Writing a strong paragraph requires more than just putting sentences together. The key lies in understanding unity, a principle that ensures every sentence in a paragraph works toward the same goal. This concept is essential for anyone learning to write effectively in English, and mastering it transforms paragraphs from scattered ideas into powerful, focused messages.
What does unity mean when writing a paragraph?
Unity means that a paragraph discusses only one main idea [0:42]. That main idea is stated in the topic sentence, and every supporting sentence must directly explain or prove it. If a sentence doesn't connect back to the topic sentence, it breaks unity and weakens the paragraph.
Consider this example [1:02]: the topic sentence is "My mom is extremely generous." Here, "my mom" is the topic, and "extremely generous" is the controlling idea that limits what will be discussed. Every supporting sentence must prove generosity:
- She often lets people in need stay in her home.
- She has even hosted homeless people temporarily.
- She sends money to her family in Chile every month to help with their bills.
- She always brings flowers or food to friends when they are sick.
Each sentence provides examples and facts that prove generosity. The concluding sentence then paraphrases the main idea: "My mother is one of the most generous people I know" [1:52].
How does the gold paragraph demonstrate unity?
The paragraph about gold, practiced in a previous module, serves as another clear example [2:06]. Its topic sentence states: "Gold, a precious metal, is prized for two important characteristics." This means the supporting sentences must explain exactly those two characteristics: beauty and usefulness.
The concluding sentence reinforces unity by paraphrasing: "In conclusion, gold is treasured not only for its beauty, but also for its utility" [2:31]. Notice how the author circles back to the controlling idea without introducing new information.
How can you identify sentences that support unity?
Practicing recognition is just as important as writing. Given the topic sentence "It's easy to get a sports injury" [2:47], only one option truly supports it:
- "Many people make the mistake of joining a gym, and then they never go to it." — talks about gym habits, not injuries.
- "Runners often have problems with their ankles and knees." — directly relates to sports injuries.
- "Lots of people love playing sports." — too general, doesn't prove the main idea.
The correct answer connects ankle and knee problems to the concept of sports injury [3:18].
What about the architecture example?
With the topic sentence "My city is famous for its architecture" [3:30], two sentences maintain unity:
- "We have antique blue tile buildings at downtown."
- "It has lavish tree-lined boulevards with beautiful buildings and monuments."
Sentences about a bar on a mountain or restaurant portions near the airport don't explain architecture, so they break unity [4:06].
How can you practice writing unified paragraphs?
Three topic sentences are proposed for practice [4:20]:
- "Computers are useful in many ways."
- "There are some characteristics that I always look for in a good hotel."
- "There are many ways to show respect to other people."
The task is to choose one and write as many supporting sentences as possible, ensuring each one directly explains or proves the main idea. Before writing each sentence, ask yourself: does this sentence connect to the topic sentence? If the answer is no, it doesn't belong in the paragraph.
Remember the quote shared at the beginning: "What is written without effort is read without pleasure" [0:22]. Taking time to check unity in every paragraph is the effort that makes writing worth reading. Share your paragraph and see how well your supporting sentences hold together.
