How to write a good topic sentence

On the surface, the purpose of a topic sentence is merely to present the main idea of the paragraph so that the reader knows what to expect. However, the best topic sentences do a little more. 

First, topic sentences string together paragraphs in a way that progresses nicely and facilitates reading. Moving from one paragraph to another can feel jarring and abrupt, so topic sentences help maintain the flow of the overall piece of writing—and readers’ focus as a result. 

Moreover, topic sentences also “preview” what the reader can expect from the rest of the paragraph. Based on the topic sentence, the reader can figure out if the paragraph will contain a list, statistical data, anecdotal evidence, persuasive opinions, a narrative, or something else. 

If the same paragraph covers opposing points of view, you may need two or more topic sentences to show the reader the main idea has changed. The most common example of this is in paragraphs that compare or contrast positions, in which case each perspective needs its own introduction . 

For these types of paragraphs , you could introduce your first idea with the opening topic sentence, then provide one or two sentences of support, and afterward introduce a second topic sentence known as a pivot (explained below). The pivot topic sentence introduces the paragraph’s second main idea or contradicting point of view, also followed by one or two sentences of support. 

Different types of essays use topic sentences differently as well.  Argumentative essays and  persuasive essays may have more opinionated topic sentences, whereas those in expository essays would stick to facts. Compare-and-contrast essays , which alternate between opposite sides of a topic, rely on topic sentences to ease those transitions, on top of everything else. 

This is true not just for different essay types, but also  different paragraph types as well. Even within the same essay, the author may switch up paragraph styles between expository, descriptive, persuasive, and narrative —in that case, each requires a slightly different style of topic sentence. 

Topic sentence vs. thesis statement

If you’re also learning about  how to write a thesis paper , you may get topic sentences confused with thesis statements. Basically, topic sentences introduce the main idea of a paragraph, whereas thesis statements introduce the main idea of the entire paper or essay. Both serve the same function—preparing the reader with a preview—but in different capacities.  

Topic sentence types and examples 

Before you learn how to write a topic sentence, it helps to see what different forms they can take. Here we explain the different types, along with some topic sentence examples. 

Simple statement

This is the most basic type of topic sentence, in which the author makes a general statement that the rest of the paragraph elaborates on. 

New research indicates a link between a person’s cognitive style and the type of content they post on Twitter. 

Those weeks at the farmhouse gave me some of the best memories of my life. 

To break up the monotony of using the same sentence types over and over again, you can phrase your topic sentences as direct commands or requests to your readers. 

Take a look at the data to see what I mean. 

Now let’s consider the alternative. 

Question (interrogative) 

Opening a paragraph with a question is a great way to get the reader interested and involved, as long as you stay on topic. 

What would you do if you became a millionaire overnight?

How many countries are prepared for a change in sea levels?  

If you have a complicated topic that covers multiple ideas, you may want to use a complex topic sentence. Even though these would still qualify as “statements,” they address more than one main idea. 

Although the majority of people still believe in alpha wolf theory, the truth is that wolf packs in nature don’t necessarily have a designated leader. 

As appealing as Ayn Rand’s ideas may seem to some, the logical and evidential support just isn’t there. 

Purely transitional

While all topic sentences have to deal with transitions to a degree, in some cases they can be purely transitional. These work best in circumstances when the topic changes drastically by drawing attention to the switch. 

However, not everyone agrees.

This was just the way the world was, and perhaps always would have been, if a random apple had not fallen onto the head of a young Isaac Newton. 

Similar to purely transitional sentences, pivot sentences are embedded within a paragraph— not at the beginning—to indicate a shift from one topic to another. They often include conjunctive adverbs such as however , meanwhile , furthermore , etc. 

By contrast, Nikola Tesla saw alternating current as a better solution. 

However, the Bears’ winning streak could not last forever. 

Topic sentences follow many of the usual  guidelines for writing sentences , but there are a few particular tips just for them. 

1 Get the reader interested with a hook

Good topic sentences usually include a “hook,” or something that makes people want to read more. While some are more common than others,  you can hook your readers in a variety of ways: 

• Shocking revelations , like surprising facts or impressive data

Despite the record-breaking turnouts, only one percent of the teams managed to complete the first challenge. 

• Mystery , which is especially useful with interrogative topic sentences

What finally changed the senator’s mind? 

• Emotion , or encouraging the reader to form a personal connection with the topic

Living with a dog has its difficulties, but not as many as living without one. 

2 Find a middle ground between general and specific

One of the biggest challenges in writing topic sentences is learning how much to include and how much to save for the rest of the paragraph. In short, you want to say just enough so that the reader knows what the paragraph is about, and ideally gets interested. Everything else should wait until the supporting sentences. 

For example, let’s look at a topic sentence for a paragraph about an apartment, from Meghan Daum’s essay “ My Misspent Youth ”: 

There was nothing particularly fancy about the place. 

The remaining paragraph is full of specific details about the apartment, but Daum doesn’t mention them in the opening sentence. Likewise, she doesn’t ignore the description altogether, giving a glimpse to the reader to pique their curiosity and prepare them for a paragraph describing the place. 

3 Be clear above all

The most important part of topic sentences is clarity. Even if you get the reader excited and eager to read more, it won’t matter if they don’t know what they’re reading about. 

This may be easy enough when just writing a single topic sentence, but it gets harder when writing sentence after sentence for hours on end. After a while, you get bogged down by your own thoughts and concerns about the essay and may momentarily forget about the reader’s perspective.

Examples of Topic Sentences That Make the Purpose Clear

What is a 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 formal writing, the topic sentence is usually the first sentence in a paragraph (although it doesn't have to be). Keep reading for the two main parts of a topic sentence as well as topic sentence examples in different subjects.

Topic Sentences and Controlling Ideas

Topic sentences introduce a paragraph and connect to an essay's thesis statement , which is the topic sentence of your entire essay . Every topic sentence has two parts: a topic (what the paragraph is about) and a controlling idea (the direction the paragraph will take). Take a look at these topic sentence examples in which the topic is bold and the controlling idea is in italics.

• Cats are very good pets for several reasons .
• Our school's dress code policy has many negative consequences for girls .
• The world population is strongly impacted by a lack of access to water .

The topic tells your audience what the paragraph will be about and connects to the thesis. The controlling idea tells them how you will explain it in this particular paragraph.

Topic Sentence Examples

Now that you know the main parts of a topic sentence, take a look at how they look in different subjects. Note that each example includes both a topic and a controlling idea.

• 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 as a result of systemic discrimination.
• The topic is "crime in poverty-stricken areas" and the controlling idea is "systemic discrimination."

Examples of Topic Sentences as Transitions

Skillful writers use topic sentences to both introduce their paragraph and to transition from the previous paragraph . Topic sentences as transitions help the essay feel smoother and more cohesive to the reader.

Examples of topic sentences as transitions include:

• Another way to reduce teen pregnancy rates is improved education.
• In addition to needing the correct tools, cooking requires a number of different skills.
• While purchasing real estate can be a good investment, it is important to be ready before buying a house.
• Likewise, graduating from high school is important for many different reasons.
• Even though having a baby can be a joyful event, having a first child is difficult because of the significant adjustments in your life.
• Because there are so many options out there, remodeling a kitchen requires research and a good eye.

Supporting Your Topic Sentence

Coming up with a strong topic sentence is one thing, but how do you support it? Using your topic sentence as a frame, you can then fill in the reasons or evidence you have outlined in your controlling idea. For example, a paragraph that supports a topic sentence might look like this:

Cats are very good pets for several reasons . They are naturally good caregivers because they take care of their kittens, so they want to take care of their owners as well. Cats are quite clean, and if you train them to use a litter box, they require almost no cleanup in their areas. Finally, cats are independent, so you don't need to worry about them being lonely when you're at school all day. They really are the ideal pet for almost any owner.

Notice how the writer provided three reasons to back up the phrase "several reasons" in the controlling idea. All three reasons related to the topic "cats are very good pets." Also, the last sentence in the paragraph connects directly back to the topic sentence (though you can also make this sentence a transition sentence into your next paragraph).

Staying on Topic

Remember that topic sentences set the tone for the paragraph and should relate back to the thesis or the main idea of the paper. A carefully thought-out topic sentence helps you, the author, to stay focused. It also gives readers the tools they need to clearly understand what you have to say.

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.

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.

How to Write Topic Sentences (Tips, Examples, Steps, and Starters)

You are probably wondering what goes into a topic sentence, why you must write a good topic sentence, and how topic sentences could transform your entire essay.

The truth is that students who have perfected the art of writing great topic sentences have always been successful in every piece of academic writing, such as essays, term papers, research papers, proposals, etc., that they undertake.

A well-polished topic sentence is crucial to your paragraphs. By reading the topic sentences, your professor or instructor can tell the grade that your paper will fetch.

Given that a topic sentence is like a headline to a news piece in a newspaper, whose purpose is to highlight what is to come in the paragraph, writing the best is inevitable.

Comparatively, a topic sentence is to a paragraph, what a thesis statement is to an essay, and what signposts are to whole sections in an essay or long paper. If we consider a paragraph a miniature essay, a topic sentence is a mini-thesis statement.

Let's explore every detail of the topic sentence to help you write topic sentences that will make your readers yearn to read more of your written pieces.

What is a Topic Sentence?

A topic sentence is the foremost sentence that appears in every paragraph. Its central role is to help organize the paragraph by summarizing the information in a paragraph. It expresses what the paragraph is about. Everything in the paragraph is anchored on the topic sentence.

The topic sentence comes first in terms of paragraph structure. Although it is always the first sentence, it can sometimes come after the transitional sentence.

When composing our guide to help you write masterful body paragraphs , we insisted on writing a perfect topic sentence to get higher grades for essays and papers. The topic sentence does many things. However, its main role is to state the paragraph's main point or controlling idea. It is akin to a mini-thesis in your body paragraphs. Let's see other roles it also plays.

A topic sentence does the following:

• Informs the readers/audience of the subject that is discussed in the paragraph
• Creates a sense of action
• Sets the focus of the paragraph
• Comprises the directing words and the topic
• It is never vague, too narrow or broad, and rambling
• Intrigues the readers to continue reading
• Asserts the point of view or attitude of the writer

What makes a good topic sentence?

Now that we know its roles or functions, let's look at the characteristics of a good topic sentence. Your topic sentence should strive to achieve these standards:

• It is a one-sentence statement indicating the paragraph's purpose, subject, or point.
• It is assertive and specific
• Introduces the topic in the paragraph
• Contains the central point and the topic of the paragraph
• It has a narrower focus than the thesis statement
• It appears in or near the first sentence of the paragraph
• It is the controlling idea for the paragraph
• Must relate to the thesis statement of your essay or paper
• It helps the readers to identify the major ideas fronted or discussed in the paragraph
• Contains one idea or multiple related ideas (complex topic sentence) that connect to the paragraph

If you are wondering how to start a topic sentence, you should understand that topic sentences begin with a simple statement that you then refine to reflect the content of your paragraphs. Generally, a good topic sentence is specific enough to give an idea of the focus of the specific paragraph but general enough that it does not give everything away.

Placement of a Topic Sentence

So, where does the topic sentence go in a paragraph? Must it be at the beginning? Let's find out.

Although many people think a topic statement must be the first sentence in the paragraph, it is not cast in stone.

It is a conventional writing practice that a topic sentence comes early to orient the reader to the paragraph's focus. However, you can occasionally place the topic sentence after a transition sentence to create continuity of ideas or related topics.

The transition sentence summarizes what was discussed in the previous paragraph; your topic sentence expresses the focus of the paragraph you are writing.

Topic sentence to begin a paragraph

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

Transition sentence and topic sentence in a paragraph

Example 1 : Undoubtedly, many people had seen the eventual growth of Bitcoin and cautioned others that it would be disastrous ( Transition sentence) . However, people who lost are those who were so much into the concept to take any pieces of advice ( Topic sentence)

The next sentence will discuss the characteristics of people who lost money in the Bitcoin crash.

Example 2 : Notably, Morrison succeeds in initiating the coming-of-age of female characters using spiritual and emotional bonds ( Transition Sentence ). In addition, the author uses the physical bonds of female friendship to propel her adolescent protagonists into self-awareness ( Topic Sentence) .

This sentence means that the coming paragraph delves into how the author uses physical bonds while the previous one discussed spiritual and emotional bonds.

Types of Topic Sentences to Use in Essays and Papers

Before we delve into how to write a topic sentence or the appropriate steps to take, it helps to have a discussion on the different forms a topic sentence can take. Let's look at the types and the respective examples of topic sentences.

Can topic sentences be used as transitions between paragraphs?

Yes, topic sentences can be used as transitions between paragraphs. They help build a flow of ideas by linking a paragraph from the previous one. When intending to use them as transitions, it is good to use transition or linking words as part of the topic sentence to vividly establish connections between the two ideas.

You can use them in various ways; we will cover each and give examples as necessary.

Compare and Contrast

When you intend to compare ideas in a paragraph with those in the preceding paragraph, or when presenting contrasting information, you can use words that highlight the difference.

You can use transitions such as however, on the other hand, yet, or in contrast.

Example: Although the costs of protecting the environment might be assumed to be high, the long-term benefits outweigh the cost.

Besides using transition words, you can also imply the contrast by formulating the topic sentence as a question.

Example: Is banning Bitcoin a solution, or are there other government-led strategies that can be used to control the cryptocurrency industry?

Emphasizing and Expanding

When a paragraph gives details or other examples of the same point, you can use words that imply similarity/emphasis, such as: for example, as an illustration, indeed, or in fact.

Example: Indeed, the Bitcoin industry has been flocked to and preferred by organized criminals who have managed to transact without being noticed by authorities.

Anticipating and Summarizing

When a paragraph shifts focus to a different aspect of the same subject, your topic sentence can sum up what was in the previous paragraph and anticipate what to expect in the new paragraph you are writing.

Example: While Bitcoin has strengthened global organized crime, the technology it is based on, blockchain technology, can be leveraged by governments for accountability, transparency, and sustainability of operations.

Examples of Good Topic Sentences

Let us now explore the examples of topic sentences, distinguishing between the two parts of a topic sentence: topic and controlling idea.

If you want to be a skillful writer, frame your topic sentence per the examples we have given above. The topic should tell your readers what the paragraph is about, while the controlling idea informs them of its direction. Topic sentences should set the tone of the paragraph and, at the same time, reflect on your paper's thesis or main idea.

How to write strong topic sentences in 5 steps

With your knowledge, let us now look at the steps you should take to write a perfect topic sentence. These steps will come in handy when writing an essay or paper. As explained below, you can write a good topic sentence in 5 steps.

1. Choose a good topic

When you select a good topic for your essay or paper, you can develop various topic sentences that support the topic with different ideas, as reflected in the paragraphs. Therefore, select a topic that is neither too narrow nor too broad yet interesting and practical.

2. Research widely for perspectives

After selecting the topic, ensure that you do some light preliminary research. Preliminary research will help you determine what scholars are saying about your topic.

Besides, you will also develop a perspective on the topic. And as you develop a perspective, you will have an idea of what the topic sentences, thesis, and paragraphs should look like.

For this step, you can use scholarly and non-scholarly resources because your main aim is to familiarize yourself with the chosen topic.

3. Write your thesis statement

As you research, you will know the points to address in your essay, especially the controlling or main idea, otherwise known as the thesis statement. Construct a thesis statement that is assertive, focused, and concise. It should determine your topic sentences.

4. Create an essay outline with draft topic sentences

After developing a thesis statement, create an outline as a roadmap for your essay or paper writing process. The outline will determine what points fall where and in what order.

Remember to specify the topic sentences for your body paragraphs when crafting the outline. Ensure that the topic sentences you have selected support your thesis.

You can refine the topic sentences as you write, so do not be so hard on yourself.

Writing the topic sentence follows the same guidelines as that writing sentences. However, there are a few deviations. We shall share more when exploring the tips to write topic sentences successfully.

5. Refine your topic sentence

After writing your topic sentences as a simple statement, in the beginning, revise them as you write or as you make discoveries on the topic. Ensure that each topic sentence matches the content in each paragraph.

Think of your topic sentences as signposts that tell readers the direction of your argument in the paragraph.

Ensure that there is a connection between the paragraphs for solid writing. And remember, you can use your topic sentences as transitions. When fine-tuning the topic sentences, ensure that they are clear and coherent. Anyone should understand them quickly and know what the paragraph is about. Also, use specific wording depending on the type of topic sentence you are writing.

Tips for Writing Appealing Topic Sentences

Apart from the steps discussed above, use the following tips to write topic sentences that make sense.

1. State the topic and controlling idea clearly

A topic sentence is most likely the first sentence in your paragraph and sometimes the second after a transition sentence. Regardless of order, ensure it states the topic and the controlling idea. Doing so makes your intention and direction in the paragraph known to your readers.

2. You should balance it between general and specific ideas

A topic sentence links your paragraph to your thesis statement. Therefore, you need to ensure that it balances broad and narrow ideas. Avoid vagueness or being too general when writing an idea. Never write a narrow statement but let it be a sentence with some sense of focus and direction.

3. You should hook your readers

A paragraph is a mini-essay; start by hooking your readers in the topic sentence. You can achieve this by describing a character, using a dialogue, stating a fact, using details or facts, portraying emotions, shocking revelations, or stating some mysteries to get the readers interested. Then, when you whet your readers' appetite, they automatically give in and read the entire paragraph.

4. Be concise

Good topic sentences are clear. Make sure that your topic sentences are brief. Make your intentions clear off the bat. You should frame the topic sentence to make it slightly more specific than the thesis statement.

A short, clear, and direct topic sentence creates a good flow. Only state, in your topic sentence, facts that can be substantiated or supported by concrete evidence

. You can use a reasonable opinion in your topic sentence. However, that should be the case if you can back up your claims through supporting sentences. Topic sentences are not limited to facts alone; you can use opinions if they can be substantiated. And as soon as you are ready with your essay, do a complete topic sentence reverse outline to assess whether they are strong, clear, and concise.

5. Use the topic sentence as a transition

We have already discussed using topic sentences as transitions in the examples and previous sections. First, guide your readers through your argument by connecting ideas when you use transition topic sentences. Then, when you use them as a bridge, you achieve some great flow that keeps your readers interested until the end.

6. Do not list information

Like in chess or poker, you should never lay all your cards or show your next move early. When writing topic sentences, avoid listing what to expect in the paragraph. Instead, give a snippet of what is to come in the paragraph. Avoid mentioning everything upfront because there is no need to read the entire paragraph.

7. Do not mention things you will not support

If you make any statement in the topic sentence, support it in the paragraph. Therefore, if you have no intention of examining any point further, let it slide. However, if you give facts, opinions, or both, ensure that your paragraph expounds on and expands on them.

8. Do not begin with quotes or rhetorical questions

You can use all the sentence starters and hooks but quotes and rhetorical questions. When a quote or question is fantastic, leave it out of the topic sentence preferences.

These are not your words; a topic sentence should include some of your opinions and not someone else's. Mainly, that is why we never have in-text citations on topic sentences.

When you realize that a quote is opinion-based, adopt its concept, and write your opinion. And if it is based on facts, save it for later in the paragraph and then expound it to support the topic sentence and the thesis.

Regarding the rhetorical question, let the readers formulate questions in their minds, not you. In a similar vein, avoid summarizing events in your topic sentences.

Topic Sentence Checklist

After you are done with writing your body paragraphs, you can use the checklist below to evaluate their effectiveness.

• Is the topic sentence the first statement in your sentence?
• Is the topic sentence coming after the transitional sentence? If so, does it fit perfectly?
• Is there a clear link between your topic sentence and the paper's thesis?
• Does the topic sentence have a topic and a controlling idea?
• Does the topic sentence reflect the scope of the paragraph without stating the exact facts?
• Is the topic sentence focused? Is your topic sentence precise, brief, yet thorough?

If yes to any of these, please proceed with your paper. If not, make the necessary adjustments.

Topic Sentence: Definition, Examples and Useful Tips for Writing A Topic Sentence

When writing, there are many aspects which we need to take into consideration. One such aspect is the topic sentence, but how do we use this? In this article, we are looking at what the topic sentence is and how it is used within a piece of writing . We are also going to be looking at a variety of examples to give us a better understanding of its function.

Topic Sentence

What Is A Topic Sentence?

Some might say that the topic sentence is one of the most important aspects and definitely the most vital sentence within a paragraph . In some cases, you might hear the topic sentence is referred to as the focus sentence but these are essentially the same thing.

A topic sentence is used to summarize all of the information within a paragraph. When writing in a more formal style, the topic sentence will usually feature at the beginning of the paragraph, although this is not a set rule.

What Is A Topic Sentence Used For?

A writer will use a topic sentence as a way of explaining to the audience what the paragraph is going to be about. Any sentences which appear after the topic sentence should give further information about the topic sentence or should give facts about it in order to prove the claim that it has made. The following sentences might also serve as a way to further describe the topic sentence by giving more details about it. For example, if the topic sentence is about animals kept as domestic pets, the following sentences should relate back to that subject.

On top of this, the topic sentence should always refer back to the thesis statement which was made at the beginning of the essay . You can imagine the thesis statement as being a map which directs the reader as to where you are going with the information and how it is being treated.

Controlling Ideas

When writing a topic sentence, each one should feature a controlling idea. This will serve as an indicator as to where the rest of the paragraph will go and what will be discussed.

Topic Sentences Examples

Now that we are clear on what a topic sentence is, we are going to take a look at some examples to further grow our understanding of them.

• ‘There are a lot of reasons why (name of a city) is the most polluted in the world.’

The controlling topic here is that there are ‘a lot of reasons’ and the topic is that a certain town is the most polluted.

• ‘In order to be an effective manager, one must have certain qualities.’

The topic of this sentence is being an effective manager and it has a controlling idea of ‘certain qualities.’

• ‘There are a lot of factors which contribute to global warming .’

This sentence has a topic of global warming whilst the controlling idea is related to ‘factors which contribute.’

• ‘We can improve teen pregnancy rates by improving education.’

The topic of this sentence in that teen pregnancy can be improved and the controlling idea is ‘improving education.’

How to Write A Topic Sentence

Write your thesis statement.

Before you can write a topic sentence, you must have a thesis statement. This should be strong and be effective in summing up the purpose of the essay as well as the main argument.

Outline Your Essay And Draft Out The Topic Sentences

The next step is to create your essay outline, this will give your essay structure and will allow you to detail what is going to be discussed in each paragraph. You will also make note of what data and evidence will be included in each of the paragraphs.

This is the point where you can play with words and draft up some topic sentences for each of your paragraphs. A topic sentence needs to be much more specific than your thesis statement but it should relate clearly to it.

Expand With Some Evidence

The remaining sentences within your paragraph should logically flow from the original topic sentence. They should be used to expand on what has been said in the topic sentence. This will not only make your workflow but will also ensure that each paragraph remains focused and relevant to the topic sentence. You should give some evidence to support your topic sentence.

Revise The Topic Sentences

What your topic sentence looks like to begin with may not be how it ends up in the final draft and that is OK. It is very important that you look over and edit each topic sentence within the essay as you go along. This will ensure that they remain relevant to the content of your paragraphs.

When making the final edits for your topic sentences, you should ensure that they are clear enough to allow the reader to know what the paragraph is going to be about but also not so clear that they detail everything you wish to talk about within that paragraph.

Transitions

Your topic sentence will sometimes serve as a transition between your paragraphs and in this case, they may do one of the following things:

• Compare and contrast
• Emphasize or expand

Conclusion:

A topic sentence is one which appears, usually (but not always) at the beginning of each paragraph of an essay. The topic sentence is used to layout the ideas and arguments that will be covered within the paragraph and should be carefully planned out to ensure that they are clear enough to give the reader an idea of what will be discussed but not to give away too much about the content of the paragraph. Your topic sentence may serve one of many purposes including summarizing and comparing.

How To Write A Strong Body Paragraph

Do your essays and papers lack clarity and structure? Are your readers left confused about your main points?

Many writers struggle with this issue, often because they overlook a critical element of essay writing: the topic sentence.

In this guide, we'll define what a topic sentence is, provide clear examples, and share valuable tips to help you write strong topic sentences.

Let’s get started!

• 1. What Is a Topic Sentence In An Essay? 
• 2. How to Write a Topic Sentence In Simple Steps
• 3. Types of Topic Sentences
• 4. Topic Sentences Examples 
• 5. Common Pitfalls in Crafting Topic Sentences

What Is a Topic Sentence In An Essay? 

In an essay , a topic sentence is the first sentence in a paragraph, and it gives us a sneak peek into what the paragraph will talk about. 

It is like a mini-thesis statement for a paragraph in an essay. It summarizes the main idea of the paragraph and tells the reader what to expect next. 

This sentence is important because it keeps your writing clear and organized, helping each paragraph contribute smoothly to your overall point or story.

What is the Purpose of a Topic Sentence?

The purpose of a topic sentence is to make your writing clear and organized. Think of it like this: if you're telling a story, you wouldn't jump from one topic to another without letting your friends know, right? That would be confusing!

Similarly, in writing, a topic sentence helps your reader know what to expect in each paragraph. It's like a mini-map for your essay. 

When you read the topic sentence, you instantly get a sense of what the paragraph will discuss.

Here's why topic sentences are important:

• Guiding the Reader: They help readers understand what each paragraph is about.
• Organizing Your Writing: Topic sentences keep your ideas clear and in order within each paragraph.
• Connecting Ideas: They smoothly link one paragraph to the next, ensuring your essay flows logically.
• Keeping You on Track: As a writer, topic sentences help define the focus point of each paragraph.

Where Is The Topic Sentence Placed?

The placement of a topic sentence in a paragraph is crucial for conveying the main idea and guiding the reader's understanding. 

Typically, the topic sentence is positioned at the beginning of a paragraph. This serves as a clear and concise statement that introduces the central theme or point that the rest of the paragraph will discuss and support. 

Topic Sentence vs. Thesis Statement

Understanding the difference between a topic sentence and a thesis statement is important for good writing. 

A topic sentence comes at the start of a body paragraph and tells the main idea of that paragraph. 

A thesis statement, found at the end of the essay introduction , sums up the main argument of the entire essay. While the topic sentence guides the reader through a specific paragraph, the thesis statement provides a roadmap for the whole essay. 

Both are key to creating clear and organized writing.

How to Write a Topic Sentence In Simple Steps

Writing an effective topic sentence is a skill that can significantly improve your writing. Follow these five precise steps to craft a compelling topic sentence:

• Revisit your essay outline
• Identify main idea of the paragraph
• Connect to the thesis
• Use transition words

Let's break down each of the four steps for writing a topic sentence in more detail:

Revisit Your Essay Outline

Start by reviewing your essay outline to understand the overall structure and flow of your argument. This helps ensure each paragraph fits cohesively within the larger framework of your essay.

Identify the Main Idea of the Paragraph

Determine the central point or idea you want to convey in the paragraph. Limit your topic sentence to addressing one main aspect or idea.

Resist the temptation to cover too much ground in a single sentence; this can lead to confusion and dilution of your message.

Connect to the Thesis

The topic sentence should reflect how this paragraph contributes to your overall argument or purpose.

Clearly establish how the paragraph's main idea supports or advances the broader argument presented in your thesis statement.

Use Transition Words

Incorporate transition words or phrases to link your topic sentence with the previous paragraph or to introduce a new idea. This helps maintain a smooth and logical flow in your writing.

Types of Topic Sentences

Understanding the various types of topic sentences can enhance your writing by providing different ways to introduce and develop your ideas. Here are some common types along with explanations and examples:

Simple Statement Topic Sentence

A simple statement topic sentence directly presents the main idea of the paragraph in a straightforward manner.

Example: "Exercise is essential for maintaining a healthy lifestyle."

This sentence clearly introduces the main idea that the paragraph will discuss the importance of exercise for health.

Question Topic Sentence

A question topic sentence engages the reader by posing a question that the paragraph will answer.

Example: "What are the benefits of regular exercise for mental health?"

This type of topic sentence piques the reader's curiosity and sets up the paragraph to provide answers and explanations.

Command Topic Sentence

A command topic sentence instructs or encourages the reader to consider or take action on a specific point.

Example: "Think about how daily exercise can improve your overall well-being."

This approach directs the reader’s attention and prepares them for detailed information that follows.

Transitional Topic Sentence

A transitional topic sentence helps to smoothly connect ideas between paragraphs, maintaining the flow of the essay.

Example: "While diet plays a crucial role in health, exercise is equally important for maintaining overall well-being."

This type of sentence links the previous paragraph about diet with the current paragraph about exercise, ensuring coherence.

Pivot Topic Sentence

A pivot topic sentence indicates a shift in direction or a contrasting idea within the essay.

Example: "However, despite the benefits of exercise, many people struggle to maintain a regular fitness routine."

This sentence signals a change in the discussion, preparing the reader for a new, contrasting idea that will be explored in the paragraph.

Topic Sentences Examples 

Here are five examples of topic sentences, along with their respective topics and controlling ideas:

• Topic: Climate change
• Controlling Idea: Growing threat to global ecosystems
• Topic: Time management skills
• Controlling Idea: academic success
• Topic: Benefits of regular exercise
• Controlling Idea: Extend beyond physical health
• Topic: Artificial intelligence
• Controlling Idea: reshaping the job market
• Topic: Digital marketing strategies
• Controlling Idea: Transforming business audience reach

Common Pitfalls in Crafting Topic Sentences

When writing a topic sentence, it's important to be aware of common pitfalls and things to avoid to ensure its effectiveness in your writing. 

Here are key things to steer clear of:

• Vagueness and Ambiguity: Avoid vague or unclear language. A topic sentence should clearly convey the main idea without confusing readers.
• Overly Broad Statements: Steer clear of broad statements. Focus on a specific aspect of the topic to maintain clarity.
• Lack of Connection: Ensure your topic sentence logically connects to the previous paragraph or the overall theme. Avoid abrupt transitions.
• Repetition: Don't restate the thesis or repeat information from the essay introduction. Use the topic sentence to introduce new ideas or aspects of your argument.
• Complexity: Avoid introducing overly complex ideas. Keep the topic sentence concise and straightforward.

In conclusion, writing effective topic sentences is a skill that can significantly improve your essays. By following the steps outlined in this guide, you can ensure that your topic sentences are clear, concise, and engaging.

What is the difference between a topic sentence and a thesis statement.

A topic sentence is a sentence found at the beginning of a paragraph and introduces the main point of that specific paragraph.

A thesis statement, on the other hand, is usually found in the introductory paragraph of an essay and presents the overall argument or main idea of the entire document.

Some good topic sentence starters include:

• "Additionally"
• "Furthermore"
• "In contrast"
• "On the other hand"
• "Conversely"
• "Nevertheless"
• "In conclusion"

These words can help you introduce and connect ideas between paragraphs and provide a smooth transition into the main point of each paragraph.

What are the 3 parts of a topic sentence?

A topic sentence typically consists of three main parts:

• Subject: The main idea or topic of the paragraph.
• Verb: The action or state of being related to the subject.
• Focus: Specific details that narrow down the main idea and indicate what the paragraph will discuss.

These components work together to provide a clear and concise introduction to the paragraph’s content.

How to write effective topic sentences

What is a topic sentence.

A topic sentence is:

• a sentence at the beginning of a paragraph
• that states or suggests the main idea (or topic) of a paragraph

In your critical essay, your topics sentences should:

• link to the essay task
• mention the technique or device you are going to analyse

Topic sentences in a basic essay

If you find writing topic sentences tricky, it might be helpful to prepare a bank of topic sentence stems or starters .

You can keep it simple to begin with:

• The first way in which…
• The second way in which…
• The third way in which…
• The fourth way in which…
• The final way in which…

Completing the topic sentence

Once you have the topic sentence stems, you just need to complete the sentence by adding:

• the words of the task – what is the question asking you to explore or analyse?
• the technique/aspect from the text that you will be focusing on in the specific paragraph

For example, the first two topic sentences in a basic critical essay on the theme of Shakespeare’s ‘Sonnet 18’ might look like this:

• The first way in which Shakespeare explores the theme of love is through word choice.
• The second way in which Shakespeare explores the theme of love is through extended metaphor.

This method can feel a bit mechanical. However, it will help you structure your response in a straightforward way.

Topic sentences in a developed essay

In a more developed essay, topic sentence stems might look like this:.

• The writer establishes …
• The writer develops …
• The writer further explores …
• The writer continues …
• The writer concludes …

These sentence starters are helpful to use because they:

• signpost to your marker that your line of argument is progressing and building
• demonstrate an understanding of the text as whole (you know what happens at the beginning , in the middle and at the end of the text)

Topic sentences in a detailed and insightful essay

You could start by referencing the poetic, literary, dramatic or filmic close filmic Relating to films or cinematography. device that you are going to be focusing on in the paragraph.

Examples of topic sentences in a detailed and insightful essay

• Shakespeare’s use of rhythm enhances the exploration of romantic love.
• The novelist’s choice of second person narration proves interesting in the exploration of the theme of loss.
• In the play’s turning point, the dramatist draws attention to the protagonist’s inner conflict.
• In the film’s opening scene, the director makes effective use of editing to establish the futuristic setting of the story.
