    Main ideas provide the structure for our efforts at communication. You may also know main ideas under their alias, “topic sentence.”

    • In reading we analyze main ideas to better understand what an author or speaker is trying to communicate.
    • In writing we use main ideas to organize paragraphs so that our audience can better understand what we are trying to communicate.

    Stated Main Idea

    Stated main ideas are exactly what they sound like – main ideas that are directly stated in a passage. You can literally underline or highlight a stated main idea in a text, and you should do this when you are reading a textbook for a class.

    Implied Main Idea: What are you trying to say?

    The word implied means “suggested but not directly expressed.” Use this definition to help you define “implied main idea.”

    What is an “implied main idea?”

    How is an implied main idea different from a stated main idea?

    How to find the Elusive Main idea

    How can you identify the main idea in a text or spoken communication? Whether you are looking at a stated main idea or an implied main idea, the following strategies can help.

    Strategy 1:

    Ask yourself:

    • What is the point of the piece?
    • What is the one thing the author/speaker wants me to know about this?

    Strategy 2:

    • If you are still struggling to locate the main idea, back up and identify the topic. The topic is a word or phrase that the paragraph is about.
    • Then ask yourself “what about” the topic? This is likely the main idea.
    • It never hurts to discuss the piece with another person. Sometimes this helps you to clarify your understanding.

    Strategy 3 – for implied main ideas:

    • Read the passage for which you are seeking a main idea. Look for words or ideas that are repeated frequently.
    • Then use Strategy 2 to derive your own version of a main idea statement.

    Main Ideas and Details are in a Relationship

    Main ideas and supporting details have a pretty simple relationship. The main idea is the center of attention, and the supporting details function to support the main idea. If these were two people, this would be a pretty unfair relationship, but in writing or speaking, it is entirely acceptable. After all, only one idea can be the ‘focus.’

    Whether you are reading, treasure-hunting to find main ideas and supporting details in your textbook, or you are writing an essay, a graphic organizer can be a helpful tool. There are all kinds of graphic organizers and metaphors for working with main ideas and supporting details, but sometimes it’s more efficient to use a simple diagram. Review the diagrams and graphic organizers for main ideas by doing a Google search.

    Look Ahead

    Check your syllabus. What assignments are coming up to which you will apply your understanding of main ideas and supporting details? When will this be due?
