Paragraphs & Topic Sentences

A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Paragraphs can contain many different kinds of information. A paragraph could contain a series of brief examples or a single long illustration of a general point. It might describe a place, character, or process; narrate a series of events; compare or contrast two or more things; classify items into categories; or describe causes and effects. Regardless of the kind of information they contain, all paragraphs share certain characteristics. One of the most important of these is a topic sentence.


A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.

Although most paragraphs should have a topic sentence, there are a few situations when a paragraph might not need a topic sentence. For example, you might be able to omit a topic sentence in a paragraph that narrates a series of events, if a paragraph continues developing an idea that you introduced (with a topic sentence) in the previous paragraph, or if all the sentences and details in a paragraph clearly refer—perhaps indirectly—to a main point. The vast majority of your paragraphs, however, should have a topic sentence.


Most paragraphs in an essay have a three-part structure—introduction, body, and conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating your meaning to your reader.

Introduction: the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body: follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion: the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea.

The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.

SCIENTISTS HAVE LEARNED TO SUPPLEMENT THE SENSE OF SIGHT IN NUMEROUS WAYS. In front of the tiny pupil of the eye they put, on Mount Palomar, a great monocle 200 inches in diameter, and with it see 2000 times farther into the depths of space. Or they look through a small pair of lenses arranged as a microscope into a drop of water or blood, and magnify by as much as 2000 diameters the living creatures there, many of which are among man’s most dangerous enemies. Or, if we want to see distant happenings on earth, they use some of the previously wasted electromagnetic waves to carry television images which they re-create as light by whipping tiny crystals on a screen with electrons in a vacuum. Or they can bring happenings of long ago and far away as colored motion pictures, by arranging silver atoms and color-absorbing molecules to force light waves into the patterns of original reality. Or if we want to see into the center of a steel casting or the chest of an injured child, they send the information on a beam of penetrating short-wave X rays, and then convert it back into images we can see on a screen or photograph. THUS ALMOST EVERY TYPE OF ELECTROMAGNETIC RADIATION YET DISCOVERED HAS BEEN USED TO EXTEND OUR SENSE OF SIGHT IN SOME WAY.

George Harrison, “Faith and the Scientist”


In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.

Along with the smooth flow of sentences, a paragraph’s coherence may also be related to its length. If you have written a very long paragraph, one that fills a double-spaced typed page, for example, you should check it carefully to see if it should start a new paragraph where the original paragraph wanders from its controlling idea. On the other hand, if a paragraph is very short (only one or two sentences, perhaps), you may need to develop its controlling idea more thoroughly, or combine it with another paragraph.

A number of other techniques that you can use to establish coherence in paragraphs are described below.

Repeat key words or phrases. Particularly in paragraphs in which you define or identify an important idea or theory, be consistent in how you refer to it. This consistency and repetition will bind the paragraph together and help your reader understand your definition or description.

Create parallel structures. Parallel structures are created by constructing two or more phrases or sentences that have the same grammatical structure and use the same parts of speech. By creating parallel structures you make your sentences clearer and easier to read. In addition, repeating a pattern in a series of consecutive sentences helps your reader see the connections between ideas. In the paragraph above about scientists and the sense of sight, several sentences in the body of the paragraph have been constructed in a parallel way. The parallel structures (which have been emphasized) help the reader see that the paragraph is organized as a set of examples of a general statement.

Be consistent in point of view, verb tense, and number. Consistency in point of view, verb tense, and number is a subtle but important aspect of coherence. If you shift from the more personal "you" to the impersonal “one,” from past to present tense, or from “a man” to “they,” for example, you make your paragraph less coherent. Such inconsistencies can also confuse your reader and make your argument more difficult to follow.

Use transition words or phrases between sentences and between paragraphs. Transitional expressions emphasize the relationships between ideas, so they help readers follow your train of thought or see connections that they might otherwise miss or misunderstand. The following paragraph shows how carefully chosen transitions (CAPITALIZED) lead the reader smoothly from the introduction to the conclusion of the paragraph.

I don’t wish to deny that the flattened, minuscule head of the large-bodied "stegosaurus" houses little brain from our subjective, top-heavy perspective, BUT I do wish to assert that we should not expect more of the beast. FIRST OF ALL, large animals have relatively smaller brains than related, small animals. The correlation of brain size with body size among kindred animals (all reptiles, all mammals, FOR EXAMPLE) is remarkably regular. AS we move from small to large animals, from mice to elephants or small lizards to Komodo dragons, brain size increases, BUT not so fast as body size. IN OTHER WORDS, bodies grow faster than brains, AND large animals have low ratios of brain weight to body weight. IN FACT, brains grow only about two-thirds as fast as bodies. SINCE we have no reason to believe that large animals are consistently stupider than their smaller relatives, we must conclude that large animals require relatively less brain to do as well as smaller animals. IF we do not recognize this relationship, we are likely to underestimate the mental power of very large animals, dinosaurs in particular.

Paragraph Transitions

Paragraphs represent the basic unit of composition: one idea, one paragraph. However, to present a clear, unified train of thought to your readers, you must make sure each paragraph follows the one before it and leads to the one after it through clear, logical transitions. Keep in mind that adequate transitions cannot simply be added to the essay without planning.  Without a good reason for the sequence of your paragraphs, no transition will help you.  Transitions can be made with particular words and phrases created for that purpose--conjunctive adverbs and transitional phrases--or they can be implied through a conceptual link.

Conjunctive Adverbs and Transitional Phrases

Conjunctive adverbs modify entire sentences in order to relate them to preceding sentences or paragraphs; good academic writers use many of them, but not so many that they overload the page. Here is a list of some of them, courtesy of The Brief Holt Handbook:


Transitional phrases can perform the same function:

in addition
in contrast
for example
for instance
of course
as a result 
in other words
as a result

Use them wisely and sparingly, and never use one without knowing its precise meaning.

Implied or Conceptual Transitions

Not every paragraph transition requires a conjunctive adverb or transitional phrase; often, your logic will appear through a word or concept common to the last sentence of the preceding paragraph and the topic sentence of the following paragraph. For example, the end of a paragraph by Bruce Catton uses a demonstrative adjective, "these," to modify the subject of the topic sentence so that it will refer to a noun in the last sentence of the preceding paragraph:

When Ulysses S. Grant and Robert E. Lee met in the parlor of a modest house at Appomattox Court House, Virginia,...a great chapter in American life came to a close.

    These men were bringing the Civil War to its virtual finish.

In this transition by Kori Quintana in an article about radiation and health problems, the connection between the paragraphs resides in the common term of "my family":
What I did not know when I began researching the connection between radioactivity and genetic damage was that I would find the probably cause of my own family's battle with cancer and other health problems.

    Hailing from Utah, the state known for its Mormon population's healthy lifestyle, my family has been plagued with a number of seemingly unrelated health problems.

The first paragraph outlines the origins of Quintana's research into the connection between radiation exposure and disease, and ends with the revelation that her own family had been affected by radiation.  The next paragraph discusses her family's health history.  Each has its own singular purpose and topic, yet the first paragraph leads to the topic of the second through a common term.

Paragraph transitions can expand the range of discussion as well as narrow it with an example, as Quintana's transition does; this selection from an article by Deborah Cramer on the ecological impact of the fishing industry shows how a single instance of overfishing indicates a world-wide problem:

....The large yearly catches, peaking at 130 million pounds from the Gulf of Maine in 1942, wiped out the fishery.  It has yet to recover.

    The propensity to ravage the sea is by no means unique to New England.  The northern cod fishery in Canada is closed indefinitely.  In Newfoundland more than 20,000 fishermen and fish processors were abruptly put out of work in 1992 when the government shut down the Grand Banks...

Here, the transition alludes to the entire preceding section about New England fishing.  Although Cramer managed this transition in a single sentence, transitions between large sections of an essay sometimes require entire paragraphs to explain their logic.

Proofreading Paragraph Transitions

At some point in your editing process, look at the end of each paragraph and see how it connects to the first sentence of the paragraph following it.  If the connection seems missing or strained, improve the transition by clarifying your logic or rearranging the paragraphs.  Often, the best solution is cutting out a paragraph altogether, and replacing it with the right one.
