when it goes on for too long. You want a clear, concise sentence that draws in the reader but also leaves some room for you to expand on it in the following paragraph.

DON’T: “Throughout the novel of Pride and Prejudice, Mr. Bingley was often quite different from Mr. Darcy as he would treat all people in a friendly manner, considering them all his friends and acquaintances, even agreeing to throw a ball after Elizabeth’s sisters rudely demanded he do so and was gracious to Mr. and Mrs. Bennet as well despite their manners.”

DO: “Overall, Mr. Bingley served as a foil to Mr. Darcy throughout the story by treating everyone around him equally with dignity and grace.”

Writing an essay can be overwhelming at times, but so long as you avoid some of these common pitfalls, it can be easier to get it done on time. 

Don’t wait until the last minute.

If your teacher assigns you an essay or tells you that you have an essay test coming up, don’t wait until the day before to do anything about it. You have to plan or study and you need to give yourself time to do that. If you know it takes you a while to write something, then start planning it as soon as you get the assignment.

Don’t forget to write an outline.

Along with planning, make sure you have that outline written up and planned out well. It will serve as your guideline for writing the essay. Without it, you’ll face the risk of a disorganized essay that does not clearly illustrate your point.

Ask for help if you need it.

This may be the most important pitfall to avoid. If you get in over your head while writing, don’t be afraid to ask for help. Ask a friend to review the essay or ask your teacher for guidance.

Paragraphs: Topic Sentences

• Academic Paragraphs: Introduction to Paragraphs and the MEAL Plan (video transcript)
• Academic Paragraphs: Examples of the MEAL Plan (video transcript)

The best way to understand the role of the topic sentence in paragraph development is to imagine that any given paragraph is a miniature essay that has its own thesis, support, and conclusion. The parts of a paragraph easily correspond to the parts of an essay:

Just as an effective essay starts off with an introduction that presents the paper's thesis statement and indicates the specific claim or argument that the essay will develop, each paragraph should begin with a topic sentence that indicates the focus of that paragraph, alerting the reader to the particular subtopic that the paragraph will provide evidence to support.

A strong topic sentence should be placed at or near the beginning of a paragraph. In addition, this sentence should focus on a specific issue, avoid the use of direct quotations, and leave room for support and analysis within the body of the paragraph. Read on to learn more about creating an effective topic sentence.

The topic sentence does not have to be the first sentence in the paragraph; however, it should come early in the paragraph in order to orient the reader to the paragraph's focus right away. Occasionally a writer may place a transition sentence before the topic sentence, to create continuity between topics.

Topic Sentence to begin paragraph:

In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

Transition Sentence + Topic Sentence to begin paragraph:

However, Morrison does not only use the emotional and spiritual bonds between her female characters to initiate their coming-of-age. In addition, the author uses the physical bonds of female friendship to propel her adolescent protagonists into self-awareness.

Specificity

Your topic sentence should be more narrowly focused than your thesis sentence, and you will want to make sure the claim you are making can be supported, argued, and analyzed within the body of your paragraph.

Example: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

In this topic sentence, the essayist is arguing that physical bonds of friendship, specifically, make the female characters more self-aware. Because this idea can be refuted or supported by readers (based on how successfully the essayist persuades his or her readers with examples and analysis from the novel), and because the claim is narrow enough to address within a single paragraph, the above sentence is a successful topic sentence.

Direct Quotations (Are Best Avoided)

Although it might be tempting to begin a paragraph with a compelling quotation, as a general rule, topic sentences should state the main idea of the paragraph in your own words. Direct quotations have a place later in the paragraph, where they may be incorporated to support the topic sentence.

Needs Improvement: As Morrison (1982) conveyed, the girls' "friendship let them use each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

Better: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness. Pointing to the connection of eyes meeting and bodies growing together, Morrison makes coming-of-age an interactive physical process between the adolescent protagonists. Specifically, Morrison describes how Sula and Nel have used "each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

In this second paragraph, the topic sentence appears first, immediately orienting readers to the main focus (or topic) of the paragraph. The quotation is used later in the paragraph as a form of evidence or support for the topic sentence.

If you are finding it challenging to create effective topic sentences, you might consider outlining before beginning to write a paper. The points and subpoints of an outline can then become the topic sentences for the paper's paragraphs.

Additionally, because the topic sentence functions similarly at the paragraph level to the thesis at the essay level, you may also find it helpful to check out our thesis statement construction information. Our resource on paragraphs has helpful information about the scope of a paragraph, as well.

Writing Topic Sentences — Purpose, Structure, and Examples

What is a topic sentence.

A topic sentence in academic writing identifies how a body paragraph relates to the overall purpose of an essay stated in the thesis statement . Topic sentences are usually at the beginning of a paragraph and identify the paragraph’s controlling idea.

While an essay’s thesis statement identifies the point of the essay in its entirety, the topic sentence has a much narrower focus, as it relates only to the paragraph in which it is located.

What is the purpose of a topic sentence?

The purpose of a topic sentence is to inform the reader of the main idea of the paragraph and how it connects to the overall objective of the essay. An effective topic sentence accomplishes one or more of the following:

Makes a claim

Supports other claims made in the paper

Identifies the purpose of the rest of the paragraph

Relates the paragraph to the purpose of the paper

Precedes information that defends a claim

How to write a topic sentence

To write a topic sentence, incorporate the following guidelines:

Determine the thesis of the essay.

Identify the main supports that help prove the thesis.

Use each main support to structure a topic sentence for each paragraph.

Compose a sentence that answers the following questions:

What will the paragraph prove?

How does the paragraph connect to the thesis?

Where is the topic sentence in a paragraph?

Topic sentences can be placed at the beginning or end of a paragraph.

Although it does not need to be the first sentence, the topic sentence should be placed at the beginning of the paragraph so the reader can quickly identify the purpose of the paragraph.

While not a common placement for a topic sentence, some writers use topic sentences at the end of a paragraph. Writers who choose this method want the reader to deduce the main point of the paragraph by presenting the evidence first.

Topic sentence examples

The following list identifies topic sentences based on the provided thesis statements for five-paragraph essays:

Thesis Statement: Capital punishment should be banned because it is inhumane, unconstitutional, and ineffective at deterring crime.

Support Paragraph 1 Topic Sentence: The inhumane nature of the death penalty proves it should be abolished.

Support Paragraph 2 Topic Sentence: Capital punishment should be outlawed because it violates the Constitution.

Support Paragraph 3 Topic Sentence: Because the death penalty does not effectively deter criminal behavior, states should not continue to use it.

Thesis Statement: College athletes should be financially compensated because they sacrifice their minds and bodies, cannot hold an outside job, and increase the school’s revenue.

Support Paragraph 1 Topic Sentence: Student athletes should be paid for their performance because of sports’ impact on their minds and bodies.

Support Paragraph 2 Topic Sentence: Because most college athletes cannot play their sport and hold a job, colleges should give them a living wage.

Support Paragraph 3 Topic Sentence: Student-athletes’ ability to increase their college’s revenue proves they should be awarded financial compensation.

Thesis Statement: Using alternative energy sources can help lessen the impact of global climate change.

Support Paragraph 1 Topic Sentence: Through the widespread use of solar power, countries can limit the environmental impact of other energy sources.

Support Paragraph 2 Topic Sentence: Utilizing more wind turbines as a power source can help mitigate the effects of climate change.

Support Paragraph 3 Topic Sentence: Using geothermal power will effectively decrease the world's reliance on fossil fuels.

What is a topic sentence?

A topic sentence states the main point of a paragraph: it serves as a mini-thesis for the paragraph. You might think of it as a signpost for your readers—or a headline—something that alerts them to the most important, interpretive points in your essay. When read in sequence, your essay’s topic sentences will provide a sketch of the essay’s argument. Thus topics sentences help protect your readers from confusion by guiding them through the argument. But topic sentences can also help you to improve your essay by making it easier for you to recognize gaps or weaknesses in your argument.

Where do topic sentences go?

Topic sentences usually appear at the very beginning of paragraphs. In the following example from Anatomy of Criticism , Northrop Frye establishes the figure of the tragic hero as someone more than human, but less than divine. He backs up his claim with examples of characters from literature, religion and mythology whose tragic stature is a function of their ability to mediate between their fellow human beings and a power that transcends the merely human:

The tragic hero is typically on top of the wheel of fortune, half-way between human society on the ground and the something greater in the sky. Prometheus, Adam, and Christ hang between heaven and earth, between a world of paradisal freedom and a world of bondage. Tragic heroes are so much the highest points in their human landscape that they seem the inevitable conductors of the power about them, great trees more likely to be struck by lightning than a clump of grass. Conductors may of course be instruments as well as victims of the divine lightning: Milton’s Samson destroys the Philistine temple with himself, and Hamlet nearly exterminates the Danish court in his own fall.

The structure of Frye’s paragraph is simple yet powerful: the topic sentence makes an abstract point, and the rest of the paragraph elaborates on that point using concrete examples as evidence.

Does a topic sentence have to be at the beginning of a paragraph?

No, though this is usually the most logical place for it. Sometimes a transitional sentence or two will come before a topic sentence:

We found in comedy that the term bomolochos or buffoon need not be restricted to farce, but could be extended to cover comic characters who are primarily entertainers, with the function of increasing or focusing the comic mood. The corresponding contrasting type is the suppliant, the character, often female, who presents a picture of unmitigated helplessness and destitution. Such a figure is pathetic, and pathos, though it seems a gentler and more relaxed mood than tragedy, is even more terrifying. Its basis is the exclusion of an individual from the group; hence it attacks the deepest fear in ourselves that we possess—a fear much deeper than the relatively cosy and sociable bogey of hell. In the suppliant pity and terror are brought to the highest possible pitch of intensity, and the awful consequences of rejecting the suppliant for all concerned is a central theme of Greek tragedy.

The context for this passage is an extended discussion of the characteristics of tragedy. In this paragraph, Frye begins by drawing a parallel between the figure of the buffoon in comedy and that of the suppliant in tragedy. His discussion of the buffoon occurred in a earlier section of the chapter, a section devoted to comedy. The first sentence of the current paragraph is transitional: it prepares the way for the topic sentence. The delayed topic sentence contributes to the coherence of Frye’s discussion by drawing an explicit connection between key ideas in the book. In essays, the connection is usually between the last paragraph and the current one.

Sometimes writers save a topic sentence for the end of a paragraph. You may, for example, occasionally find that giving away your point at the beginning of a paragraph does not allow you to build your argument toward an effective climax.

How do I come up with a topic sentence? And what makes a good one?

Ask yourself what’s going on in your paragraph. Why have you chosen to include the information you have? Why is the paragraph important in the context of your argument? What point are you trying to make?

Relating your topic sentences to your thesis can help strengthen the coherence of your essay. If you include a thesis statement in your introduction, then think of incorporating a keyword from that statement into the topic sentence. But you need not be overly explicit when you echo the thesis statement. Better to be subtle rather than heavy-handed. Do not forget that your topic sentence should do more than just establish a connection between your paragraph and your thesis. Use a topic sentence to show how your paragraph contributes to the development of your argument by moving it that one extra step forward. If your topic sentence merely restates your thesis, then either your paragraph is redundant or your topic sentence needs to be reformulated. If several of your topic sentences restate your thesis, even if they do so in different words, then your essay is probably repetitive.

Does every paragraph need one?

No, but most do. Sometimes a paragraph helps to develop the same point as in the previous paragraph, and so a new topic sentence would be redundant. And sometimes the evidence in your paragraph makes your point so effectively that your topic sentence can remain implicit. But if you are in doubt, it’s best to use one.

Topic Sentence

Every paragraph should include a topic sentence that identifies the main idea of the paragraph. A topic sentence also states the point the writer wishes to make about that subject. Generally, the topic sentence appears at the beginning of the paragraph. It is often the paragraph’s very first sentence. A paragraph’s topic sentence must be general enough to express the paragraph’s overall subject. However, it should be specific enough that the reader can understand the paragraph’s main subject and point.

• The topic sentence should identify the main idea and point of the paragraph. To choose an appropriate topic sentence, read the paragraph and think about its main idea and point.
• The supporting details in the paragraph (the sentences other than the topic sentence) will develop or explain the topic sentence. Read all the supporting details in the paragraph and think about the ideas they discuss.
• The topic sentence should not be too general or too specific. When considering the options, look for a topic sentence that is general enough to show the paragraph’s main idea instead of just one of its details. The answer should be specific enough that the reader understands the main idea of the paragraph.

More About the Topic Sentence

A topic sentence is the most important sentence in a paragraph. Sometimes referred to as a focus sentence, the topic sentence helps organize the paragraph by summarizing the information in the paragraph. In academic writing, the topic sentence is usually the first sentence in a paragraph (although it does not have to be).

Purpose of the Topic Sentence

A topic sentence essentially tells readers about the rest of the paragraph. All sentences after it have to give more information about that sentence, prove it by offering facts about it, or describe it in more detail. For example, if the topic sentence concerns the types of endangered species that live in the ocean, then every sentence after that needs to expands on that subject.

Topic sentences also need to relate back to the thesis of the essay. The thesis statement is like a road map that will tell the reader or listener where you are going with this information or how you are treating it.

Topic Sentences and Controlling Ideas

Every topic sentence will have a topic and a controlling idea. The controlling idea shows the direction the paragraph will take.

Examples of a Topic Sentence

Topic Sentence: There are many reasons why pollution in ABC Town is the worst in the world.

The topic is "pollution in ABC Town is the worst in the world" and the controlling idea is "many reasons."

Topic Sentence: To be an effective CEO requires certain characteristics.

The topic is "To be an effective CEO" and the controlling idea is "certain characteristics."

Topic Sentence: There are many possible contributing factors to global warming.

The topic is "global warming" and the controlling idea is "contributing factors."

Topic Sentence: Fortune hunters encounter many difficulties when exploring a shipwreck.

The topic is "exploring a shipwreck" and the controlling idea is "many difficulties."

Topic Sentence: Dogs make wonderful pets because they help you to live longer.

The topic is "dogs make wonderful pets" and the controlling idea is "because they help you

to live longer."

Topic Sentence: Crime in poverty-stricken areas occurs because of a systemic discrimination.

The topic is "crime in poverty stricken areas" and the controlling idea is "systemic discrimination."

Topic Sentence: Teen pregnancy may be prevented by improved education.

The topic is "teen pregnancy may be prevented" and the controlling idea is "improved education."

Topic Sentence: Cooking requires a number of different skills.

The topic is "cooking" and the controlling idea is "many different skills."

Topic Sentence: It is important to be ready before buying a house.

The topic is "buying a house" and the controlling idea is “it is important to be ready."

Topic Sentence: Graduating from high school is important for many different reasons.

The topic is "graduating from high school" and the controlling idea is "many different reasons."

Topic Sentence: Having a first child is difficult because of the significant adjustments in your life.

The topic is "having a first child" and the controlling idea is "significant adjustments in your life."

Topic Sentence: Remodeling a kitchen successfully requires research and a good eye.

The topic is "remodeling a kitchen" and the controlling idea is "requires research and a good eye."

Topic Sentence Exercise

Write a topic sentence for the following paragraph. During the 1990s, I really enjoyed watching Friends on television every Thursday night. I really wanted Rachel’s haircut—I think every girl wanted Rachel’s haircut back then! Rachel’s haircut went really well with the Guess Jeans that were so popular in the 1990s. I remember all the advertisements for Guess and Calvin Klein Jeans that were in each month’s Sassy magazine. I do not think Sassy magazine exists anymore, but it was one of the most popular magazines for young women in the 1990s.

Topic Sentences

What is a topic sentence.

• A statement at the beginning of each body paragraph
• Indicates the topic of the entire paragraph
• In a short essay, it reflects one of the main points of the thesis statement (link to thesis statement handout)

Main Point + Details

An effective topic sentence expands on a main thesis point by including details and explanation. It has two organizational purposes:

• Relate back to the thesis statement
• Summarize the paragraph

An effective topic sentence is like a mini-thesis statement for each paragraph.

Example Thesis: Health-conscious individuals should consider substituting strawberries for desserts because strawberries are healthy , sweet , and versatile .   Topic of Body Paragraph 1: Strawberries are healthy   Topic of Body Paragraph 2: Strawberries are sweet   Topic of Body Paragraph 3: Strawberries are versatile

Topic Sentence for Body Paragraph 1: Strawberries are a healthy substitute for desserts because they have a much lower carbohydrate count and are rich in nutrients and fiber.  

Notice that the topic sentence includes the first main point of the thesis statement, but it expands on the idea with further details. Now the paragraph can elaborate further on these details, and it should relate back to the main argument – that strawberries can be substituted for desserts.

The second body paragraph would start with a topic sentence about the second main point: strawberries are sweet . The third body paragraph would start with a topic sentence about the third main point: strawberries are versatile .

Longer Essays

Not all papers will have a three point thesis statement. If this is the case, the topic sentence may not contain a word-for-word point stated in the thesis statement.

Example Thesis statement: The literary techniques used by Leo Tolstoy in The Death of Ivan Ilych unveil an extraordinary sense of depth within the novella that is imperative to truly understanding Tolstoy’s ideas.

Example Topic Sentence: When Leo Tolstoy employs the technique of symbolism, inanimate objects like Ivan’s golden pocket watch and the drapes on his windows convey hidden meanings that further clarify important themes in the story.

30 Topic Sentence Examples

June 24, 2024

What is an essay without a topic sentence? Well, confusion. In your writing, the topic sentence introduces what the paragraph will be about. It should cover the topic of the paragraph and the prime focus of what you want to discuss in the next several lines. And it can assist in smoothly transitioning into the next paragraph, the next point you’re about to make. Depending on the complexity of your argument, the topic sentence can also weave together several paragraphs. So when the topic sentence is missing, it’s easy to lose track of what your specific message is. Below, you find 30 topic sentence examples.

Think of the topic sentence as a tool in your writing kit. It’s there to help you signpost and structure the argument of your essay. Having it, while making sure the topic is interesting and clear, is essential to help your reader truly understand your thesis.

How do you write a topic sentence?

When you’re about to write an essay, you won’t find yourself immediately thinking of every topic sentence example at once. Figuring out what your thesis is going to be, the very purpose and argument of your essay, will be a necessary first step . Then you might want to create an outline . The outline can draft out what you want to cover in each paragraph or how your argument will be supported.

This is where the topic sentence comes in. For every paragraph, you can begin to think of topic sentence examples that best sum up the rest of your idea. The more interesting you can make the topic sentence, the better it will be, so long as you can support it. Remember, the topic sentence will introduce what you are going to discuss and expand on in the rest of the paragraph.

Examples (Continued)

Let’s take a look at these six topic sentence examples below that introduce a paragraph:

1) Studies over the last ten years have shown that the use of social media has a significant role in teenage mental health.

2) Kate Jackson and her family, who have all been San Francisco residents for 30 years, noted that this was the hottest summer yet.

3) Book sales across the country have actually increased this year, contrary to popular belief.

4) During COVID-19, people rushed to adopt pets, but after the pandemic ended many of those pets were surrendered to shelters.

5) It is undeniable what impact the meat industry has had on our environment.

6) In the 19th century in France, the creation of the Braille system was a significant turning point for those with disabilities.

How do you imagine the rest of the paragraph will turn out? How can you best support your topic sentence to strengthen your overall essay?

Support your paragraph with evidence

The topic sentence of your paragraph will not hold well if it is not backed up with the right evidence. After writing a topic sentence like the topic sentence examples above, the rest of your paragraph should include strong examples of evidence to support your argument. Doing so will only help validate your topic sentence and allow your reader to have more insight into your thesis.

Considering each topic sentence examples above, try to think of what types of evidence you would expect in that same paragraph. There could be reports on statistics, interviews, and other forms of evidence provided. How will yours be?

Where should the topic sentence go?

Now you know that your topic sentence should be followed by the right evidence. So it’s safe to assume that the topic sentence belongs at the very beginning of the paragraph.

Yet depending on the paragraph you’re working on, you can also place your “main” topic sentence after an “intro” topic sentence. Let’s take a look at the two examples below:

7) Due to rising temperatures around the world, people have had to flee their homes and relocate to areas less prone to fires or floods. (Intro topic sentence)

8) However, many have found that even these “safer” locations are still susceptible to eventual natural disasters. (Main topic sentence)

When we combine the two sentences, we get:

Due to rising temperatures around the world, people have had to flee their homes and relocate to areas less prone to fires or floods. However, many have found that even these “safer” locations are still susceptible to eventual natural disasters.

The first (intro) topic sentence example is more generic and introductory, functioning like a summary of an observation. The second (main) topic sentence example then presents another contradictory argument to that first point. Depending on the tone or argument you want to make in your paragraph, you can format your topic sentences in such a way to further sharpen your thesis. Whenever you have doubt though, you can always place one topic sentence at the beginning of the paragraph.

Sometimes less is more in writing the topic sentence

The topic sentence introduces the key concept of that paragraph, along with evidence and research findings. It can even be written as more than one sentence or perspective, as noted directly above. However, you also don’t want to say too much. Why?

You don’t want to give all of your information away at once. While it is imperative to write a clear, specific, and even complex topic sentence, it’s just as important to avoid being too general or too informative. Striking the right balance is going to help you structure the rest of your essay. After all, you have the rest of the paragraph and the rest of your essay to do that, which leads us to our next point.

Topic sentences for smoother transitions

Like a game of dominoes, your paragraphs are all connected and should flow smoothly into the next statement you are making. As you are building your outline, or even as you’re already writing, consider how your previous paragraph transitions into the next . This depends on the intention of each paragraph and how you are structuring your argument.

Topic sentences for paragraph transitions have many functions. They will elaborate on more examples. They can wrap up or summarize a preceding point you made, providing another perspective. Also, they can go against a fact or opinion you wrote, which is a great way to strengthen your overall thesis and they can also be posed as a question.

Take a look at these transitional topic sentence examples below:

9) In fact, walking as a form of exercise has shown to reduce cortisol levels.

10) Furthermore, city council representatives have said that environmental sustainability has remained at the top of the agenda, but activists have largely disagreed.

11) While the strike in Hollywood has come to an end, many writers are still without employment and searching for new ways to restart their careers.

12) However, grocery prices across the country still seem to have risen.

13) Despite the state’s discontinued funding for the arts, is there another feasible way for these students to gather together and flourish as young artists at their school?

More than one paragraph: Topic sentences that expand into several key points

So far we’ve covered topic sentences that elaborate on just one paragraph. However, you might find that one topic sentence (or two) can best address several paragraphs. This usually occurs when you’re trying to introduce a bigger argument to serve your essay.

Let’s take one of the single paragraph topic sentences from earlier above and expand it by adding a connecting topic sentence to it:

14)Book sales across the country have actually increased this year, contrary to popular belief.

15) A report from the Association of American Publishers’ StatShot program states that in April sales over a year there has been an 18% increase.

These two topic sentence examples can even serve as their own introductory paragraph. This can then lead into more paragraphs related to the topic of specific book sales increasing across the country:

Book sales across the country have actually increased this year, contrary to popular belief. A report from the Association of American Publishers’ StatShot program states that in April sales over a year there has been an 18% increase.

Make the topic sentence interesting, not obvious

Check out 15 more topic sentence examples below. How do they introduce the topic, and what does it make you want to learn more about? You can imagine what kind of paragraph, or paragraphs, might follow afterwards:

16) When brewed correctly, coffee can hold strong, subtle hints of flavors such as chocolate or fruit, depending on the level of acidity.

17) Although today life in 1920s Paris is often romanticized for its glamor, jazz, and fashion, the city was still struggling to recover from the devastation of World War I.

18) Strict social rules dominated the Victorian Era, despite Britain’s expansion around the world in pursuit of wealth and power.

19) Dogs have a keen sense of time, so much so that they can predict when you’re late to take them out for a walk.

20) Before winter arrives, birds such as cranes and waterfowl follow preferred aerial pathways during their yearly migrations.

21) Conservation methods have helped local farms in their efforts to prioritize sustainability.

22) Did you know that humans would have a better chance of reaching Mars if they had a base set up on the moon?

23) The Pacific Ocean covers more than 30 percent of the earth’s surface, and it is home to so many life forms that have not yet been studied.

24) It is often debated whether or not student athletes should be paid for their performance, considering the cost for them to succeed.

25) Becoming a successful CEO doesn’t just happen overnight.

26) Although purchasing a home is considered a great form of investment, potential buyers should look at the real estate market first.

27) Watching my mother work three jobs to support our family has taught me the importance of resilience and strong work ethic.

28) Historical fiction not only has the power to teach us of actual past events. It also allows us to step into the lives of those we would have never met.

29) Parents and teachers at Sunnyroad School District are advocating for schools to provide free computers for their students – but the administrators aren’t so sure.

30) Across the country, the debate around whether teenagers should be allowed to use smart phones on campus has been circulating.

The topic sentence as a guide

One way to look at topic sentences is to imagine them as guiding compasses of your essay. Whatever point you are trying to make, the topic sentence has the power to guide your reader down a certain path. Choose wisely!

Topic Sentences for Body Paragraphs: Examples and Explanation

A key to becoming a better writer is learning how to cover one main idea in each paragraph and write clearly—topic sentences can help you do that by focusing your writing.

Let’s look at what a topic sentence is, how to write a good topic sentence, and topic sentence examples.

What is a topic sentence in a paragraph?

A topic sentence is a sentence that introduces the main idea of the paragraph—it tells the reader what the paragraph is about in a clear and concise manner. It organizes an essay, engages the reader, provides a focus for the paragraph, and relates each paragraph back to the thesis.

A topic sentence is generally the first sentence in your body paragraph or at least at the beginning of the paragraph.

Topic sentences provide structure and organization to your essay—this is helpful for both the writer and the reader.

You have to build on your topic sentence. You make your claim in the topic sentence, which serves as a base to add your supporting details, evidence, and examples that strengthen your argument.

The purpose of a topic sentence is to provide a clear focus for your paragraph and preview what you will discuss in the paragraph.

Is the topic sentence always the first sentence?

The topic sentence is usually at the beginning to help the reader understand what the paragraph is about. However, a topic sentence can be in the middle or end of the paragraph (though this would be rare for body paragraphs).

Can a topic sentence be more than one sentence?

A topic sentence is traditionally one sentence—this is recommended to state your point clearly and concisely. However, a topic sentence can be 2 or 3 sentences long if you are explaining the claim.

If you decide you must make your topic sentence longer to express your main idea, make sure to edit and try to remain as concise as possible. Also, do not overly use multiple topic sentences, as this can make your essay lack focus or structure.

Topic sentences for paragraphs that are not a part of an essay

What is a good topic sentence.

A good topic sentence is clear and concise. It is general enough to cover what the entire paragraph is about but specific enough to make it easy to understand the main idea of what will be discussed. It should relate back to the thesis or question and help maintain the flow of the essay.

How to write a topic sentence for a body paragraph

Effective strategies for writing a topic sentence include that you pivot between ideas, make sure that you express the topic and what you will talk about in the paragraph, and use transition words—such as although, another example/way/argument, even though, in addition to, likewise, therefore, or however.

Make sure you then expand on the statement and give supporting details and reasons, examples, or sources.

Topic sentences for body paragraphs examples

Let’s look at topic sentences that illustrate your point that you will expand on, provide transitions, compare and contrast topics, show cause and effect relationships, express counterclaims that you will proceed to address, or answer a question.

Example 1: Stating your claim

These could look like:

If I only talk about the benefits of learning a new language on your memory, I would make my topic sentence more specific—”Learning a new language can improve a person’s memory.”

Example 2: Transitions

If your writing an opinion essay about why dogs make the best pets, and your previous paragraph said that they are good companions because they are loyal, your next paragraph could start with the topic sentence: “Another reason why dogs are good companions is that they are affectionate.”

Example 3: Compare and contrast topics

For example: “While in-person classes offer better social interactions, online classes offer more flexibility.”

Example 4: Show cause and effect relationship

Example 5: introduce a counterclaim.

A topic sentence can also introduce a counterclaim.

Example 6: Answering a question

Let’s look at an example of a topic sentence that answers a question.

You can also answer a question in a topic sentence in an essay if you end the previous paragraph with a question.

Now that you know how to write a topic sentence and have seen topic sentences for body paragraphs examples, you are well on your way to becoming a better writer.

Topic Sentence and Paragraph Organization

Paragraph organization refers to the way sentences are structured and ordered to create a unified and cohesive body of text.

The principal features to consider in paragraph organization are the topic sentence and controlling idea, supporting details, organizational patterns, and signal words. Together, these features develop a topic and connect ideas from one point to the next, logically and fluidly. This resource explains these features and provides numerous examples of paragraph organization.

The Topic Sentence and Controlling Idea

Similar to a thesis statement, which establishes the central focus or point of a whole piece of writing, a topic sentence works at the paragraph level to express the focus and general point of an individual paragraph. A topic sentence has two parts: 1) the topic that is being discussed throughout the paragraph and 2) a controlling idea that limits the focus on the topic to one point or idea. Each additional sentence in the paragraph then develops or expounds on that point with supporting details. The example topic sentence below is from a body paragraph in an informative essay.

Example Topic Sentence and Controlling Idea

The economy also plays a role in an increase in prescription pain reliever addiction.

The example topic sentence suggests the paragraph topic is “the economy,” and the controlling idea about the economy is how it “plays a role in an increase” in opioid addition. The signal word “also” connects this topic as an additional example or contributing factor to the opioid epidemic, the focus of the paper. The example below shows the topic sentence in the context of the complete paragraph.

The economy also plays a role in an increase in prescription pain reliever addiction. According to Jungeun Olivia Lee, a social work professor at University of Southern California, “The relationship between joblessness and substance abuse is strongest among people from low socioeconomic brackets, who might not be able to afford healthier ways to relieve their stress” (2017, as cited in Khazan, 2017, para. 8). Additionally, every point the unemployment rate rises, opioid-related death rates rise by almost 4 percent (Khazan, 2017). Unemployment makes it not only difficult for those suffering from pain to afford medication or healthy alternatives, but it can also contribute to depression and varying degrees of self-medication and addiction.

Supporting Details

In a paragraph, the topic and controlling idea are developed with supporting details. Listed here are some types of supporting details found in paragraphs along with an example of each in a sentence.

Facts: statistics or evidence from research that can be verified

• The office sold seven million dollars of real estate during the boom years.

Opinions: statements, quotes, or paraphrases from subject matter experts

• According to expert tea maker, Millie Stoff, there are three easy steps to making tea.

Definitions: explanations of what a term or concept means

• A crossover is a family vehicle with the features of a sedan, a mini-van, and an SUV.

Examples: parts, pieces, instances, traits, or specimens that illustrate the essence or character of a greater whole.

• Mario is a shy, introverted young man. For example, he has few friends and mostly keeps to himself.

Anecdotes: narrative accounts of one time or recurring events

• When I visited the Washington Monument, I enjoyed the 180-degree view the most.

Descriptions: a visual or sensory depiction of a person, place, event, activity, or idea

• Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees.

Example Paragraph and Analysis of the Supporting Details

Hiking can be exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is6,684 feet above sea level. We first crossed a foot bridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

The topic sentence in the example paragraph indicates that the paragraph is on “hiking,” and the focus is that hiking is “exhilarating” during winter. The sentences in the paragraph support and develop this idea with an anecdote of the writer’s experience hiking up a mountain during winter. An anecdote is a narrative account that helps a reader understand an event or situation. Had the writer said hiking was “dangerous” instead of “exhilarating,” the anecdote in addition to the visual and sensory details, facts, and opinions about the experience would have been different. Additionally, while the sample paragraph is a personal account, writers in many professions use anecdotal evidence to report events from an objective point-of-view, where the writer is not a participant but rather a witness or observer.

Paragraph Organization

Along with having topic sentences and supporting details, paragraphs are also organized to achieve a certain purpose. However, just as a paragraph can contain different types of supporting details, a paragraph may also include more than one organizational pattern. Listed here are some common patterns for organizing a paragraph:

• Cause and Effect for showing how one thing leads to another
• Chronological Order for narrating events that occurred over time
• Classification for grouping things together according to their features
• Comparison and Contrast for showing how things are similar or different
• Definition and Example for defining a term or idea and then expanding it with examples
• Description for listing details
• Episode for presenting details or information about a specific event or anecdote
• General/Specific Order for presenting a general idea followed by specific examples
• Generalization/Principle for making a general statement or applying a broad principle to explain the supporting details
• Listing for presenting ideas from least to most important
• Order of Importance for building up to or leading away from the most important point.
• Problem and Solution for presenting an issue and a way to address it
• Process/Cause for explaining what or how something happens and then why
• Spatial Order for ordering details directionally

Signal Words

Signal words are signposts or clues to a paragraph’s organization. If the word “type” is used in a sentence, for example, it signals that the ideas involve types or classification, which is an organizational pattern. Signal words are context clues that hint at what the paragraph is about and how it is organized.

Listed here are signal words associated with different types of paragraph organization.

• Cause and Effect : because, consequently, for this reason, hence, and on account of
• Chronological Order : after, at last, at (time), as long as, at the same time, as soon as, before, during, eventually, finally, in (month or year), later, meanwhile, next, on (day or date), since, second, subsequently, then, until, and whenever
• Classification : categories, classes, classifications, elements, features, groups, kinds, methods, types, varieties, and ways
• Comparison and Contrast : another, both, however, likewise, one difference, on the other hand, on the contrary, similarity, similarly, unlike, and while

• General/Specific Order : for example, for instance, indeed, in fact, in other words, like, namely, such as, and that is
• Generalization/Principle : additionally, always, because of, clearly, conclusively, first, for instance, for example, furthermore, generally, however, if…then, in fact, it could be argued that, moreover, most convincing, never, not only…but also, often, second, therefore, third, truly, and typically
• Listing : additionally, also, and, as well as, besides, furthermore, in addition, in fact, moreover, or, plus, and too
• Order of Importance : central, chief, ending with, finishing with, key, lastly, least, main, major, finally, primary, principal, and significant
• Problem and Solution : answer, challenge, difficulty, dilemma, enigma, indicate, improve, issue, need, plan, problem, propose, resolve, respond, solve, and suggest
• Process/Cause : accordingly, as a result of, because, begins with, consequently, effects of, finally, first, for this reason, how to, how, if…then, in order to, is caused by, leads/led to, may be due to, next, so that, steps involved, therefore, thus, and when…then
• Spatial Order : above, below, behind, beside, down, east, feels, highest, looks, lowest, next to, north, smells, sounds, south, tastes, under, and west

Sample Paragraphs and Analyses of the Organization

The sample paragraphs in this section illustrate topic sentences, supporting details, organizational patterns, and signal words in context. Read each paragraph to identify the type of paragraph organization on your own, and then proceed to the analysis to check your comprehension.

Sample Paragraph 1

• In 1995, Lawrence started his real estate business, and it has since become a huge success. When Lawrence Real Estate opened its door in Oviedo, Florida, it sold seven million dollars of real estate during the first few boom years. By 2000, Lawrence decided to open two branch offices: one in Tampa in 2003 and one in Miami in 2004. By 2007, the home office and both the branch offices had survived the economic slowdown, so Lawrence and his associates expanded their business to the Carolinas and opened a branch office in Charlotte in 2020. It can be safely said that Lawrence Real Estate has become a model for success despite economic struggles and real estate devaluation.

Analysis of Paragraph 1: According to the topic sentence, which contains two coordinating clauses and therefore two subjects and two topics, this paragraph is about Lawrence and his real estate business, and the controlling idea is that they have been successful.

To understand how the supporting details are organized to present information about this topic and idea, the reader can consider the supporting details. To do this, they look at the way the sentences begin and at any signal phrases that lead readers along a certain line of thinking. Here are some key signal words: “in 1995,” “By 2000,” “By 2007,” and “in 2020.” These dates make a pattern. They go back to 1995 and then in a chronological order, they move forward to when the success of the business happened.

This paragraph uses chronological order . The reader will notice too that the last sentence returns to the beginning idea of 15 years ago. In this sentence, a final comment about the time period overall is given with respect to the new information

Sample Paragraph 2

• Making a great cup of tea is easy if you follow these three steps. First, heat a cup of water to the boiling point. Then put the tea bag in the hot water, and let it steep for at least three minutes. Finally, add creamer and sugar to taste. There is nothing tastier than a strong cup of tea early in the morning.

According to the topic sentence, which is the first sentence of the paragraph, making a cup of tea is the topic, and the controlling idea is that it’s easy to do if you follow three steps. Signal words open the following sentences: “first,” “then,” and “finally.” These indicate a sequence of steps, not times or dates as in a narrative story, but steps that happen in a specific order as in the process of doing something or informing others how to do something.

This paragraph uses process order (or process/cause). In the last sentence of this paragraph, the process is completed with a return to the original topic—a cup of tea—and a new comment about it—that a strong cup is tasty in the morning, making those three steps not only easy but also worthwhile.

Sample Paragraph 3

• The Washington Monument is divided into three main areas. The lowest section of the building houses the entrance, a gift shop, and a restaurant. The middle section consists of elevators and stairways to the top. The top section of the monument includes an observation deck with a spectacular view of the Washington D.C. area. When I visited the Washington Monument, I toured every section but enjoyed the spectacular 180-degree view the most.

Based on the topic sentence at the beginning of the paragraph, the topic is the Washington Monument, and the controlling idea is that it is divided into three main areas. The paragraph presents information about the lowest section first, the middle section second, and the top section third. The last sentence makes a remark about the most enjoyable of all the sections. This is an example of spatial organization . The information is given in the order you might see it if you were there.

Sample Paragraph 4

• There are three types of family vehicles made in the United States. The first type is the minivan. All American car manufacturers make a version of the minivan. Some say that the comfort and amenities of the minivan compare to none. The second type of family vehicle is the SUV. Some SUVs offer four-wheel-drive to navigate tough terrains, and they also offer seating for a large crowd. A third type of family vehicles is called the crossover. These vehicles supposedly have the best features of the sedan, minivan, and SUV. They are easy to maneuver, look much like a regular sedan, and sit up to six people. All of these vehicles are family friendly; they offer safety, roomy comfort, and many extra features to accommodate the special needs of families.

This paragraph shows another way to organize the details of a topic. The topic sentence of this paragraph is structured differently than the previous ones. Typically, the topic of a sentence is also the grammatical subject, but the subject in this sentence is “there,” a pronoun, and the topic that tells what the paragraph is about, “family vehicles,” is in the predicate of the sentence. The controlling idea is that there are three types made in the U.S.

The paragraph is organized according to those three types: the first type, the second type, and the third type. To conclude, there is a comment about “all of these vehicles” or all of these types of vehicles. When information is organized by types or features, the information is classified. This type of organization is classification .

Sample Paragraph 5

• Although the twin brothers share many physical characteristics, they handle themselves differently in social situations. Mario is a shy introverted young man. He has few friends and mostly keeps to himself. On the other hand, Gino is outgoing and the life of the party. Unlike Mario, Gino has many friends and feels totally at ease among big crowds. The best way to tell these identical twins apart is to invite both to a party and observe how differently they interact with the other guests.

When the topic sentence is complex (having more than one clause) as in this paragraph, there may be two subjects and therefore two topics; however, here, the subject of the first clause is “the twin brothers” and the subject for the second clause is “they,” so both subjects refer to the same topic—the twin brothers. The controlling idea is that the twin brothers share many physical characteristics but handle themselves differently socially.

The paragraph then progresses with descriptions of these similarities and differences. Contrast is created by signal phrases and words such as “although, “on the other hand,” and “unlike.” Words such as “apart” and “differently” also indicate that the organizational pattern of this paragraph is comparison and contrast .

Sample Paragraph 6

• There are many reasons why I enjoy walking tours when visiting new cities. For starters, walking through a city allows the visitor to see the details of an area without having to hurry. This often results in meeting locals and experiencing their lives and traditions first hand. Furthermore, walking tours are flexible and inexpensive because there are no strict schedules or transportation expenses. Travelers taking walking tours are rewarded with firsthand experiences in the places they visit and the opportunity to personally interact with the people who live there.

Because the first sentence begins with “there are,” the reader must move beyond the subject and verb to find the topic. Additionally, this is a complex sentence with an independent and dependent clause connected by “why,” so there may be two topics. Looking at the objects of both clauses, the reader finds “many reasons” and “walking tours.” These two topics are linked together by the controlling idea: the writer enjoys walking tours while visiting new cities for many different reasons.

The signal words build on this idea of “why” with terms such as “results” and “because.” The last sentence then sums up the ultimate effect of walking tours: Travelers are rewarded. This is an example of cause and effect organization.

Sample Paragraph 7

• Hiking can be especially exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is 6,684 feet above sea level. We first crossed a footbridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

In the first sentence, the topic of the paragraph is “hiking,” and the comment or main idea is that it “can be especially exhilarating during snowy winter months.” Based on this, the reader can expect supporting details to illustrate this exhilaration, but they do not know how it is organized until they look at the signal words that help progress the topic from one idea to the next.

Taking inventory of the signal words, the reader will find several time markers: “When” and “last January” set the narrative in the past while “first” and “then” develop a chronological order of events. The final summarizing sentence about hiking “in winter” reminds the reader of the season.

Within this chronology , signal words are associated with spatial organization: “over,” “up,” “beneath,” “through,” “crunched” (sounded), “saw,” “feels,” and “seeing.” Narratives typically include descriptive elements about the setting. Additionally, the concluding thought contrasts “inhaling” to “exhaling.” The reader can thus conclude that this paragraph has multiple patterns of organization that are intricately connected.

Topic Sentence

I. what is a topic sentence.

A topic sentence in a paragraph is like the GPS in a car. It shows you (and others) where you are going and explains the point of the paragraph. Everything else is used as supporting details. The topic sentence contains two parts: the topic and a controlling idea. The topic is WHAT the paragraph is going to be about, and the controlling idea explains WHY the paragraph is being written. The topic sentence helps your reader understand the purpose of your paragraph.

II. Examples of a Topic Sentence

The purpose of your paragraph will be made clear in your topic sentence. The most common reasons for writing are to persuade, to inform, and to entertain. It is also possible that a sentence could do more than one of these.

You will often use a persuasive topic sentence when writing for school, such as in literary essays .

The character Pip in the novel Great Expectations learns the importance of loyalty through his        interactions with the convict Abel Magwitch.

An informative topic sentence is often found in scientific articles.

White blood cells help fight infections by attacking bacteria, viruses and germs that invade the         body.

Topic sentences that entertain are sometimes found in magazines or other less formal writing.

It’s not hard to raise a bad child if you follow these simple instructions.

III. Parts of a Topic Sentence

There are just two parts in a topic sentence, the topic and the controlling idea. The topic is WHAT the paragraph is about, and the controlling idea explains WHY you are writing the paragraph. In the examples below, the topic is in orange and the controlling idea is in green .

Joseph loves to spend time with his friends .

What/who is this paragraph about? Joseph. Why is this paragraph being written? To explain something that Joseph loves to do.

Disneyland is the happiest place on Earth .

What/who is this paragraph about? Disneyland. Why is it being written? To show why Disneyland is the happiest place on Earth.

IV. Placement of Topic Sentences

A. initial placement.

The most common place for a topic sentence is at the beginning of the paragraph because it explains what the paragraph is going to discuss. The initial placement helps the writer organize the paragraph and tells the reader what to expect right in the beginning.

The best things in life are free . Although most people work hard to buy a good home or a nice car, those are not the things that they care about the most. At the end of their lives, they don’t want to hug their cars, or the walls of their fine houses. They want to be surrounded by the people they care about and who care about them. Kindness is free. Love is free. Friendship is free (or at least it should be!). Of course it is important to make money to survive, but love is important to live happily.

b. Final Placement

Sometimes the topic sentence is at the end of the paragraph, especially when the paragraph is a narrative or a mysterious story. Placing it at the end creates suspense or sometimes works to tell the point of the story.

The wealthy man was dying. He called for his friends and family to be near him and placed a hand on each one’s shoulder. They cried because they would miss him, and he cried because he had no more time to share with them. The beautiful things that he’d purchased over the years held no meaning. He didn’t care about his diamonds or his yacht or his large home. He cared for his children and the love they shared. They were here with him now and held his hands. He was glad he’d learned the most important lesson in life: the best things in life are free .

c. Medial Placement

The last place, the least common place for a topic sentence, is in the middle of the paragraph. The medial topic sentence usually functions as a transition between two ideas or details.  This works when you want to show that there are two (sometimes opposite) points to an issue, but the one you are arguing, the second point, is stronger, more specific, or more important. This topic sentence is generally introduced with a transition signal.

You can’t survive on love alone. People need money for basic necessities: food, shelter and clothing. Without money, life would be uncomfortable and difficult. However, time and energy should not be completely spent on making money because the best things in life are free . Having fun with friends and family is more important and more satisfying than buying a new car or nice clothes. People provide warmth, affection, understanding, and most of all, love. Money can’t love you back, and it does not guarantee happiness. Some of the richest people in the world are miserable, while some of the poorest people in the world are happy because they have the simple joy of loving people in their lives.  

V. How to Write a Topic Sentence

A. the best way to write your topic sentence is to consider why you are writing the paragraph.

• Decide on your reason for writing the paragraph
• After you have figured that out, write down the important details you want to include and see what they all have in common.
• Summarize the details into one sentence.

For example, if you want to write about your favorite movie, think about all the reasons that you like it. Is it funny? Exciting? Dramatic? Romantic? Be sure not to include too many things or else you will end up with an essay instead of a simple sentence. Once you have decided on your details, you are ready to write the topic sentence.

Here’s an example, the topic will be in orange and the controlling idea will be in green :

The best movie ever made was “Star Wars: the Force Awakens” because it was exciting and surprising .

An important point to remember is that the topic sentence should contain all relevant information that’s going to be in the paragraph. There should be no information about romance or comedy. It should only talk about what made the movie exciting.

b. Mistakes to Avoid

One of the biggest problems students face is keeping a paragraph or essay on topic. Sometimes they will write a good topic sentence but halfway through the paragraph, they think of another good idea and follow that. Without revision and editing, the topic sentence will not serve its purpose in the paragraph.

The best vacation I ever had was in Hawaii. The beaches were so beautiful and clean that swimming in them was like a dream . I especially loved the Waikiki beach. At night, there were free shows with dancers and live music. The music was so good that it made me want to dance. Dancing is my favorite thing to do in the world. When I was young, I studied ballet and tap dance. I’m thinking about taking it back up again. I might even study hip-hop!

The paragraph started out with Hawaii and end up with hip-hop dancing. You can see how the writer’s train of thought began to wander in the seventh sentence. With a different topic sentence, it would be possible to save this paragraph. Consider how different the direction would be with the following topic sentence.

The best vacation I ever had was in Hawaii. I especially loved the Waikiki beach. At night, there were free shows with dancers and live music. The music was so good that it made me want to dance and reminded me that dancing is my favorite activity in the world. In fact, when I was young, I studied ballet and tap dance. The dancing that I saw in Hawaii inspired me to get back into dancing . I might even study hip-hop!

With this new topic sentence, the second sentence would have to be eliminated or changed a bit. You can see how easy it is to get off-topic, but with a good topic sentence, and constant reference back to it, you are less likely to have that problem.

VI. So remember

• A topic sentence needs to contain the topic of your paragraph and a controlling idea.
• Everything in the paragraph should be connected to the topic sentence.
• The placement of the topic sentence depends on the type of paragraph.

VII. Exercises

Each of the paragraphs in this exercise has three possible topic sentences following it. Choose the best one and make sure that it includes the main idea of the paragraph.

1. _____________________________________________. In fact, he usually shows up five minutes early everywhere he goes. Because he’s so considerate, he hates to keep people waiting. He also believes that being early creates a better expereince. One time, when we were going to a movie together, John arrived thirty minutes earlier just so he could get the best seats in the theatre. I’m glad to have such a punctual friend.

a. John loves going to the movies.

b. John is always on time.

c. John hates to be kept waiting.

2. _________________________________________. The place is never crowded, but the service is still terrible. It seems like the staff has better things to do than wait on customers. Once I waited ten minutes just to buy a slice of pizza, and I was the only person in the whole store! I recommend staying away from Billy Bob’s Pizzeria.

a. Billy Bob’s Pizzeria has the worst pizza.

b. Billy Bob’s Pizzeria is an unpopular place to eat.

c. Billy Bob’s Pizzeria has terrible customer service.

3. I walked slowly down the dark path, afraid of my own shadow. But the tug on the leash propelled me forward. Buck, my golden retriever, was determined to take the most deserted trails through the forest. I could hear unfamiliar noises on all sides and urged Buck to do his business quickly. Oh, why couldn’t he be toilet trained? That would be better for everyone! _____________________________________.

a. Buck is an inconsiderate dog.

b. I hate walking my dog at night.

c. The forest is a dangerous place to walk at night.

4. Generally speaking, zoos these days are losing popularity. Many people feel that it’s unfair to lock up wild animals to entertain humans. ________________________________ . Some zoos go to great lengths to build a good environment for its animals. The good zoos treat their animals well and provide opportunities for the public to learn about the natural world. The best zoos protect endangered species and raise awareness about animals and their habitats.

a. Zoos perform a valuable service to society and should be part of every person’s childhood memory.

b. Zoos are horrible places that should be shut down because it’s not humane to lock up wild animals.

c. Zoos that do their best to make a pleasant habitat for the animals can be a pleasant place to visit.

How to Write a Good Topic Sentence

Last Updated: June 26, 2024 Fact Checked

This article was co-authored by Megan Morgan, PhD . Megan Morgan is a Graduate Program Academic Advisor in the School of Public & International Affairs at the University of Georgia. She earned her PhD in English from the University of Georgia in 2015. There are 10 references cited in this article, which can be found at the bottom of the page.

Perfecting the skill of writing topic sentences is essential to successful writing. A topic sentence usually comes at the beginning of a paragraph and lets your reader know what to expect from each paragraph. Think of it as the preview for a movie or a headline in a newspaper, highlighting the “main point” that’s to come in that paragraph. [1] X Research source Make sure your topic sentences are up to par, and the rest of your writing will feel like a breeze.

Writing a Successful Topic Sentence

• Keep in mind that this is not an invitation to simply announce your topic. “Today I’m going to discuss the benefits of gardening” is not an effective topic sentence. You should be able to make your intentions clear without stating them explicitly.
• The topic sentence in this example states a clear direction (“health benefits of gardening”) that you can then elaborate on in your paragraph.

• Don’t write too vague or general an idea or you will never be able to discuss it in a single paragraph. This is too general: “The United States suffered a lot during the Civil War.”
• Don’t write too narrow of a statement. There’s nothing much to talk about then, because it’s probably a fact. This is too narrow: “Christmas trees are either cedars or firs."
• Instead, aim for a good balance: “Sherman’s destruction in the South during the Civil War also caused incredible suffering.” This is big enough to relate to the broader idea of an essay, but not so narrow that there’s nothing left to discuss.

• Describe a character. This can be a physical or emotional description.
• Use dialogue. If there is a relevant conversation that will attract your reader’s attention, consider using part of it to start your paragraph.
• Portray an emotion. Use the opening sentence to portray an emotion to your reader.
• Use detail. While you don’t want to write a run on sentence by creating too much detail, it’s a good idea to create interest using sensory language in your topic sentence.
• Avoid rhetorical questions. While you want your reader to formulate questions in his or her mind, you do not want to formulate the questions yourself.

• Avoid presenting only facts in your topic sentence. While facts may be interesting, they do not introduce the reader to your paragraph nor do they draw the reader in. If you wish to include a fact, also include your own input. For example, instead of writing “All dogs need food,” try “All dogs need regular care, including healthy food, and children are the best ones to do it.” Alternatively, save your facts to use as evidence in the body of your paragraph.

• Using transitional elements, such as “In addition” or “In contrast,” is a good way to show the relationship between your ideas.
• For example: “Although gardening has many health benefits, people still need to exercise caution when outside.” This topic sentence establishes a connection to the main idea of the previous paragraph (“health benefits of gardening”) and points to the direction of the new paragraph (“things to be cautious of”).

Planning Your Topic Sentences

• You don’t have to write a formal outline using Roman numerals and the like. Even a loose, idea-based outline can help you know what you want to discuss.

• A topic sentence, unlike a thesis statement, doesn’t have to present an argument. It can present a “preview” of what the paragraph will argue or discuss.

• For example, a topic sentence could look like this: “In addition, increasing funding for public roads in Jackson County will improve local residents’ quality of life.” The rest of the sentences in this paragraph would relate to the main idea of public roads and how they will help benefit local residents.
• This is not as successful a topic sentence: “Increased funding for public roads in Jackson County has decreased traffic by 20%.” While this is probably an interesting fact for your argument, it’s too narrow for a topic sentence. The topic sentence has to direct the whole paragraph.

Avoiding Common Problems

• Unless it is an opinion piece, avoid using ‘I’ in your topic sentences.

• Rather than stating something like “In the story, Amelia did many good things such as help out her friends, talk to her parents, and support her team at school” say something like “As a result of the many activities Amelia participated in, she was recognized for her positive influence on the community.”

Community Q&A

• Avoid using words like you or we because it implies you know the reader, which you don’t. Thanks Helpful 0 Not Helpful 0
• In formal writing, avoid contractions such as “don’t,” “can’t,” and “isn’t.” Also avoid other common contractions like “would’ve” and “could’ve” which are commonly used. Instead type them out to look like “do not,” “can not”, “is not”, “would have”, and “could have.” Thanks Helpful 0 Not Helpful 0

How to Write a Topic Sentence to Grab Readers’ Attention

Before you learn how to write a topic sentence, it is essential to give a clear definition of this term.

Definition of a topic sentence

A topic sentence is a sentence highlighting the subject in a paragraph and outlining the boundaries of the topic. It contains, as a rule, a word, phrase, or part of a sentence that requires distribution and specification in one way or another (giving details, examples, indicating the cause, effect, comparison, opposition, etc.).

Topic sentence structure

The topic sentence in a custom term paper has two main parts: the topic, and the controlling idea which limits the topic. In the topic sentence there should be no controlling ideas that are unrelated to each other. For example, the three parts of the following controlling idea are not related. It takes three separate paragraphs to fully reveal them:

Indie films are characterized by experimental techniques, low production costs, and provocative themes.

Here is how it would be better:

Independent films are characterized by experimental techniques.

How to write a good topic sentence

Any essay has a structure consisting of paragraphs. The sentences in a paragraph are united by one topic. For the writer and reader, it is important that this topic is indicated. Usually in the paragraph, there is a topic sentence that highlights the subject and outlines the boundaries of the topic in the paragraph.

If there is no topic sentence, it means that the topic of the previous paragraph continues to develop in the current paragraph. The main idea of the paragraph is then contained in a sentence, which is called the conceptual sentence. The sentences within the paragraph must be arranged in such a way that the conceptual sentence is positionally highlighted and underlined. The beginning and end of the paragraph are the perfect places to emphasize the main idea.

A paragraph may begin with a topic sentence and end with a conceptual one. However, most often we find paragraphs that use either a topic or conceptual sentence. Please note that in the introduction of an essay, you write a paragraph that begins with a topic sentence. In the main body and in the conclusion, write paragraphs with conceptual sentences.

Ways to present a topic or thought in paragraphs can be represented by the following most common techniques:

• Giving examples confirming the idea expressed in the topic sentence
• Comparing and contrasting
• Explanation of the thesis reflected in the topic or conceptual sentence
• Causal justification of the content of the topic sentence
• Definition of concepts introduced by the topic sentence
• Analogy – the distribution of the topic by pointing to the analog
• Selection from the events, phenomena, persons, actions, signs, etc., indicated in the topic sentence of the paragraph, with its subsequent detailing
• Formulation of a conclusion from the content of the topic sentence
• Question-answer method of presenting the topic sentence in a paragraph
• Complement of the thought reflected in the topic sentence of the paragraph
• Forcing, strengthening the topic of the paragraph
• Confirmation of the main idea of the paragraph
• The assumption that is not contrary to the meaning of the topic or conceptual sentence
• A reference to the condition of the realization or truth of the statement (negation) made in the topic sentence of the paragraph

There are 3 important things to keep in mind about a topic sentence.

• A topic sentence is usually a complete sentence. This means that it contains at least one subject and one predicate.
• A topic sentence contains both the topic and the controlling idea. It names the topic and limits this topic to one aspect, which can be fully disclosed within a single paragraph.
• The topic sentence is the most general statement in the paragraph, because only the main idea is expressed in it. It does not give any details. The topic sentence is like a menu item in a restaurant. When you order food, you want to know more about such an item as, for example, simply “salad.” You want to know in general what type of salad this is, such as a potato, green, or fruit salad, but you don’t need to know all the ingredients. Likewise, the reader wants to know in general what to expect from a paragraph, but he or she does not want to know all the details from the very first sentence.

Topic sentences examples

You will understand better how to write a topic sentence with the following examples:

• Air pollution is caused by the presence in the atmosphere of toxic substances, mainly produced by human activities.
• Effective leaders praise the work of their managers, the staff, the board, and local branches.
• The “greenhouse effect” is the warming that happens when certain gases in Earth’s atmosphere trap heat.
• If you are a dog owner, you probably already know just how awesome dogs are.

Julie Chrisley to be resentenced for bank fraud scheme, original prison time thrown out

"Chrisley Knows Best" star Julie Chrisley 's nearly six-year prison sentence has been thrown out after federal judges ruled that her case had insufficient evidence.

On Friday, judges from the 11th U.S. Circuit Court of Appeals found that the judge in Chrisley's 2022 trial miscalculated her sentence and did not find evidence proving her full involvement in the bank fraud scheme for which she was sentenced, according to documents obtained by USA TODAY.

The court of appeals upheld Chrisley, her husband Todd Chrisley and their accountant Peter Tarantino's convictions, but found the original trial judge miscalculated Julie Chrisley's sentence. She was held responsible for the entire fraud scheme, which began in 2006.

"The district court did not identify the evidence it relied on to hold Julie accountable for losses incurred before 2007, and we cannot independently find it in the record," the judges wrote in their unpublished opinion.

Julie Chrisley will be resentenced in a lower court.

"We're pleased that the Court agreed that Julie's sentence was improper, but we’re obviously disappointed that it rejected Todd's appeal," Julie and Todd Chrisley's lawyer Alex Little said in an emailed statement to USA TODAY Tuesday. "With this step behind us, we can now challenge the couple's convictions based on the illegal search that started the case."

He continued: "The family appreciates the continued support they've received throughout this process. And they're hopeful for more good news in the future."

The Chrisleys' daughter Savannah Chrisley shared an update on the case in an Instagram video on Friday.

"Didn't necessarily go as we hoped," she said. "But we do have a little win."

The 26-year-old added that she is a "firm believer" that her mother would be able to come home "sooner rather than later."

"Please just be prayerful," she continued. "And I have some other ideas up my sleeve to get dad home."

In April,  Todd Chrisley was ordered to pay $755,000 to a former Georgia Department of Revenue investigator who sued him for defamation in 2021.

A Georgia jury found Todd Chrisley liable for defamatory statements against Amy Doherty-Heinze that he shared on his podcast and social media accounts, according to court documents obtained by USA TODAY.

Todd is currently serving a 10-year prison sentence for his role in the bank fraud and tax evasion scheme, reduced from his original 12-year sentence .

In January, the family's legal team announced Todd and Julie Chrisley would receive a $1 million settlement from the state of Georgia to resolve a 2019 lawsuit the couple filed against a former state tax official.

The first debate was a complete disaster for Joe Biden

• Joe Biden and Donald Trump met for their first debate of 2024 on Thursday.
• It was a total disaster for Biden, owing to his visibly frail performance.
• Trump was able to capitalize on it, appearing relatively calm and in command.

Joe Biden and Donald Trump met for their first debate of the year on Thursday.

It was a high-stakes gamble for the president, who has consistently trailed the former president in both national and swing state polls.

It went horribly.

Biden started off especially weak

From the very beginning of the debate, there was an unmistakable frailty to Biden's demeanor. According to NBC , he has a cold.

Responding to the CNN moderator Jake Tapper's first question, which was about the economy, Biden appeared out of breath. He hastily began reciting facts while slurring and occasionally omitting words.

At times, Biden uttered nonsensical phrases.

On another question about the war in Gaza, Biden flubbed, saying, "We are the biggest producer of support for Israel of anyone in the world."

During another question about the national debt, Biden inexplicably concluded by saying "We finally beat Medicare."

"Well, he's right," Trump responded. "He did beat Medicare. He beat it to death."

Trump, for his part, effectively capitalized on Biden's weak performance, maintaining a calm demeanor and staying disciplined while occasionally making jabs at the president.

Biden grew more energetic over time — but his responses remained muddled

Over the course of the debate, Biden's voice grew slightly less hoarse. But the incoherence in many of his responses remained.

Many Republican elected officials went into tonight claiming that Biden would be on drugs , anticipating that the president would deliver a relatively strong performance.

They ended up being wrong — but in a way that worked to their benefit.

Trump told plenty of lies. But Biden's poor performance overshadowed that.

Even as the former president maintained a relatively even keel at the debate, he told a litany of lies.

He falsely blamed Biden for the numerous indictments he's facing: Two of them were brought by local officials in New York and Georgia, while two others originated from the Justice Department, which operates independently of the president.

Trump claimed that food prices have "doubled and tripled and quadrupled" under Biden, a gross exaggeration of the 25% increase from 2019 to 2023 , according to the Department of Agriculture.

He also claimed Biden used the phrase "super predators" to describe African Americans, even though there's no record of the president making those comments.

It hardly ended up mattering: Biden's poor performance outshined all of it.

There's another debate on September 10. Biden will have to think hard about whether to do it.

Both Biden and Trump have agreed to another debate on September 10.

If you're a Biden ally, there's a few different ways to look at that: It could be an opportunity to reset what is obviously a very bad impression that was set tonight, or it could be yet another forum for Biden to show weakness.

Thursday's debate was the earliest general election debate on record: though both men are the presumptive nominees of their respective parties, they have yet to be officially nominated.

There are several other Democrats who have long been seen as potential Biden alternatives, should he choose to drop out.

But it's unclear if the president would opt to do so, or whether he'll face such calls from within his party.

There's also the potential for a chaotic convention in August if the party has to choose a new nominee, given nthe ideological divisions within the party.

After the debate, former senior Obama White House advisor David Axelrod, who reportedly triggered Biden's ire in the past over raising questions about the president's standing, was unrelenting in his analysis.

"I think there was a sense of shock actually on how he came out at the beginning of this debate," Axelrod said on CNN, while trying to give Biden some credit for addressing issues like abortion, "how his voice sounded — he seemed a little disoriented at the beginning of the debate. He did get stronger as the debate went on, but by that time, I think the panic had set in."

Axelrod agreed with other CNN panelists that there will now be discussions on whether Biden should step aside.
