English 52 – Topic & Main Idea

The Main Idea

Recognizing the main idea, or point, is
the most important key to good
comprehension.
To find the main idea, or point in a
reading selection, ask yourself:
“What is the main point the author is
trying to make?”

Main Idea = Umbrella

The Main Idea is a complete sentence that gives the
general idea of what a paragraph or reading is all
about.
The other material of the paragraph fits under the
general point.
When you think of the main idea, think of an umbrella
covering the passage of reading.

How do you recognize the Main Idea?

To recognize the main idea of a passage, you must
think as you read.
You cannot be a passive reader!
Here are three strategies that will help you find the
main idea:
1. Look for general versus specific ideas.
2. Use the topic to lead you to the main idea.
3. Use clue words to lead you to the main idea.

1. Look for General vs. Specific

In the list of words below, which three items are
specific ideas, and which item is the general idea?

Practice 4-5: 10 Steps Book, page 61-62

1. Look for general vs. specific details
Let’s read the paragraph below and figure out what the main
idea is.
Why would anyone want to leave San Diego, California? San Diego
has absolutely everything you will ever need to be happy! The
beaches are one of our major attractions. You can take a ride to
the Coronado Bay and sit on the sand and stare out at the city
skyline. Secondly, we have great theme parks, such as Sea World
and the San Diego Zoo. Next, we have a great downtown where
you will find wonderful museums and discover plenty of good
places to eat. Finally, the best part of San Diego is the people – we
are all proud to be San Diego natives.

The main idea is:
Sentence 2: San Diego has absolutely everything you will ever
need to be happy!

The specific details support the main
idea.
Why would anyone want to leave San Diego, California.
San Diego has absolutely everything you will ever need to
be happy! The beaches are one of our major attractions.
You can take a ride to the Coronado Bay and sit on the
sand and stare out at the city skyline. Secondly, we have
great theme parks, such as Sea World and the San Diego
Zoo. Next, we have a great downtown where you will find
wonderful museums and discover plenty of good places to
eat. Finally, the best part of San Diego is the people – we

2. Use the Topic to Lead You to the
Main Idea
The topic is the general subject of a reading selection.
Knowing the topic can help you find the writer’s main
point about that topic.
To find the topic of a selection, ask yourself: Who or
what is the selection about?
After you find the topic, ask yourself:
What main point is the author making about the topic?

2. Use the Topic to Lead You to the
Main Idea
In looking at the previous paragraph again, what do you
think the topic of the paragraph is?
Why would anyone want to leave San Diego, California. San
Diego has absolutely everything you will ever need to be happy!
The beaches are one of our major attractions. You can take a
ride to the Coronado Bay and sit on the sand and stare out at
the city skyline. Secondly, we have great theme parks, such as
Sea World and the San Diego Zoo. Next, we have a great
downtown where you will find wonderful museums and
discover plenty of good places to eat. Finally, the best part of
San Diego is the people – we are all proud to be San Diego
natives.

The topic will usually be repeated
several times within the paragraph.
Why would anyone want to leave San Diego, California.
San Diego has absolutely everything you will ever need to
be happy! The beaches are one of our major attractions.
You can take a ride to the Coronado Bay and sit on the

someone that you share a book with.

3. Find and Use Clue Words to Lead
You to the Main Idea
Sometimes an author announces the main idea by
using clue words or phrases.
One type of clue word is a list word.
A list word tells you that a list of items will follow.
There are many reasons why a person would want to live in
San Diego.

The above statement is informing the reader that a
list of reasons will follow indicating the positive
reasons for living in San Diego.

Another type of key word is the addition word.
It is generally used right before a supporting
detail.

supporting details and help you discover the main
idea.
