Placement of Topic Sentences

decorative imageA topic sentence can appear anywhere within a paragraph or can be implied (such as in narrative or descriptive writing). In college-level expository or persuasive writing, placing an explicit topic sentence at the beginning of each paragraph (the first or second sentence) makes it easier for readers to follow the essay and for writers to stay on topic, but writers should be aware of variations and maintain the flexibility to adapt to different writing projects.

The following examples illustrate varying locations for the topic sentence. In each example, the topic sentence is underlined.

Topic Sentence Begins the Paragraph (General to Specific)

After reading the new TV guide this week I wondered why we are still being bombarded with reality shows, a plague that continues to darken our airwaves. Along with the return of viewer favorites, we are to be cursed with yet another mindless creation. Prisoner follows the daily lives of eight suburban housewives who have chosen to be put in jail for the purposes of this fake psychological experiment. A preview for the first episode shows the usual tears and tantrums associated with reality television. I dread to think what producers will come up with next season and hope that other viewers will express their criticism. These producers must stop the constant stream of meaningless shows without plotlines. We’ve had enough reality television to last us a lifetime!

The first sentence tells readers that the paragraph will be about reality television shows, and it expresses the writer’s distaste for these shows through the use of the word bombarded. Each of the following sentences in the paragraph supports the topic sentence by providing further information about a specific reality television show and why the writer finds it unappealing. The final sentence is the concluding sentence. It reiterates the main point that viewers are bored with reality television shows by using different words from the topic sentence.

Paragraphs that begin with the topic sentence move from the general to the specific. They open with a general statement about a subject (reality shows) and then discuss specific examples (the reality show Prisoner). Most academic essays contain the topic sentence at the beginning of the first paragraph.

Topic Sentence Ends the Paragraph (Specific to General)

Last year, a cat traveled 130 miles to reach its family, who had moved to another state and had left their pet behind. Even though it had never been to their new home, the cat was able to track down its former owners. A dog in my neighborhood can predict when its master is about to have a seizure. It makes sure that he does not hurt himself during an epileptic fit. Compared to many animals, our own senses are almost dull.

The last sentence of this paragraph is the topic sentence. It draws on specific examples (a cat that tracked down its owners and a dog that can predict seizures) and then makes a general statement that draws a conclusion from these examples (animals’ senses are better than humans’). In this case, the supporting sentences are placed before the topic sentence and the concluding sentence is the same as the topic sentence. This technique is frequently used in persuasive writing. The writer produces detailed examples as evidence to back up his or her point, preparing the reader to accept the concluding topic sentence as the truth.

Topic Sentence in the Middle of the Paragraph

For many years, I suffered from severe anxiety every time I took an exam. Hours before the exam, my heart would begin pounding, my legs would shake, and sometimes I would become physically unable to move. Last year, I was referred to a specialist and finally found a way to control my anxiety—breathing exercises. It seems so simple, but by doing just a few breathing exercises a couple of hours before an exam, I gradually got my anxiety under control. The exercises help slow my heart rate and make me feel less anxious. Better yet, they require no pills, no equipment, and very little time. It’s amazing how just breathing correctly has helped me learn to manage my anxiety symptoms.

In this paragraph, the underlined sentence is the topic sentence. It expresses the main idea—that breathing exercises can help control anxiety. The preceding sentences enable the writer to build up to his main point (breathing exercises can help control anxiety) by using a personal anecdote (how he used to suffer from anxiety). The supporting sentences then expand on how breathing exercises help the writer by providing additional information. The last sentence is the concluding sentence and restates how breathing can help manage anxiety. Placing a topic sentence in the middle of a paragraph is often used in creative writing. If you notice that you have used a topic sentence in the middle of a paragraph in an academic essay, read through the paragraph carefully to make sure that it contains only one major topic.
