topic sentence examples

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鈥檙e 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鈥檚 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鈥檚 there to help you 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鈥檙e about to write an essay, you won鈥檛 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鈥檚 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鈥檚 safe to assume that the topic sentence belongs at the very beginning of the paragraph.

Yet depending on the paragraph you鈥檙e working on, you can also place your 鈥渕ain鈥 topic sentence after an 鈥渋ntro鈥 topic sentence. Let鈥檚 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 鈥渟afer鈥 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 鈥渟afer鈥 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鈥檛 want to say too much. Why?

You don鈥檛 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鈥檚 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鈥檚 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鈥檝e 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鈥檙e trying to introduce a bigger argument to serve your essay.

Let鈥檚 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鈥 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鈥 StatShot program states that in April sales over a year there has been an 18% increase.
