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.

Writing an essay often seems to be a dreaded task among students. Whether the essay is for a scholarship, a class, or maybe even a contest, many students often find the task overwhelming. While an essay is a large project, there are many steps a student can take that will help break down the task into manageable parts. Following this process is the easiest way to draft a successful essay, whatever its purpose might be.
According to Kathy Livingston’s Guide to Writing a Basic Essay, there are seven steps to writing a successful essay:
1. Pick a topic.
You may have your topic assigned, or you may be given free reign to write on the subject of your choice. If you are given the topic, you should think about the type of paper that you want to produce. Should it be a general overview of the subject or a specific analysis? Narrow your focus if necessary.
If you have not been assigned a topic, you have a little more work to do. However, this opportunity also gives you the advantage to choose a subject that is interesting or relevant to you. First, define your purpose. Is your essay to inform or persuade?
Once you have determined the purpose, you will need to do some research on topics that you find intriguing. Think about your life. What is it that interests you? Jot these subjects down.
Finally, evaluate your options. If your goal is to educate, choose a subject that you have already studied. If your goal is to persuade, choose a subject that you are passionate about. Whatever the mission of the essay, make sure that you are interested in your topic.
2. Prepare an outline or diagram of your ideas.
In order to write a successful essay, you must organize your thoughts. By taking what’s already in your head and putting it to paper, you are able to see connections and links between ideas more clearly. This structure serves as a foundation for your paper. Use either an outline or a diagram to jot down your ideas and organize them.
To create a diagram, write your topic in the middle of your page. Draw three to five lines branching off from this topic and write down your main ideas at the ends of these lines. Draw more lines off these main ideas and include any thoughts you may have on these ideas.
If you prefer to create an outline, write your topic at the top of the page. From there, begin to list your main ideas, leaving space under each one. In this space, make sure to list other smaller ideas that relate to each main idea. Doing this will allow you to see connections and will help you to write a more organized essay.
3. Write your thesis statement.
Now that you have chosen a topic and sorted your ideas into relevant categories, you must create a thesis statement. Your thesis statement tells the reader the point of your essay. Look at your outline or diagram. What are the main ideas?
Your thesis statement will have two parts. The first part states the topic, and the second part states the point of the essay. For instance, if you were writing about Bill Clinton and his impact on the United States, an appropriate thesis statement would be, “Bill Clinton has impacted the future of our country through his two consecutive terms as United States President.”
Another example of a thesis statement is this one for the “Winning Characteristics” Scholarship essay: “During my high school career, I have exhibited several of the “Winning Characteristics,” including Communication Skills, Leadership Skills and Organization Skills, through my involvement in Student Government, National Honor Society, and a part-time job at Macy’s Department Store.”
4. Write the body.
The body of your essay argues, explains or describes your topic. Each main idea that you wrote in your diagram or outline will become a separate section within the body of your essay.
Each body paragraph will have the same basic structure. Begin by writing one of your main ideas as the introductory sentence. Next, write each of your supporting ideas in sentence format, but leave three or four lines in between each point to come back and give detailed examples to back up your position. Fill in these spaces with relative information that will help link smaller ideas together.
5. Write the introduction.
Now that you have developed your thesis and the overall body of your essay, you must write an introduction. The introduction should attract the reader’s attention and show the focus of your essay.
Begin with an attention grabber. You can use shocking information, dialogue, a story, a quote, or a simple summary of your topic. Whichever angle you choose, make sure that it ties in with your thesis statement, which will be included as the last sentence of your introduction.
6. Write the conclusion.
The conclusion brings closure of the topic and sums up your overall ideas while providing a final perspective on your topic. Your conclusion should consist of three to five strong sentences. Simply review your main points and provide reinforcement of your thesis.
7. Add the finishing touches.
After writing your conclusion, you might think that you have completed your essay. Wrong. Before you consider this a finished work, you must pay attention to all the small details.
Check the order of your paragraphs. Your strongest points should be the first and last paragraphs within the body, with the others falling in the middle. Also, make sure that your paragraph order makes sense. If your essay is describing a process, such as how to make a great chocolate cake, make sure that your paragraphs fall in the correct order.
Review the instructions for your essay, if applicable. Many teachers and scholarship forms follow different formats, and you must double check instructions to ensure that your essay is in the desired format.
Finally, review what you have written. Reread your paper and check to see if it makes sense. Make sure that sentence flow is smooth and add phrases to help connect thoughts or ideas. Check your essay for grammar and spelling mistakes.
Congratulations! You have just written a great essay.
