Main idea and detail

Separating the claim from the support.

Finding it

Ask what the whole passage is trying to persuade you of. A detail supports; the main idea is what the details are for. Summarising in one sentence tests whether you have it.

  • The topic is a noun phrase; the main idea is a full claim.
  • A main idea is rarely the most interesting sentence.

Summarising

Writing a one-line summary of each paragraph produces a map of the argument and exposes any paragraph that does not contribute.
