Concept Explanation
The topic is the general subject; the main idea is what the writer wants you to understand about that subject. In a clear paragraph, the main idea often appears in a topic sentence, but it can also be developed through repeated points, examples, and the conclusion.
Ask: What is this section mostly saying? If you remove examples, names, and numbers, what claim remains? A useful one-sentence summary keeps the writer's meaning and does not add your opinion.
- Topic: what the text is about.
- Main idea: the central point about that topic.
- Supporting details: facts, examples, reasons, or explanations.
- Summary: the main idea in your own concise words.
