In composition , unity is the quality of oneness in a paragraph or essay that results when all the words and sentences contribute to a single effect or main idea; also called wholeness .

For the past two centuries, composition handbooks have insisted that unity is an essential characteristic of an effective text . Professor Andy Crockett points out that the " five-paragraph theme and  current-traditional rhetoric 's emphasis on method reflect further the expediency and utility of unity." However, Crockett also notes that "for rhetoricians , the achievement of unity has never been taken for granted" (Encyclopedia of Rhetoric and Composition, 1996.)

Pronunciation

From the Latin, "one."

Observations

  • "Most pieces of effective writing are unified around one main point. That is, all the subpoints and  supporting details are relevant to that point. Generally, after you have read an essay, you can sum up the writer's main point in a sentence, even if the author has not stated it explicitly. We call this summary statement a thesis ." (X. J. Kennedy, Dorothy M. Kennedy, and Marcia F. Muth, The Bedford Guide for College Writers, 8th ed. Bedford/St. Martin's, 2008)
  • Unity and Coherence "A good check on unity is to ask yourself if everything in your paragraph or essay is subordinate to and derived from the controlling idea. Make sure that your controlling idea—the topic sentence or thesis—indicates the subject and the focus on that subject..."​ (Lee Brandon and Kelly Brandon, Paragraphs and Essays With Integrated Readings, 12th ed. Wadsworth, 2012)

Rules of Thumb for Writing Unified Paragraphs

  • Be sure your paragraphs focus on one idea and state that idea in a topic sentence.
  • Place your topic sentence effectively within your paragraph. Let the purpose of your paragraph and the nature of your evidence guide you.
  • Let your paragraph's evidence —the selected details , the examples — illustrate or clarify the idea expressed in your topic sentence.
  • Make sure you explain the relationship between your evidence and your idea so that it is clear to readers.
  • Think about unity among paragraphs when writing essays. Be sure your paragraphs are related, that they fit together and clarify your essay's idea.​ (R. DiYanni, Scribner Handbook for Writers. Allyn & Bacon, 2001)

A Note on Topic Sentences

  • "Paragraphs may not have a topic sentence, but they must have unity and purpose . All the ideas in a paragraph should relate to a clear point readers will easily understand." (Mark Connelly, Get Writing: Paragraphs and Essays. Thomson Wadsworth, 2009)

Counterviews on Unity

  • " Unity is the shallowest, the cheapest deception of all composition ... Every piece of writing, it matters not what it is, has unity. Inexpert or bad writing most terribly so. But ability in an essay is a multiplicity, infinite fracture, the intercrossing of opposed forces establishing any number of opposed centres of stillness." (William Carlos Williams, "An Essay on Virginia," 1925)

Paragraph Unity, Coherence, and Development

In each paragraph of an essay, one particular idea or topic is developed and explained. In order to successfully do so, however, it is essential that the paragraph be written in a unified and coherent manner. 

A unified paragraph must follow the idea mentioned in the topic sentence and must not deviate from it. For a further explanation on topic sentences, see the Write Right on Topic Sentences .

A coherent paragraph has sentences that all logically follow each other; they are not isolated thoughts. Coherence can be achieved in several ways. First, using transitions helps connect ideas from one sentence to the next. For more on transitions, see the Write Right on Transitions . Second, ordering thoughts in numerical sequence helps to direct the reader from one point to the next. Third, structuring each paragraph according to one of the following patterns helps to organize sentences: general to particular; particular to general; whole to parts; question to answer; or effect to cause. 

Remember that a paragraph should have enough sentences so that the main idea of the topic sentence is completely developed. Generalizations should be supported with examples or illustrations. Also, details and descriptions help the reader to understand what you mean. Don't ever assume that the reader can read your mind: be specific enough to develop your ideas thoroughly, but avoid repetition

An effective paragraph might look like this:

It is commonly recognized that dogs have an extreme antagonism toward cats. This enmity between these two species can be traced back to the time of the early Egyptian dynasties. Archaeologists in recent years have discovered Egyptian texts in which there are detailed accounts of canines brutally mauling felines. Today this type of cruelty between these two domestic pets can be witnessed in regions as close as your own neighborhood. For example, when dogs are walked by their masters (and they happen to catch sight of a stray cat), they will pull with all their strength on their leash until the master is forced to yield; the typical result is that a feline is chased up a tree. The hatred between dogs and cats has lasted for many centuries, so it is unlikely that this conflict will ever end.

This paragraph is effective for the following reasons:

  • The paragraph shows unity. All the sentences effectively relate back to the topic sentence at the beginning of the paragraph. 
  • The paragraph shows coherence. There is a flow of thoughts and ideas among the sentences in this paragraph. There are good transitions employed in the paragraph. The writer also presents her sub-topics in an orderly fashion that the reader can follow easily.
  • The paragraph is developed. The writer gives herself enough space to develop the topic. She gives us at least two reasons to accept her argument and incorporates some examples in order to give those reasons more validity.

11 Unity & Coherence

Preserving unity.

Academic essays need unity, which means that all of the ideas in an essay need to relate to the thesis, and all of the ideas in a paragraph need to relate to the paragraph’s topic. It can be easy to get “off track” and start writing about an idea that is somewhat related to your main idea, but does not directly connect to your main point.

Train Tracks

All of the sentences in a paragraph should stay “on track;” that is, they should connect to the topic. One way to preserve unity in a paragraph is to start with a topic sentence that shows the main idea of the paragraph. Then, make sure each sentence in the paragraph relates to that main idea.

If you find a sentence that goes off track, perhaps you need to start a separate paragraph to write more about that different idea. Each paragraph should generally have only one main idea.

As you pre-write and draft an essay, try to pause occasionally. Go back to the assignment prompt and re-read it to make sure you are staying on topic. Use the prompt to guide your essay; make sure you are addressing all of the questions. Do not just re-state the words in the prompt. Instead, respond to the questions with your own ideas, in your own words, and make sure everything connects to the prompt and your thesis.

Activity A ~ Finding Breaks in Unity

Consider the following paragraphs. Is there a topic sentence? If so, do all of the other sentences relate to the topic sentence? Can you find any sentences that don’t relate?

     The planned community of Columbia, Maryland, was designed as a city open to all, regardless of race, level of income, or religion. When Columbia began in 1967, many cities in the U.S. did not allow people of certain races to rent or buy homes. Its developer, James W. Rouse, wanted to build a new city that had fair and open housing options for everyone. HCC has a building named for James W. Rouse. Today, the city’s nearly 100,000 remain diverse, as shown by recent census data. *****
    College can be expensive and difficult. Critical thinking is a very important skill for college students to develop so that they can be successful in their careers. Employers look for graduates who can understand information, analyze data, and solve problems. They also want employees who can think creatively and communicate their ideas clearly. College students need to practice these skills in all of their classes so that they can demonstrate their abilities to potential employers. ***** Bananas are one of Americans’ favorite types of fruit. The Cavendish variety, grown in Central and South America, is the most commonly sold here in the U.S. Recent problems with a fungus called Panama disease (or TR4), however, have led to a shortage of Cavendish bananas. Similar problems occurred a few years ago in parts of Asia and the Middle East. Because the fungus kills the crop and contaminates the soil, scientists are concerned that the popular Cavendish banana could be completely eradicated. Bananas contain many nutrients, including potassium and Vitamin B6. *****

Whether you choose to include a topic sentence or not, all of the sentences in your paragraph need to relate to the one main idea of the paragraph.

Another way to think about unity in a paragraph is to imagine your family tree. Draw a quick sketch of your family tree in your notebook. If you were writing an essay about your family, you might write a paragraph about close family members first. Next, you might branch out into another paragraph to write about more distant relatives. You might even include a paragraph about very close family friends, or pets. Each paragraph would have just one main idea (immediate family, more distant relatives, close family friends), and every sentence in each paragraph would relate to that main idea.

Activity B ~ Preserving Unity in Your Own Writing

Examine a composition that you have written for this class. Do all of your paragraphs have unity? Can you find any sentences that don’t relate to the topic of each paragraph? Exchange papers with a partner to peer review.

Ensuring Coherence

There are several ways to create connections between ideas in your essay. Here are some suggestions:

1. Repeat key words and phrases. This can be a powerful way to make a point. Consider this excerpt from Rev. Martin Luther King’s famous “I Have a Dream” speech at the 1963 March on Washington for Jobs and Freedom, in which he uses parallel structure :

I say to you today, my friends, so even though we face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream. I have a dream that one day this nation will rise up and live out the true meaning of its creed: “We hold these truths to be self-evident, that all men are created equal.” I have a dream that one day on the red hills of Georgia, the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood. I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today.

2. Use synonyms , as in this example, where King uses both repetition (“Let freedom ring”) and synonyms (for “mountains”):

And if America is to be a great nation, this must become true. So let freedom ring from the prodigious hilltops of New Hampshire. Let freedom ring from the mighty mountains of New York. Let freedom ring from the heightening Alleghenies of Pennsylvania. Let freedom ring from the snow-capped Rockies of Colorado. Let freedom ring from the curvaceous slopes of California. But not only that: Let freedom ring from Stone Mountain of Georgia. Let freedom ring from Lookout Mountain of Tennessee. Let freedom ring from every hill and molehill of Mississippi. From every mountainside, let freedom ring.

3. Use pronouns to refer to antecedents , as King does here; this can be more elegant than just repeating the key words and phrases:

I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.

4. Use demonstratives ( this, that, these, those ) as adjectives or pronouns, as King does here:

I say to you today, my friends, so even though we face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream. I have a dream that one day this nation will rise up and live out the true meaning of its creed: “We hold these truths to be self-evident, that all men are created equal.”…. This is our hope. This is the faith that I go back to the South with. With this faith we will be able to hew out of the mountain of despair a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood.  

Questions to Ponder

Pause for a moment here to think about the examples above. Think about audience, purpose, and context of an academic essay. Would you use the techniques for coherence in the same way that Dr. King did in his speech, or would you use the techniques in a different way? Discuss with a small group.

5. Use transitions. Transition words and phrases will help you to make sure your essay has coherence. Also called signal words/phrases or signposts, these help to guide your readers.

Transitions connect your related ideas; they can also show your reader that you are starting a new topic, giving an example, adding information, explaining causes and effects, and so on. Using the correct transition word or phrase in a sentence can make your writing much clearer. Try the activity below to think of possible transitions.

Activity C ~ Transition Words & Phrases

With your partner, brainstorm a list of transition words and phrases for each of the categories below.

Can you think of other transition words and phrases? What other categories do they belong to?

After you have completed these activities with your partner, consult  Transition Words & Phrases ~ Useful Lists for more on compare/contrast, addition, cause/effect, and other transitions to try.

Activity D ~ Ensuring Coherence in Your Own Writing

Examine a composition that you have written for this class for coherence. Find and mark examples of places where you used repetition, synonyms, pronouns or demonstratives to build connections between ideas.

Underline your transition words and phrases. Did you use the strongest signal words? Can you find examples where you need to add a transition? Or, did you use too many transitions? Exchange papers with a partner to peer review.

Consult our chapter on Transitions for more inspiration on achieving coherence and cohesion in your writing. Challenge yourself to use some new transitions in your next composition.
