Basic Concepts

Identifying Supporting Details

Building the Case with Details

Supporting details are the facts, examples, or reasons that back up the main idea. Think of them as the bricks building a strong house for the main idea.

Finding Details that Matter

  • Look for evidence: What facts or examples does the author use?
  • Check for explanations: How does the author clarify or expand on points?
  • Distinguish between key points and extra info: Not all details are equally important.

Why Supporting Details Matter

Understanding details helps you answer “how” and “why” questions, and proves you’ve truly understood the passage.

Examples

  • An article on healthy eating lists vitamins in vegetables as supporting details for why veggies are good for you.

  • A biography provides dates and events to reinforce the subject's accomplishments.

In a Nutshell

Supporting details are the evidence and examples that make the main idea believable.
