Developing Paragraphs That Effectively Use Topic Sentences, Supporting Ideas, and Transitions

Learning how to develop a good topic sentence is the first step toward writing a solid paragraph. Once you have composed your topic sentence, you have a guideline for the rest of the paragraph. To complete the paragraph, a writer must support the topic sentence with additional information and summarize the main point with a concluding sentence.

In order to construct a successful paragraph, be sure to include these necessary elements:

• Topic Sentences
• Introduce your evidence
• State your evidence
• Explain your evidence
• Summarize the points made in the paragraph
• Transition

This section identifies the three major structural parts of a paragraph and covers how to develop a paragraph using transitional words and phrases.

Identifying Parts of a Paragraph

An effective paragraph contains three main parts: a topic sentence, the body, and the concluding sentence. A topic sentence is often the first sentence of a paragraph. This chapter has already discussed its purpose—to express a main idea combined with the writer’s attitude about the subject. The body of the paragraph usually follows, containing supporting details.  Supporting sentences help explain, prove, or enhance the topic sentence. The concluding sentence is the last sentence in the paragraph. It reminds the reader of the main point by restating it in different words.

Read the following paragraph:

After reading the new TV guide this week I had just one thought—why are we still being bombarded with reality shows? This season, the plague of reality television 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, but if any of them are reading this blog—stop it! We’ve had enough reality television to last us a lifetime!

The first sentence of this paragraph is the topic sentence. It tells the reader 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. 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.

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.

Sometimes, the topic sentence appears in the middle of a paragraph. Read the following example. The topic sentence is underlined for you.

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.

Implied Topic Sentences

Some well-organized paragraphs do not contain a topic sentence at all. Instead of being directly stated, the main idea is implied in the content of the paragraph. Read the following example:

Although no single sentence in this paragraph states the main idea, the entire paragraph focuses on one concept—that Luella is extremely old. The topic sentence is thus implied rather than stated. This technique is often used in descriptive or narrative writing. Implied topic sentences work well if the writer has a firm idea of what he or she intends to say in the paragraph and sticks to it. However, a paragraph loses its effectiveness if an implied topic sentence is too subtle or the writer loses focus.

Supporting Sentences

If you think of a paragraph as a hamburger, the supporting sentences are the meat inside the bun. They make up the body of the paragraph by explaining, proving, or enhancing the controlling idea in the topic sentence. Most paragraphs contain three to six supporting sentences depending on the audience and purpose for writing. A supporting sentence usually offers one of the following:

• Reason

Sentence:  The refusal of the baby boom generation to retire is contributing to the current lack of available jobs.

• Fact

Sentence:  Many families now rely on older relatives to support them financially.

• Statistic

Sentence:  Nearly 10 percent of adults are currently unemployed in the United States.

• Quotation

Sentence:  “We will not allow this situation to continue,” stated Senator Johns.

• Example

Sentence:  Last year, Bill was asked to retire at the age of fifty-five.

The type of supporting sentence you choose will depend on what you are writing and why you are writing. For example, if you are attempting to persuade your audience to take a particular position you should rely on facts, statistics, and concrete examples, rather than personal opinions. Read the following example:

To find information for your supporting sentences, you might consider using one of the following sources:

• Reference book
• Encyclopedia
• Website
• Biography/autobiography
• Map
• Dictionary
• Newspaper/magazine
• Interview
• Previous experience
• Personal research

Explaining Evidence

Remember not to conclude your body paragraph with supporting evidence. Rather than assuming that the evidence you have provided speaks for itself, it is important to explain why that evidence proves or supports the key idea you present in your topic sentence and (ultimately) the claim you make in your thesis statement.

This explanation can appear in one or more of the following forms:

• Analysis
• Evaluation
• Relevance or significance
• Comparison or contrast
• Cause and effect
• Refutation or concession
• Suggested action or conclusion
• Proposal of further study
• Personal reaction

Try to avoid simply repeating the source material in a different way or using phrases like “This quote means” to begin your explanation. Keep in mind that your voice should control your essay and guide your audience to a greater understanding of the source material’s relevance to your claim.

Concluding Sentences

An effective concluding sentence draws together all the ideas you have raised in your paragraph. It reminds readers of the main point—the topic sentence—without restating it in exactly the same words. Using the hamburger example, the top bun (the topic sentence) and the bottom bun (the concluding sentence) are very similar. They frame the “meat” or body of the paragraph. Compare the topic sentence and concluding sentence from the previous example:

Notice the use of the synonyms advantages and benefits. The concluding sentence reiterates the idea that owning a hybrid is advantageous without using the exact same words. It also summarizes two examples of the advantages covered in the supporting sentences: low running costs and environmental benefits.

You should avoid introducing any new ideas into your concluding sentence. A conclusion is intended to provide the reader with a sense of completion. Introducing a subject that is not covered in the paragraph will confuse the reader and weaken your writing.

A concluding sentence may do any of the following:

• Restate the main idea

Example:  Childhood obesity is a growing problem in the United States.

• Summarize the key points in the paragraph

Example:  A lack of healthy choices, poor parenting, and an addiction to video games are among the many factors contributing to childhood obesity.

• Draw a conclusion based on the information in the paragraph

Example:  These statistics indicate that unless we take action, childhood obesity rates will continue to rise.

• Make a prediction, suggestion, or recommendation about the information in the paragraph

Example:  Based on this research, more than 60 percent of children in the United States will be morbidly obese by the year 2030 unless we take evasive action.

• Offer an additional observation about the controlling idea

Example:  Childhood obesity is an entirely preventable tragedy.
