The main idea of a passage is its central point or argument that the author wants to convey, often supported by details throughout the text.

Finding the Main Idea

Authors typically state the main idea explicitly in the topic sentence (often first or last), but it can be implied through key details.

Look at the who (subject), what (actions), where (setting), when (time), and why (reasoning) to uncover it.

For example, in a passage about polite Canadians, the main idea might be "Canadians have a reputation for being polite and helpful," blending topic and controlling idea.

Step-by-Step Guide

  1. Identify the topic : What's the passage about in one word or phrase? (E.g., "infant crying.")
  1. Read fully and annotate : Underline repeated ideas, first/last sentences, and key evidence.
  1. Summarize in your words : Ask, "What's the author's big point?" Check if details support it across the whole text.
  1. Evaluate options : Pick the broadest idea backed by beginning, middle, and end—not too vague or specific.
