Definition

What is it?

A supporting detail is a piece of information, fact, example, or reason that helps explain or prove a main idea. It gives more information about the main point and makes it easier to understand.

Simple Example

Quick Example

Imagine your friend says, 'My mobile data finished quickly today!' This is the main idea. A supporting detail could be, 'I watched three cricket matches live on my phone.' This detail explains WHY the data finished quickly.

Worked Example

Step-by-Step

Let's find the supporting details for this main idea: 'It's important to drink enough water every day.'

--- Step 1: Read the main idea carefully. We know the topic is about drinking water.

--- Step 2: Think about why drinking water is important. What facts or reasons come to mind?

--- Step 3: Consider these sentences: 'Water helps your body stay healthy.' 'It keeps your skin glowing.' 'It helps you concentrate better in school.'

--- Step 4: Each of these sentences gives a reason or benefit related to drinking water. They explain why it's important.

--- Step 5: Therefore, 'Water helps your body stay healthy,' 'It keeps your skin glowing,' and 'It helps you concentrate better in school' are all supporting details for the main idea.

Why It Matters

Understanding supporting details helps you become a better reader and writer. Journalists use them to back up their news stories, and lawyers use them as evidence in court. This skill is key for anyone who wants to communicate clearly and convincingly, whether writing a school essay or presenting a project.

Common Mistakes

MISTAKE: Confusing a supporting detail with a new main idea. | CORRECTION: A supporting detail always relates directly back to and explains the main idea, it doesn't introduce a completely different topic.

MISTAKE: Including information that is interesting but doesn't actually support the main idea. | CORRECTION: Always ask, 'Does this information help explain or prove the main idea?' If not, it's not a supporting detail.

MISTAKE: Not having enough supporting details to make the main idea clear or convincing. | CORRECTION: Provide several relevant supporting details to fully explain and strengthen your main idea.

Real World Connection

In the Real World

When you read a news report about a new government scheme, the main idea might be the scheme's goal. The supporting details would be things like: who benefits, how much money is allocated, and where it will be implemented. Similarly, when you watch a cricket match analysis, the commentator gives the main idea (e.g., 'India won because of strong batting') and then provides supporting details like specific player scores, partnership runs, and boundary counts.
