Guidelines for starting a new paragraph

Starting a new paragraph is a critical aspect of writing that helps organize ideas and improve readability. It always happens according to the topic and structure of your writing.

Many writers follow these guidelines and use paragraph generator tool while they face writer block. This generator helps them write effectively. It is a better option than writing paragraphs by hand and putting a lot of effort and time into writing them.

  • When you start discussing a different idea or point, each paragraph should focus on a single topic to maintain clarity.
  • When the tone or mood of the writing changes, start a new paragraph to reflect this shift. This helps convey the change to the reader more effectively.
  • Avoid overly long paragraphs. Break them into smaller, more manageable chunks to maintain reader interest and avoid complexity in your writing
  • In narrative writing, different characters speak. This keeps the dialogue clear and easy to follow.
  • When the narrative or argument shifts in time or place, it's a good time to start a new paragraph to indicate the change to the reader.
  • Use a new paragraph to summarize points or to conclude a section before transitioning to a new topic. This provides a clear endpoint to your current discussion.

3 main parts for developing a good paragraph

A strong paragraph should consist of three main parts: the topic sentence, supporting information, and the conclusion. Each of these elements plays a crucial role in creating a well-structured, coherent, and effective paragraph. Let's discuss each part in detail with examples.

1. Topic sentence

The topic sentence is the foundation of a good paragraph. It introduces the main idea or the central point that the paragraph will discuss. A strong introductory paragraph should be clear, concise, and specific. It sets the tone for the rest of the paragraph and gives readers an idea of what to expect.


  • Regular exercise offers numerous health benefits, both physical and mental.

Explanation: This topic sentence clearly states the main idea of the paragraph - the benefits of regular exercise. It also hints at the scope of the discussion by mentioning both physical and mental benefits. The reader immediately understands that the following sentences explain the benefits of health.

Here is another example:

  • Many students struggle with math.

Explanation: This sentence introduces a topic without going into specific details. It's clear and straightforward, making it easy for readers to understand the main idea.

Have a look at this example:

  • Many parents do not prefer to take their children out to dinner with them because they disturb them and the entire restaurant with their noise.

Explanation: Even though it's clear what the sentence is about, it has some extra details that aren't needed. We don't really need to mention "the entire restaurant" because it's obvious that noise would disturb everyone there. Also, saying "do not prefer" is just a fancy way of saying "don't like."

A simple sentence might be like this:

  • Parents often avoid taking their children out to eat because they can be noisy and disturb others.

Activity 1

Make each of the following topics smaller so that you can discuss them in a single paragraph. Then, write a sentence that expresses the main idea of your paragraph. This sentence is known as a topic sentence. It should be clear and show what the whole paragraph will be about.

  • Food
  • Music
  • Friends
  • School

Write your four topic sentences in a notebook. Make sure each sentence:

  • Is about your smaller topic
  • Tells the main idea
  • Is clear and easy to understand

2. Supporting sentence 

 After the topic sentence, the paragraph should provide supporting details that expand on, explain, or prove the main idea. These details can include facts, statistics, examples, or expert opinions. Good supporting details are relevant, specific, and logically organized.

Example (continuing from the previous topic sentence): 

  • Physically, exercise helps maintain a healthy weight, strengthens muscles and bones, and reduces the risk of chronic diseases like heart disease and diabetes. A study by the American Heart Association found that people who engage in 150 minutes of aerobic activity per week have a 14% lower risk of coronary heart disease. 

Explanation: The supporting details in this example directly relate to the topic sentence. They provide specific benefits such as weight management, stronger muscles and bones, which are supported by credible sources such as the American Heart Association. 

Activity 2

Consider the four topic sentences you wrote for activity 1. Write your three supporting sentences below your topic sentence. For each supporting sentence, say what kind it is. It could be:

    • Fact: Something that is true
  • Reason: Why something happens or is true
  • Statistic: A number that shows information
  • Quote: Words someone said
  • Use this format:

Topic Sentence: _____________________

Supporting sentence # 1_________________(type)

Supporting sentence # 2_________________(type)

Supporting sentence # 3_________________(type)

3. Conclusion paragraph

Conclusion is the crux of the whole information you have discussed above in your whole writing. It helps create a sense of closure and can also serve as a transition to the next paragraph. This part concludes the sentence and wraps up the paragraph by describing:

  • The main idea
  • Summarizing the key points
  • Providing a final thought that supports the paragraph's purpose


  • With all of these benefits, it is easy to see that exercising frequently is a great way to stay healthy and feel good.


This concluding sentence summarizes the main idea of exercise's benefits. It also adds a call to action "exercising frequently is a great way to stay healthy" and a powerful phrase that shows the importance of the topic. It provides a great conclusion to the paragraph without introducing new information.

Activity 3

Look at your work from activity 2. You have a topic sentence and three supporting sentences. Now, write two ending sentences for your paragraph:

  • First ending: Sum up your main idea using different words.
  • Second ending: Do one of these:
    • Make a guess about what might happen next.
    • Give advice on what people should do.
    • Say what you learned or think because of your topic.

Now, write both endings in your notebook and choose which ending you prefer. Then, explain why you prefer it more. Finally, put it all together:

  • Start with your topic sentence.
  • Add your three supporting sentences.
  • End with the concluding sentence you like best.
