The key idea
Build each paragraph around one main point, then explain it and give an example.
What is it for?
Learn how to develop one main idea in a clear, useful paragraph.
What you need to know
- Start with a sentence that states your main point.
- Explain the point so the reader understands your reason.
- Give an example that makes your explanation clear.
- Add a closing sentence when it helps finish the idea.
- Keep every sentence connected to the same main point.
- Start a new paragraph when you introduce a different main idea.
1. Give your paragraph one clear job
A paragraph develops one main point. The first sentence usually introduces it.
The other sentences explain, support, or finish that point. If a sentence discusses another subject, move it elsewhere.
- Ask yourself: What is this paragraph about?
- Write one sentence that answers this question.
- Check every other sentence against that main point.
Walking to work can improve your daily routine.
This sentence gives one clear main point.
My favourite meal is vegetable soup.
This introduces a different topic, so it needs another paragraph.
2. Explain your point and give an example
A main point often needs more information. Explain why it matters or how it works.
Then give an example from everyday life. A closing sentence can remind readers of the main point.
- Main point: introduce your idea.
- Explanation: give a reason or more information.
- Example: show what happens in a real or imagined situation.
- Closing sentence: finish the idea when needed.
Reading before bed can help you relax. It gives you time away from screens. For example, I read a short story instead of checking my phone. This habit helps me prepare for sleep.
The sentences move from the main point to an explanation, an example, and a closing sentence.
Cooking at home can save money. You can use ingredients you already have. For example, leftover vegetables can become a simple soup.
The example shows how the main point works.
3. Keep every sentence on topic
A paragraph should not contain unrelated information. Even an interesting sentence can distract readers.
Read each sentence and ask how it supports the main point. Remove it or move it if it does not belong.
- Keep details that explain or support your point.
- Remove details that belong to another subject.
- Save a new main idea for a new paragraph.
Cycling to work saves money. It also gives me daily exercise. My sister prefers blue shoes.
The last sentence does not support the point about cycling.
Cycling to work saves money. It also gives me daily exercise. As a result, I spend less on transport and exercise more often.
All three sentences support the same main point.
4. Put the sentences in a helpful order
Readers should understand your point without searching for its meaning. Put the main point first in most paragraphs.
Follow it with an explanation and an example. Finish with a closing sentence if one adds something useful. At B1, aim for four to seven sentences.
- A paragraph with one or two sentences may need more support.
- A paragraph with many sentences may contain two main ideas.
- Use a new paragraph when the focus changes.
- Read the whole paragraph to check its flow.
Learning a hobby can build confidence. You improve by practising regularly. For example, a beginner can learn three guitar chords in one week. Small steps make progress easier to notice.
The sentences follow a clear order and develop one idea.
My hobby is drawing. It helps me relax after work. My town has three supermarkets. I practise with a sketchbook every evening.
The supermarket sentence breaks the flow and should move elsewhere.
How to do it, step by step
- Choose one main point for the paragraph.
- Write a first sentence that introduces the point.
- Explain the point with a reason or more information.
- Add an example that supports your explanation.
- Write a closing sentence if it helps, then check every sentence.

Model text
Two Habits That Make Daily Life Easier
Paragraph 1: Main point
Preparing lunch at home is a smart daily habit because it saves money and gives you more control over your meals. You can choose fresh ingredients and make enough food for the next day. For example, I prepare rice, vegetables, and chicken on Sunday evening. I keep the meals in containers, so weekday lunches take only a few minutes to prepare. As a result, I spend less money at work and have more time during my lunch break.
The first sentence states the main point. The next sentences explain it and give a clear example. The final sentence shows the result.
Paragraph 2: Main point
A short evening walk can also make your day more enjoyable. Walking gives you time to move after sitting at a desk, and it can help you clear your mind. For instance, my fictional neighbour walks around the local park after dinner. She leaves her phone at home and notices the trees and birds along the path. After that, she returns home feeling more relaxed. This simple habit shows how a small change can turn a tiring evening into a relaxing one.
This paragraph develops a new main point. It includes reasons, a specific example, and a closing sentence. A new paragraph keeps the two habits separate.
Common mistakes
✗ I enjoy cycling. My favourite food is pasta. Cycling helps me stay active.
✓ I enjoy cycling. It helps me stay active. I also enjoy cycling to work.
The original middle sentence changes the subject and breaks the paragraph's unity.
✗ Reading is useful. Reading is useful. Reading is useful.
✓ Reading is useful because it helps me relax. For example, I read before bed.
Repeating the same point does not explain it or give an example.
✗ For example, exercise is useful.
✓ Exercise improves fitness. For example, walking each day helps me stay active.
The original sentence gives no main point before its example.
✗ For example, I prepare lunch. It saves money. Cooking at home is useful.
✓ Cooking at home is useful. It saves money. For example, I prepare lunch for work.
Starting with an example can make the main point harder to follow.
✗ Walking helps me relax. My bus arrives at eight. Walking also gives me exercise.
✓ Walking helps me relax. It also gives me exercise. I walk after work.
The bus detail does not support the main point about walking.
✗ My hobby is gardening. It helps me relax. It gives me fresh vegetables. I grow tomatoes. I water them each morning. My favourite film is a comedy. Gardening is rewarding.
✓ My hobby is gardening. It helps me relax and gives me fresh vegetables. I grow tomatoes and water them each morning. Gardening is rewarding.
The film sentence introduces another subject and should go in another paragraph.
Plan it, then check it
Plan
