The main idea is the point or message - what an author presents and what a reader takes from a text. 

Searching for that main idea is a very important activity in understanding a text. It is usually found in the opening paragraph when the author is  setting up the topic  and  expressing the thesis.  

However, the location can vary according to the type of reading. For example, a research article's main idea is toward the end, whereas a persuasive essay's main idea is conveyed at the beginning.

Pre-read to Determine the Overall Topic

Examine the title and then skim the text to determine who or what the reading is about. If you see the same word repeated you know that it is likely the topic or at least an important element of the topic. The topic should be a noun or a noun phrase such as "online education." The topic itself does not convey any meeting us you must read on to determine the main idea.

Ask yourself questions about the text as you read in-depth. Pay close attention to the introduction, the first sentence of body paragraphs, and the conclusion. In these places, the author typically states and supports the main idea. 

Questions to Ask Yourself While Reading : 

• What elements make up this topic?
• What is the author saying about this topic?
• What does the author want me to know or believe about this topic?

Reflect on what you have read. If the main idea is not immediately apparent to you review the introduction and conclusion. The  main idea should be a complete thought  such as "because of its flexibility, comfort, and lower-cost online education is increasing in popularity for younger generations."

Questions to Ask Yourself While Reflecting:

• What is the message I take away from this reading?
• What point does the information add up to?
• What idea does the author reinforce in the conclusion?
• What is the final impression I have about this topic?

Finding the Main Idea

Once you believe you have found the main idea, check that each body paragraph relates to that main idea. The body paragraph should include  supporting ideas  that reinforce and provide greater detail about the main idea. 

Some students find it beneficial to sketch the main idea and supporting ideas in their notes as a concept map.

How to Find the Main Idea

ThoughtCo / Mary McLain 

• B.A., English, University of Michigan

Questions about the "main idea" of a passage are popular on reading comprehension tests, but sometimes, those questions are pretty difficult to answer, especially for students who are not completely sure they understand what the main idea really is.  Finding the main idea of a paragraph or longer passage of text is one of the most important reading skills to master, along with concepts like making an inference , finding the author's purpose , or understanding vocabulary words in context.

Here are a few techniques to help understand what, exactly, is a "main idea" and how to identify it accurately in a passage.

How to Define the Main Idea

The main idea of a paragraph is the primary point or concept that the author wants to communicate to the readers about the topic. Hence, in a paragraph, when the main idea is stated directly, it is expressed in what is called the topic sentence . It gives the overarching idea of what the paragraph is about and is supported by the details in subsequent sentences in the paragraph. In a multi-paragraph article, the main idea is expressed in the thesis statement, which is then supported by individual smaller points.

Think of the main idea as a brief but all-encompassing summary. It covers everything the paragraph talks about in a general way, but does not include the specifics. Those details will come in later sentences or paragraphs and add nuance and context; the main idea will need those details to support its argument.

For example, imagine a paper discussing the causes of World War I . One paragraph might be dedicated to the role that imperialism played in the conflict. The main idea of this paragraph might be something like: "Constant competition for massive empires led to increasing tensions in Europe that eventually erupted into World War I." The rest of the paragraph might explore what those specific tensions were, who was involved, and why the countries were seeking empires, but the main idea just introduces the overarching argument of the section.

When an author does not state the main idea directly, it should still be implied , and is called an implied main idea. This requires that the reader look closely at the content—at specific words, sentences, images that are used and repeated—to deduce what the author is communicating.

Finding the main idea is critical to understanding what you are reading. It helps the details make sense and have relevance, and provides a framework for remembering the content. Try these specific tips to pinpoint the main idea of a passage.

1) Identify the Topic

Read the passage through completely, then try to identify the topic. Who or what is the paragraph about? This part is just figuring out a topic like "cause of World War I" or "new hearing devices;" don't worry yet about deciding what argument the passage is making about this topic.

2) Summarize the Passage

After reading the passage thoroughly, summarize it in your own words in one sentence . Pretend you have just ten to twelve words to tell someone what the passage is about—what would you say?

3) Look at the First and Last Sentences of the Passage

Authors often put the main idea in or near either the first or last sentence of the paragraph or article, so isolate those sentences to see if they make sense as the overarching theme of the passage. Be careful: sometimes the author will use words like but , however ,  in contrast , nevertheless , etc. that indicate that the second sentence is actually the main idea. If you see one of these words that negate or qualify the first sentence, that is a clue that the second sentence is the main idea.

4) Look for Repetition of Ideas

If you read through a paragraph and you have no idea how to summarize it because there is so much information, start looking for repeated words, phrases, or related ideas. Read this example paragraph :

A new hearing device uses a magnet to hold the detachable sound-processing portion in place. Like other aids, it converts sound into vibrations, but it is unique in that it can transmit the vibrations directly to the magnet and then to the inner ear. This produces a clearer sound. The new device will not help all hearing-impaired people—only those with a hearing loss caused by infection or some other problem in the middle ear. It will probably help no more than 20 percent of all people with hearing problems. Those people who have persistent ear infections, however, should find relief and restored hearing with the new device.

What does this paragraph consistently talk about? A new hearing device. What is it trying to convey? A new hearing device is now available for some, but not all, hearing-impaired people. That's the main idea!

Avoid Main Idea Mistakes

Choosing a main idea from a set of answer choices is different than composing a main idea on your own. Writers of multiple choice tests are often tricky and will give you distractor questions that sound much like the real answer. By reading the passage thoroughly, using your skills, and identifying the main idea on your own, though, you can avoid making these 3 common mistakes : selecting an answer that is too narrow in scope; selecting an answer that is too broad; or selecting an answer that is complex but contrary to the main idea.

Identifying the main idea of the story: A Guide for Students and Teachers

READING FOR MEANING: IDENTIFYING THE MAIN IDEA OF THE STORY

We have all been there, though it can often feel as futile as the search for that proverbial needle in a haystack…

Finding the main idea of a piece of writing can be challenging, but it is an essential reading comprehension skill for our students to develop. Students that become skilled in this art will benefit from it far beyond the perimeters of the school gates. From the small print of an insurance document to writing a book review, the ability to filter a text and identify its central idea is as much a crucial life skill as an essential literacy-based learning objective. Though it isn’t always easy, luckily, there is much we can do to help our students hone their abilities in this area.

WHAT IS ‘THE MAIN IDEA’? DEFINITION

Whether we are talking about the main idea of a paragraph, a poem, a chapter, or a longer text, finding the main idea requires the reader to identify the topic of a piece of writing and then uncover what the writer wants us to know about that topic.

As is so often the case, it is best to start small. When working with students on how to identify the main idea, begin by having students locate the main idea in a sentence before building up to locating it in a longer paragraph. As students gradually build their confidence in identifying the main idea in paragraphs, they will soon be ready to move on to longer texts in the form of chapters and eventually full-length books.

TEACHING ACTIVITIES FOR ANY TEXT – GREAT FOR GUIDED READING

This massive collection of ☀️ READING ACTIVITIES☀️ covers all essential reading skills for elementary/primary students. NO PREP REQUIRED! works with all text and media types. Thousands of teachers have adopted this as a GO-TO RESOURCE for independent and group tasks.

A WORD ON PARAGRAPHS

The main idea of a sentence is usually fairly straightforward to identify. Often it is as simple as identifying the subject of the sentence. Whole chapters or books, on the other hand, can seldom be easily reduced to expression in the form of a single, main idea. For these reasons, the paragraph offers the student the most suitable format in which to practice their main idea identification skills.

Usually, if the writer knows what they are doing, we can identify a single main idea in every paragraph. We can think of this as the key point that is usually expressed as a topic sentence. It is often found in the paragraph’s first sentence, with subsequent sentences providing the supporting details. It can, however, occur in the middle, at the end, or even be split across the paragraph. It may not even be there at all – at least not explicitly.

Writers are a creative bunch, and so students will require more sophisticated means to accurately identify the main idea in all cases and that is exactly what this article will help you help your students to do.

HOW IS A MAIN IDEA EXPRESSED?

It can appear to be a reasonably clear-cut task to define the main idea, so why is it often so problematic for students to identify it? Well, the truth is that it needn’t be so. Often the central concept is expressed directly in the text and is as easy to identify as your own face in the mirror.

However, the main idea will not always be expressed so explicitly, and students must learn to identify it, whether it is expressed directly or merely implied, if they are to fully comprehend what they are reading.

  THE STATEMENT OF THE MAIN IDEA

Attention is the key to pulling the main idea from a text, whatever the genre. Students need to identify the most relevant information from the work and use it to develop a statement expressing what they perceive as the main idea.

We can refer to this as The Statement of the Main Idea . This statement should be a lean sentence or two. The process of composing this statement starts with asking questions about the text. Not all questions will apply to every text, but they will provide a good starting point for extracting the main idea from any piece of writing.

●     Who – Can the student identify the person or people the text is about?

●     What – Can the student identify the topic or underlying theme of the text?

●     When – Can the student identify a reference to a specific time or period?

●     Where – Can the student identify a specific place or a setting ?

●     Why – Can the student identify a reason or explanation for what happens in the text?

●     How – Can the student identify a method or theory in the text?

These questions, and variations of these questions, can help students draw out what the text is about. The two most important questions of those above are who and what . These will sufficiently elicit the information required to identify the main idea in most circumstances. But, the actual litmus test of whether the student can absorb the text’s central idea is whether or not they can summarize what they have read in their own words.

The Litmus Test: Summarizing and Paraphrasing

We know through our experience in the classroom that learning through teaching is a highly effective instructional strategy. It also offers teachers opportunities to observe and assess their students’ grasp of the concepts they have been working on. Similarly, when we ask our students to summarize or paraphrase the main idea of an extract, we are creating an opportunity to observe their comprehension of what they have read and their ability to identify the main idea therein.

You can also encourage students to regularly practice these skills by challenging them to paraphrase and summarize things you have said or read to them in class, even during lessons entirely unrelated to literacy. Encourage them to be concise and to the point; you may even wish to set a word limit of 10 or 15 words within which they must express the main idea. Keep it lean!

STRATEGIES FOR SUCCESS IN IDENTIFYING THE MAIN IDEA

Get The Gist

In this method, give each student a copy of a nonfiction paragraph. If you wish, you can differentiate for students’ different abilities by choosing extracts of varying complexities. Regardless of the level of difficulty, the approach will remain the same. Have students:

1. Ask themselves who or what the paragraph is about.

2. Ask themselves what is the most essential information about the who or what.

3. Restate the main idea in 10 words or less.

You can model this strategy for your students by first walking them through the process. Project the text onto the whiteboard for shared reading and, with focused support and prompting, have them answer the initial questions.

Part 3 of the process above can be undertaken as a piece of shared writing which will model the correct approach before students begin to do it independently. Later, when students have written independent statements of the main idea, they can compare their responses and offer each other feedback. After feedback sessions, they can be given a further opportunity to redraft and modify their statements for accuracy and brevity.

Through these processes, students will improve their ability to identify and express the main idea clearly and concisely.

Get the Gist – Longer Texts

As we mentioned earlier, it isn’t always easy to reduce a longer extract, such as a chapter, down to a single central idea – much less a whole book! There will be times, however, when students will be asked to do just that. They will need a systematic approach to help them in such circumstances. The following process provides for a practical approach:

1. Look at the title – Often, the title provides a good indication of the topic of the text or at least helps to orientate the reader in the direction of the main idea.

2. Look at the extract’s first and last sentences/paragraphs – Often, the main idea will be introduced and summarized respectively in these parts of the text.

3. Look for repeated words and phrases in the extract -The frequency with which they occur will be a strong indicator of their relative importance and will point students toward that elusive main idea.

4. Instruct students to ask themselves, “ What does the writer want me to know? ” – Answering this question successfully will require them to uncover the text’s main idea.

As the students work through the above steps, they can highlight, underline, or circle the keywords and phrases and then use these to help them form their main idea statement.

HOW TO LOCATE THE MAIN IDEA WHEN IT IS IMPLIED

Inferring the main idea requires students to look for patterns in the details as they read. When the main idea is explicit, the student must first identify the topic of the writing before determining what it is the writer wants the reader to know about it. If the main idea is not stated explicitly in a sentence or paragraph, then it is implied, and students must consciously work to uncover it by analysing the details to infer the main idea. Conscious practice of this strategy will soon see it become second nature, and the student will quickly become skilled in identifying the main idea even when it is not stated explicitly.

To efficiently identify the main idea in a piece of writing, students should first determine the text’s topic. Then, they will need to work out what it is the writer wants us to understand about that topic. This is the essence of how to identify the main idea.

Students should understand that the main idea may not always be explicit, and they may need to work hard to uncover precisely what the text implies. Regardless of whether the main idea is explicit or implicit, every paragraph will have the main idea. Students should understand that it can be located at the beginning, in the middle, at the end, or even be split up throughout the paragraph.

With perseverance and hard-earned experience, students can use various methods and, at times, a fusion of these methods to uncover the main idea with speed and accuracy. Soon they will be able to apply these methods to a broad range of texts over a wide range of lengths and complexities.

Understanding & Interacting with a Text

Finding the main idea in a piece of writing is a basic reading skill. No matter what type of expository text you read, the primary comprehension goal is to identify the main idea: the most important point that the writer wants to communicate.  Main ideas are often stated toward the start of a text, usually in an introductory paragraph. They are often repeated in fuller form toward the end of a text, usually in a concluding paragraph. Main ideas may be reinforced through headings, subheadings, and other forms of emphasis. However, main ideas may also be implied and not stated directly in the text.  Sometimes you need to infer the main idea based on the details, facts, and explanations in the text.

Some texts make the task of identifying the main idea relatively easy. Articles in scholarly journals often include an abstract, which is a condensed version of the information in the article, a version which focuses on main ideas. Textbooks, articles in general interest magazines, and online articles in blogs or on websites may include headings and subheadings which make it easier to identify core concepts. All types of texts may include graphic features such as sidebars, diagrams, and charts, which help readers understand complex information and distinguish between essential and inessential points. When reading a text with these features, use them to help identify the main idea.

For texts without graphic features, headings, or abstracts, and/or for texts with implied main ideas, use the following process to identify the main idea:

• Read the text.
• Ask yourself: What is the text about? – What is the topic?
• Ask yourself: What is the author saying about the topic?
• Identify repeated concepts and language; writers often use repetition to emphasize a main idea.
• Summarize the article after you read–put what you think the main idea is into your own words.  See if you can find any statements in the article that are similar to your summary.  If so, it’s likely that you’ve found the main idea.  If the main idea in the text is not stated but implied, then ask if your summary encapsulates the one thing you think the writer wants you to understand about the topic.

For a discussion of finding the main idea which includes examples, link to Finding the Main Idea from Monterey Peninsula College’s Writing Center.

The following two videos also provide very clear, useful discussions of finding the main idea in a text.

Read the article, “ Wikipedia Is Good for You!? ”  Then choose the statement that you think best offers the main idea.  In the answer, you’ll also find one reader’s discussion of her thought process finding the main idea.

• Wikipedia is a good source in certain cases.
• Wikipedia, although itself not always a valid source, is useful as a starting place for ideas, search terms, and other sources.
• Wikipedia, although itself not always a valid source, is useful both as a starting place and as a process guide to producing a text.

The third choice best offers the article’s main idea. I knew that the main idea would have something to do with the topic “Wikipedia,” because of the title.  But because the title included a question mark, I didn’t know if the main idea would end up being for or against Wikipedia.  Immediately after I skimmed, I thought that the main idea was stated directly in paragraph 12: “ There are productive ways to use Wikipedia. In fact, Wikipedia can be a good source in three different ways. Rather than a source to cite, it can be a source of (1) ideas, (2) links to other texts, and (3) search terms. ”  But when I read more fully, I realized that there were other things the author wanted me to understand, concepts more complex and nuanced than a direct “yes” or “no” answer to the title.  I found key ideas relating to the benefits of Wikipedia in paragraphs 2 and 4 in addition to 12. Paragraphs 2 and 4 discussed Wikipedia in terms of writing processes: the need to go back and revise, the co-production of an article’s text based on input from many sources (a “conversation”), and the concept of writing for a real audience. There are also a number of paragraphs that talk about the detriments of Wikipedia if used as a source.  Since there’s no single main idea sentence, I summarized the main concepts into a sentence that condensed and synthesized the article’s ideas into one main idea statement.

Identifying Main Ideas

A main idea is the most important thought on your topic. So let’s get into how to spot, and create, a really good one!

Explicit Main Idea

A main idea is the author’s controlling point about the topic.  It usually includes the topic and the author’s attitude or opinion about the topic.  To identify the main idea, ask yourself:

• Who or what is the paragraph about?  The answer is the topic .  The topic can be stated in just a few words.
• What does the author think about the topic?  The answer is the  point. The point can also be stated in just a few words.

Once you’ve identified these pieces, you can combine them to state the author’s main idea in a single sentence.

Topic + Point = Main Idea

Topic = the cool-down period

Point  = important parts of exercise workouts

( Topic + Point = Main Idea )

The cool-down period is an important part of an exercise workout .

Placement of Main Ideas & Topic Sentences

Often, but not always, the main idea of a paragraph is written as that paragraph’s topic sentence .  A topic sentence is a single sentence that states the topic and words that qualify the topic by revealing the author’s opinion about the topic or the author’s approach to the topic and also reveal the author’s thought pattern or organizational strategy. When you’ve identified both the main idea and the thought pattern, you can identify the topic sentence.

Main Idea = The cool-down period is an important part of an exercise workout

Thought Pattern  = several reasons

The cool-down period is an important part of an exercise workout for several reasons .

Main Idea +  Thought Pattern = Topic Sentence

Below are more examples of how to craft topic sentences.

General to Specific

The topic sentence is the one sentence that is general enough to include all the ideas in the paragraph.  Therefore, a topic sentence that begins a paragraph or appears within the first few sentences of a paragraph signals a move from general ideas to specific ideas.  

Specific to General to Specific

At times, an author begins a paragraph with details to stir the reader’s interest in the topic.  The flow of ideas moves from the specific to the general and back to the specific.

Specific to General

Sometimes, an author waits until the end of the paragraph to state the topic sentence and main idea.  This allows the details to build up to the main idea and is sometimes called “climactic order.”

Implicit Main Idea

Implicit main idea refers to a main idea that is not stated directly but is strongly suggested by the supporting details in the passage.  Many paragraphs in college textbooks do not provide a topic sentence, instead using supporting details to imply the main idea.  To determine the implied main idea, look at:

• The supporting details: facts, examples, descriptions, and explanations given
• The author’s thought pattern
• The author’s purpose

Read the sample paragraph below:

Egypt’s pyramids are the oldest existing buildings in the world.  These ancient tombs are also among the world’s largest structures.  The largest pyramid stands taller than a 40-story building and covers an area greater than that of ten football fields.  More than 80 pyramids still exist, and their once-smooth limestone surfaces hide secret passageways and rooms.  The pyramids of ancient Egypt served a vital purpose: to protect the pharaoh’s bodies after death.  Each pyramid held not only the pharaoh’s preserved body, but also all the goods he would need in his life after death.

1.The topic of the paragraph is pyramids

2. There are three groups of supporting details: age, size, and purpose

3.The author has organized the supporting details into “characteristics” or “traits” of the pyramids.

4.The author purpose seems to be trying to define a pyramid.

Implied Main Idea: Pyramids are structures with several distinctive traits.

Remember, the main idea must be broad enough to cover all the details in the paragraph without being so broad that it includes details not mentioned.

Finding the Main Idea

The main idea of a paragraph is the author's message about the topic. It is often expressed directly or it can be implied. Knowing how to find main ideas allows you to understand and think critically about what you're reading. And that benefits you regardless of your chosen profession.

Where Are The Main Ideas Found?

It is easy to identify a main idea that is directly expressed in the text. Main ideas are often found:

• at the beginning of paragraphs. The first sentence often explains the subject being discussed in the passage.
• in the concluding sentences of a paragraph. The main idea can be expressed as a summation of the information in the paragraph as well as a link to the information in the next paragraph.

The main idea is not always clearly stated.   It is more difficult to identify a main idea when it is inferred or implied. It can be implied through other words in the paragraph. An implied main idea can be found in several ways.

• Several sentences in a paragraph can imply the main idea by introducing facts about the topic before actually stating the topic.
• Implied ideas can be drawn from facts, reasons, or examples that give hints or suggestions concerning the main idea. These hints will be clues leading you to discover the main idea in the selected text.
• Try the passage below to see if you can pick out the main idea. "To many parents, the infant's crying may be mainly an irritation, especially if it continues for long periods. But crying serves important functions for the child as well as for the parents. For the child, crying helps improve lung capacity and the respiratory system. Perhaps more important, the cry serves as a signal of distress. When babies cry, they indicate that they are hungry or in pain, and this is important information for parents."

Use the hints below to determine the correct main idea of this paragraph.

After reading a paragraph ask, "What point is the author making in this passage?"

Ask the following questions:

• Who - Does this passage discuss a person or group of people?
• When - Does the information contain a reference to time?
• Where - Does the text name a place?
• Why - Do you find a reason or explanation for something that happened?
• How - Does this information indicate a method or a theory?

How To Determine If I Have Selected the Correct Main Idea of a Paragraph?

If you are able to summarize the information in the passage in your own words,you have absorbed the correct main idea. To accomplish this goal, try the steps listed below after reading a short section of your textbook.

• Write a short summary in your own words about what you have read.
• Does your summary agree with this general topic?
• Does your summary contain the same ideas being expressed by the author?
• Could you write a headline (or textbook subheading) that would express your summary in less than five words?

If you are able to rephrase your choice of a topic sentence into a question and then determine if the passage answers your question, you have been successful at selecting a main idea.

2.2: What is the Point? Thesis and Main Ideas

• Last updated
• Save as PDF
• Page ID 13716

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

Learning Objectives

• 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.

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?

Finding the Main Idea

Updated August 31, 2023

A commonly used reading comprehension strategy is to teach students how to find the main idea. But why does this strategy work? 

To support students’ understanding and to help lessen students’ cognitive demands, the research recommends that educators explicitly teach students about text structure. What Works Clearinghouse offers recommendations for improving reading comprehension in early readers. Specifically they suggest: “teach students to identify and use the text organizational structure to comprehend, learn, and remember content” (Shanahan et al, p. 17). They go on to assert that research related to effective strategies shows that students can retain and understand information better when they are taught how to “recognize the structure of a text” (Shanahan et al, p. 36). 

These recommendations and research demonstrate the effectiveness of explicitly teaching students to find the main idea. Learning to recognize text structure and to apply strategies to identify and generate topics, main ideas, and supporting details helps develop comprehension skills. As content becomes more challenging, effective comprehension strategies play an ever-more-essential role.

How Can I Locate the Main Idea?

Once you can find the topic, you are ready to find the main idea. The main idea is the point of the paragraph. It is the most important thought about the topic.

To figure out the main idea, ask yourself this question: What is being said about the person, thing, or idea (the topic)?

The author can locate the main idea in different places within a paragraph. The main idea is usually a sentence, and it is usually the first sentence. The writer then uses the rest of the paragraph to support the main idea.

Let’s use the paragraph below as an example. First find the topic, then look for the main idea.

Summer is a wonderful time to spend at West Beach. It is a beach with light- colored, soft sand. The coastline goes on for a long way and many people enjoy walking along it. Children like to play in the surf and walk along the rocks that are visible at low tide. This is a fun beach for people of all ages. 

In this paragraph:    

• the topic is  West Beach
• the main idea (what the writer is saying about the topic) is that summer is a wonderful time at West Beach

Here is another example:

The movie Apollo 13 was a blockbuster for the summer of 1995.   It is an exciting story about space exploration. In the movie, the astronauts get in trouble while they are trying to return to Earth. People in the audience are on the edge of their seats waiting to see what happens. What makes it even   more exciting is that it is a true story.  

In this paragraph:  

• the topic is the movie  Apollo 13
• the main idea is in the first sentence:  Apollo 13 was a blockbuster for the summer of 1995

While the main idea is usually in the first sentence, the next most common placement is in the last sentence of a paragraph. The author gives supporting information first and then makes the point in the last sentence.

Here’s a paragraph we can use as an example. Try to locate the topic and the main idea.

Most teenagers and young adults do not know what they want to do for the rest of their lives. It is a big decision. There are a number of things you can do to narrow the choices. For example you can take an interest test, do some research on your own about a career, try volunteer work in the field in which you are interested, or “job-shadow”, in which you spend a day with a person who is working in a field that interests you. These are just a few helpful ideas as you begin to choose a career. 

  In this paragraph:

• the topic is  jobs  or  career choices
• the main idea is a few ideas to help the reader choose a career

Finally, an author might put the main idea in the middle of a paragraph. The author will spend a few sentences introducing the topic, present the main idea, then spend the rest of the paragraph supporting it. This can make the main idea more difficult to find.

See if you can find the topic and main idea in the paragraph below.

The United States seems to be in love with the idea of going out to eat. Because of this,  a real variety of restaurants has come about specializing  in all kinds of foods. McDonald’s is the king of a subgroup of restaurants called fast-food restaurants. Chances are, no matter where you live, there is a McDonald’s restaurant near you. There are even McDonald’s in the Soviet Union. Now McDonald’s is trying something new. It is called McDonald’s Express and there is a test site in Peabody, Massachusetts. It is part of a Mobil gas station. This allows you to fill up with gas and fill up on food at the same time. What will they think of next?

In this paragraph:

• the topic is  McDonald’s 
• the main idea is in the middle of the paragraph, in the third sentence:  McDonald’s is the king of fast food

When writing a single-paragraph essay, it’s important to know what your point is and how you’re going to prove it, because unlike a traditional-length essay, you won’t have the space of several paragraphs to flesh it out. The main idea and support for the main idea should be carefully crafted in a single-paragraph essay so you can say what you need to say in the most direct and concise way.

Main Idea And Supporting Detail: Meaning

In a single-paragraph essay, the main idea is the writer’s position or principal concept, and the supporting details are the means by which they develop and prove that idea. This might sound similar to a thesis statement . That’s because a thesis statement should include the main idea and supporting details for an essay.

Remember, a thesis statement is a single declarative sentence that includes the main idea, or position on a topic, and mentions the way(s) you intend to prove or support that idea. A thesis acts as a blueprint for the body of your essay. It lays out the expectation for the audience of what your point is and how you intend to prove it.

If you’re writing a single-paragraph essay, you might be wondering whether you need to include a thesis statement. The short answer is, yes you do! In this case, because your essay will only be the length of a paragraph, the thesis statement will function the exact same way as a topic sentence for a regular paragraph.

A topic sentence functions much the same as a thesis statement. It is a single sentence, usually the first sentence of a paragraph, that introduces the main argument or idea for that paragraph. It’s a helpful technique so your audience knows the principal point of each paragraph because it is expressly stated.

It’s also useful as a way to organize your argument . Each piece of support for your main idea can serve as the topic sentence for an entire paragraph that develops that supporting detail in relation to the main idea. Or, in the case of a single-paragraph essay, the topic sentence is the thesis for the entire essay.

A single-paragraph essay should be concise and to the point. There is no room for filler language or information that is not absolutely necessary. Because of the length of a single-paragraph essay, it is important to state your main point at the very beginning.

In a single-paragraph essay you don’t need to spend much time providing background information on the topic. Your main objective is to express your main idea and support it with concrete details. You can assume your audience already has a working knowledge of the subject.

How To Organize The Main Idea And Supporting Details

There is a basic structure for a single-paragraph essay that is similar to that of the basic multi-paragraph essay. It includes the topic sentence (or thesis statement), at least two pieces of supporting information, concrete evidence for and commentary on the supporting information, and a conclusion. See the layout below.

Fig. 1 - How to organize support for main idea.

Topic sentence (thesis statement)

Body support 1

Concrete details

Body support 2

Closing statement

In a single-paragraph essay, the thesis statement will come first and usher in the main idea. It isn’t always possible to fit the main idea and a reference to the supporting details into a single sentence, but it is a good goal.

In Around the World in Eighty Days (1873) Jules Verne explores the themes of calmness and persistence with his character Phileas Fogg; Mr. Fogg remains calm in the face of extreme circumstances as he travels the world, and remains persistent to his goal despite many setbacks.

This example demonstrates how to include support for the main idea within a single sentence (i.e. thesis statement). In a single-paragraph essay, the segment following the thesis statement is considered the body of the essay. This is where you provide support for the main idea.

What Can Be The Support For The Main Idea?

For a single-paragraph essay, support for the main idea must be specific and brief; you won’t have the space of several paragraphs to expound on the details. Because of this, it’s especially important for your support to be effective.

Below are some of the most constructive pieces of information to include to support your main idea.

Facts and Data

Sometimes the best support of the main idea is simply stating relevant facts. If, for example, you’re discussing why bats are a positive addition to your outdoor living space, you might include that they like to eat mosquitoes. Remember, you’ll need to choose only the most relevant information to make your point in the fewest possible sentences.

Quotes are an effective way to prove a point in a very concise way. This is true whether you’re quoting a text you’re discussing, or quoting an expert or authoritative source on the subject.

An authoritative source is one that can be trusted because it is widely recognized in the field as authentic and/or expert.

Quotes taken from the text under discussion are effective because this is the primary source . Quoting the source directly is the best way to prove your point about a text.

Statistical evidence is numerical data organized to show a trend or some information about a particular subject. This is great evidence because it usually represents large numbers of participants or objects; the larger the group, the more reliable the information. Some statistics you could use in a one paragraph essay are percentages or statistics.

The best places to get statistical data are from government organizations and other trusted sources in the field.

Examples of Relevant Details

Examples are the best way to support your main idea. You can use examples from the text you’re referencing, real life experiences, or anything else that will expand the main idea.

How To Identify The Main Idea And Supporting Details

Identifying the main idea and its supporting details improves your reading and understanding of a text and its topic. Once you’ve identified these elements, you can follow the author’s logic through their use of examples or other support.

Fig. 2 - Neoclassical pillars represent support for main idea.

One way to quickly recognize the main idea is to use these tips:

Scan the title of the text

Look for significance in the pictures included

Note words and phrases that are repeated often

Summarize the text in your own words (in a sentence, if possible)

Ask yourself - what is this text mostly about?

Relationship Between The Main Idea And Supporting Details

The supporting details are not the main idea, but are the pillars that hold up the main idea. These details are kind of like an extension of the main idea, and so can be confused with it sometimes.

Supporting details are meant to offer evidence of the accuracy or truth of the main idea. They offer more specific information about the topic.

The main idea in an article about global warming is, “Global warming is the long-term warming of Earth’s overall temperature and is the most pressing issue facing humanity today.” That is the concept that will be discussed in the body of the article. The following sentence is an example of a supporting detail for that main idea, “Fossil fuels are burned, which produce gasses that trap heat on the earth’s surface.”

The sentence about fossil fuels should not be confused with the main idea of the article. It is a single point that the author is using to explain the concept of global warming and its danger to humanity. It supports the idea that global warming is a danger to the planet, and humanity.

More Examples Of The Main Idea And Supporting Details

Below are a few examples of a main idea and its supporting details. Think about how these interact with one another as you read them.

Main idea: People suffering from neuroticism experience anger, anxiety, self-consciousness, irritability and depression, but their complaints of further physical ailments have largely been discounted by physicians until recently.

Supporting detail a: Research now shows that neuroticism is linked to five physical ailments: arthritis, ulcers, asthma, heart disease, and headaches.

Supporting detail b: Similarly, there is evidence that people who display pessimistic behavior in their teens or twenties or more likely to become seriously ill or die in their forties.

Main idea: Mental illness has been explained in many different ways over the course of the last several hundred years.

Supporting detail a: In ancient times, irrational behavior was thought to be the result of demons or evil spirits.

Supporting detail b: The Greeks believed irrational behavior was an imbalance of body fluids, called “humors,” or some organs being misplaced in the body.

Supporting detail c: After a resurgence in the belief of demons thanks to the highly superstitious Middle Ages, the last one hundred years have finally seen a true medical acceptance and explanation of mental illness.

Can you think of any more supporting details for the two examples above? Use these, or come up with some ideas of your own for more practice.

Thesis Statements vs. Main Ideas

• Teacher Tips: How to Write Thesis Statements for High School Papers
• Explanation on Theme in Literature for Students

The thesis statement is a one-sentence statement that expresses the main idea of the essay. The thesis statement is an arguable statement that communicates the author’s stance on a topic to the reader. In order to better understand the differences between a thesis statement and main idea, it's important to understand the components of an essay. Essentially, it's not a “versus” situation because the thesis statement and main idea cannot exist without the other.

Purpose of the Thesis Statement

The thesis statement is the foundation of the essay because it tells the reader what the essay will be about and gives the essay direction. The goals of the thesis statement are to organize and development your argument and provide your reader with a road map or guide to your argument. The thesis statement should answer a question about the topic you are exploring as a writer. A good thesis statement will express only one main idea and will assert your conclusion about a topic.

Identifying the Main Idea

If you are given a topic to write about, it's important to first do your research and identify some main ideas associated with that topic. If you are writing about a piece of literature or specific work, you'll still need to do research but you will also need to read for key concepts or key ideas within that piece of writing first. Consider rereading the piece of literature to locate the main idea of the writer. Once you have located the main idea, you can then generate an opinion about the idea and create your thesis statement.

Developing the Main Idea

The topic of an essay is the subject, or what the essay is all about. An idea is what the writer says about the topic. The ideas include the main idea, which is then expressed in the form of a thesis statement. The main idea is not arguable like the thesis statement should be; it's simply an idea. Before writing, you should first develop the main idea because you cannot generate an arguable thesis statement about a topic until you have identified what you think of the topic.

Purpose of the Topic Sentence

The main idea of an essay is conveyed through the thesis statement and carried out through the topic sentences. An idea cannot be a statement, but a statement conveys an idea, hence the purpose of a thesis statement to state the point of an idea to convey to the reader in the development of an essay. Topic sentences also express the main idea. It's the first sentence of each subsequent paragraph in the essay and should be followed by supporting details, all supporting the topic sentence, which should support the main idea expressed in the thesis statement.

Identifying Topics, Main Ideas, and Supporting Details

Understanding the topic , the gist , or the larger conceptual framework of a textbook chapter, an article, a paragraph, a sentence or a passage is a sophisticated reading task.  Being able to draw conclusions, evaluate, and critically interpret articles or chapters is important for overall comprehension in college reading.  Textbook chapters, articles, paragraphs, sentences, or passages all have topics and main ideas.  The topic is the broad, general theme or message.  It is what some call the subject.  The main idea is the "key concept" being expressed.  Details , major and minor, support the main idea by telling how, what, when, where, why, how much, or how many.  Locating the topic, main idea, and supporting details helps you understand the point(s) the writer is attempting to express.  Identifying the relationship between these will increase your comprehension.

The successful communication of any author's topic is only as good as the organization the author uses to build and define his/her subject matter.

Grasping the Main Idea:

A paragraph is a group of sentences related to a particular topic, or central theme.  Every paragraph has a key concept or main idea.  The main idea is the most important piece of information the author wants you to know about the concept of that paragraph.

When authors write they have an idea in mind that they are trying to get across.  This is especially true as authors compose paragraphs.  An author organizes each paragraph's main idea and supporting details in support of the topic or central theme, and each paragraph supports the paragraph preceding it.

A writer will state his/her main idea explicitly somewhere in the paragraph.  That main idea may be stated at the beginning of the paragraph, in the middle, or at the end.  The sentence in which the main idea is stated is the topic sentence of that paragraph.

The topic sentence announces the general theme ( or portion of the theme) to be dealt with in the paragraph.  Although the topic sentence may appear anywhere in the paragraph, it is usually first – and for a very good reason.  This sentence provides the focus for the writer while writing and for the reader while reading.  When you find the topic sentence, be sure to underline it so that it will stand out not only now, but also later when you review.

Identifying the Topic:

The first thing you must be able to do to get at the main idea of a paragraph is to identify the topic – the subject of the paragraph.  Think of the paragraph as a wheel with the topic being the hub – the central core around which the whole wheel (or paragraph) spins.  Your strategy for topic identification is simply to ask yourself the question, "What is this about?"  Keep asking yourself that question as you read a paragraph, until the answer to your question becomes clear.  Sometimes you can spot the topic by looking for a word or two that repeat.  Usually you can state the topic in a few words.

Let us try this topic-finding strategy.  Reread the first paragraph under the heading Grasping the Main Idea .  Ask yourself the question, "What is this paragraph about?"  To answer, say to yourself in your mind, "The author keeps talking about paragraphs and the way they are designed.  This must be the topic – paragraph organization."  Reread the second paragraph of the same section.  Ask yourself, "What is this paragraph about?"  Did you say to yourself, "This paragraph is about different ways to organize a paragraph"?  That is the topic.  Next, reread the third paragraph and see if you can find the topic of the paragraph.  How?  Write the topic in the margin next to this paragraph.  Remember, getting the main idea of a paragraph is crucial to reading.

The bulk of an expository paragraph is made up of supporting sentences (major and minor details), which help to explain or prove the main idea.  These sentences present facts, reasons, examples, definitions, comparison, contrasts, and other pertinent details.  They are most important because they sell the main idea.

The last sentence of a paragraph is likely to be a concluding sentence. It is used to sum up a discussion, to emphasize a point, or to restate all or part of the topic sentence so as to bring the paragraph to a close.  The last sentence may also be a transitional sentence leading to the next paragraph.

Of course, the paragraphs you'll be reading will be part of some longer piece of writing – a textbook chapter, a section of a chapter, or a newspaper or magazine article.  Besides expository paragraphs, in which new information is presented and discussed, these longer writings contain three types of paragraphs: introductory , transitional , and summarizing .

Introductory paragraphs tell you, in advance, such things as (1) the main ideas of the chapter or section; (2) the extent or limits of the coverage; (3) how the topic is developed; and (4) the writer's attitude toward the topic.  Transitional paragraphs are usually short; their sole function is to tie together what you have read so far and what is to come – to set the stage for succeeding ideas of the chapter or section.  Summarizing paragraphs are used to restate briefly the main ideas of the chapter or section.  The writer may also draw some conclusion from these ideas, or speculate on some conclusion based on the evidence he/she has presented.

All three types should alert you: the introductory paragraph of things to come; the transitional paragraph of a new topic; and the summarizing paragraph of main ideas that you should have gotten.

Read the following paragraph and underline the stated main idea.  Write down in your own words what you are able to conclude from the information.

The rules of conduct during an examination are clear.  No books, calculators or papers are allowed in the test room.  Proctors will not allow anyone with such items to take the test.  Anyone caught cheating will be asked to leave the room.  His or her test sheet will be taken.  The incident will be reported to the proper authority.  At the end of the test period, all materials will be returned to the proctor.  Failure to abide by these rules will result in a failing grade for this test.

You should have underlined the first sentence in the paragraph – this is the stated main idea.  What can be concluded from the information is: If you do not follow the rules, you will automatically fail the test.  This concluding information is found in the last sentence.

You can't comprehend the subject matter if you haven't identified the topic, the main idea, and the supporting details.

How to Write an Essay Introduction (with Examples)   

The introduction of an essay plays a critical role in engaging the reader and providing contextual information about the topic. It sets the stage for the rest of the essay, establishes the tone and style, and motivates the reader to continue reading.

An introduction is the opening section of an essay, paper, or other written work. It introduces the topic and provides background information, context, and an overview of what the reader can expect from the rest of the work. 1 The key is to be concise and to the point, providing enough information to engage the reader without delving into excessive detail. 

The essay introduction is crucial as it sets the tone for the entire piece and provides the reader with a roadmap of what to expect. Here are key elements to include in your essay introduction: 

• Hook : Start with an attention-grabbing statement or question to engage the reader. This could be a surprising fact, a relevant quote, or a compelling anecdote. 
• Background information : Provide context and background information to help the reader understand the topic. This can include historical information, definitions of key terms, or an overview of the current state of affairs related to your topic. 
• Thesis statement : Clearly state your main argument or position on the topic. Your thesis should be concise and specific, providing a clear direction for your essay. 

Before we get into how to write an essay introduction, we need to know how it is structured. The structure of an essay is crucial for organizing your thoughts and presenting them clearly and logically. It is divided as follows: 2  

• Introduction:  The introduction should grab the reader’s attention with a hook, provide context, and include a thesis statement that presents the main argument or purpose of the essay.  
• Body:  The body should consist of focused paragraphs that support your thesis statement using evidence and analysis. Each paragraph should concentrate on a single central idea or argument and provide evidence, examples, or analysis to back it up.  
• Conclusion:  The conclusion should summarize the main points and restate the thesis differently. End with a final statement that leaves a lasting impression on the reader. Avoid new information or arguments. 

Here’s a step-by-step guide on how to write an essay introduction: 

• Start with a Hook : Begin your introduction paragraph with an attention-grabbing statement, question, quote, or anecdote related to your topic. The hook should pique the reader’s interest and encourage them to continue reading. 
• Provide Background Information : This helps the reader understand the relevance and importance of the topic. 
• State Your Thesis Statement : The last sentence is the main argument or point of your essay. It should be clear, concise, and directly address the topic of your essay. 
• Preview the Main Points : This gives the reader an idea of what to expect and how you will support your thesis. 
• Keep it Concise and Clear : Avoid going into too much detail or including information not directly relevant to your topic. 
• Revise : Revise your introduction after you’ve written the rest of your essay to ensure it aligns with your final argument. 

Here’s an example of an essay introduction paragraph about the importance of education: 

Education is often viewed as a fundamental human right and a key social and economic development driver. As Nelson Mandela once famously said, “Education is the most powerful weapon which you can use to change the world.” It is the key to unlocking a wide range of opportunities and benefits for individuals, societies, and nations. In today’s constantly evolving world, education has become even more critical. It has expanded beyond traditional classroom learning to include digital and remote learning, making education more accessible and convenient. This essay will delve into the importance of education in empowering individuals to achieve their dreams, improving societies by promoting social justice and equality, and driving economic growth by developing a skilled workforce and promoting innovation. 

This introduction paragraph example includes a hook (the quote by Nelson Mandela), provides some background information on education, and states the thesis statement (the importance of education). 

This is one of the key steps in how to write an essay introduction. Crafting a compelling hook is vital because it sets the tone for your entire essay and determines whether your readers will stay interested. A good hook draws the reader in and sets the stage for the rest of your essay.  

• Avoid Dry Fact : Instead of simply stating a bland fact, try to make it engaging and relevant to your topic. For example, if you’re writing about the benefits of exercise, you could start with a startling statistic like, “Did you know that regular exercise can increase your lifespan by up to seven years?” 
• Avoid Using a Dictionary Definition : While definitions can be informative, they’re not always the most captivating way to start an essay. Instead, try to use a quote, anecdote, or provocative question to pique the reader’s interest. For instance, if you’re writing about freedom, you could begin with a quote from a famous freedom fighter or philosopher. 
• Do Not Just State a Fact That the Reader Already Knows : This ties back to the first point—your hook should surprise or intrigue the reader. For Here’s an introduction paragraph example, if you’re writing about climate change, you could start with a thought-provoking statement like, “Despite overwhelming evidence, many people still refuse to believe in the reality of climate change.” 

Including background information in the introduction section of your essay is important to provide context and establish the relevance of your topic. When writing the background information, you can follow these steps: 

• Start with a General Statement:  Begin with a general statement about the topic and gradually narrow it down to your specific focus. For example, when discussing the impact of social media, you can begin by making a broad statement about social media and its widespread use in today’s society, as follows: “Social media has become an integral part of modern life, with billions of users worldwide.” 
• Define Key Terms : Define any key terms or concepts that may be unfamiliar to your readers but are essential for understanding your argument. 
• Provide Relevant Statistics:  Use statistics or facts to highlight the significance of the issue you’re discussing. For instance, “According to a report by Statista, the number of social media users is expected to reach 4.41 billion by 2025.” 
• Discuss the Evolution:  Mention previous research or studies that have been conducted on the topic, especially those that are relevant to your argument. Mention key milestones or developments that have shaped its current impact. You can also outline some of the major effects of social media. For example, you can briefly describe how social media has evolved, including positives such as increased connectivity and issues like cyberbullying and privacy concerns. 
• Transition to Your Thesis:  Use the background information to lead into your thesis statement, which should clearly state the main argument or purpose of your essay. For example, “Given its pervasive influence, it is crucial to examine the impact of social media on mental health.” 

A thesis statement is a concise summary of the main point or claim of an essay, research paper, or other type of academic writing. It appears near the end of the introduction. Here’s how to write a thesis statement: 

• Identify the topic:  Start by identifying the topic of your essay. For example, if your essay is about the importance of exercise for overall health, your topic is “exercise.” 
• State your position:  Next, state your position or claim about the topic. This is the main argument or point you want to make. For example, if you believe that regular exercise is crucial for maintaining good health, your position could be: “Regular exercise is essential for maintaining good health.” 
• Support your position:  Provide a brief overview of the reasons or evidence that support your position. These will be the main points of your essay. For example, if you’re writing an essay about the importance of exercise, you could mention the physical health benefits, mental health benefits, and the role of exercise in disease prevention. 
• Make it specific:  Ensure your thesis statement clearly states what you will discuss in your essay. For example, instead of saying, “Exercise is good for you,” you could say, “Regular exercise, including cardiovascular and strength training, can improve overall health and reduce the risk of chronic diseases.” 

Examples of essay introduction 

Here are examples of essay introductions for different types of essays: 

Argumentative Essay Introduction Example:  

Topic: Should the voting age be lowered to 16? 

“The question of whether the voting age should be lowered to 16 has sparked nationwide debate. While some argue that 16-year-olds lack the requisite maturity and knowledge to make informed decisions, others argue that doing so would imbue young people with agency and give them a voice in shaping their future.” 

Expository Essay Introduction Example  

Topic: The benefits of regular exercise 

“In today’s fast-paced world, the importance of regular exercise cannot be overstated. From improving physical health to boosting mental well-being, the benefits of exercise are numerous and far-reaching. This essay will examine the various advantages of regular exercise and provide tips on incorporating it into your daily routine.” 

Text: “To Kill a Mockingbird” by Harper Lee 

“Harper Lee’s novel, ‘To Kill a Mockingbird,’ is a timeless classic that explores themes of racism, injustice, and morality in the American South. Through the eyes of young Scout Finch, the reader is taken on a journey that challenges societal norms and forces characters to confront their prejudices. This essay will analyze the novel’s use of symbolism, character development, and narrative structure to uncover its deeper meaning and relevance to contemporary society.” 

• Engaging and Relevant First Sentence : The opening sentence captures the reader’s attention and relates directly to the topic. 
• Background Information : Enough background information is introduced to provide context for the thesis statement. 
• Definition of Important Terms : Key terms or concepts that might be unfamiliar to the audience or are central to the argument are defined. 
• Clear Thesis Statement : The thesis statement presents the main point or argument of the essay. 
• Relevance to Main Body : Everything in the introduction directly relates to and sets up the discussion in the main body of the essay. 

Writing a strong introduction is crucial for setting the tone and context of your essay. Here are the key takeaways for how to write essay introduction: 3  

• Hook the Reader : Start with an engaging hook to grab the reader’s attention. This could be a compelling question, a surprising fact, a relevant quote, or an anecdote. 
• Provide Background : Give a brief overview of the topic, setting the context and stage for the discussion. 
• Thesis Statement : State your thesis, which is the main argument or point of your essay. It should be concise, clear, and specific. 
• Preview the Structure : Outline the main points or arguments to help the reader understand the organization of your essay. 
• Keep it Concise : Avoid including unnecessary details or information not directly related to your thesis. 
• Revise and Edit : Revise your introduction to ensure clarity, coherence, and relevance. Check for grammar and spelling errors. 
• Seek Feedback : Get feedback from peers or instructors to improve your introduction further. 

The purpose of an essay introduction is to give an overview of the topic, context, and main ideas of the essay. It is meant to engage the reader, establish the tone for the rest of the essay, and introduce the thesis statement or central argument.  

An essay introduction typically ranges from 5-10% of the total word count. For example, in a 1,000-word essay, the introduction would be roughly 50-100 words. However, the length can vary depending on the complexity of the topic and the overall length of the essay.

An essay introduction is critical in engaging the reader and providing contextual information about the topic. To ensure its effectiveness, consider incorporating these key elements: a compelling hook, background information, a clear thesis statement, an outline of the essay’s scope, a smooth transition to the body, and optional signposting sentences.  

The process of writing an essay introduction is not necessarily straightforward, but there are several strategies that can be employed to achieve this end. When experiencing difficulty initiating the process, consider the following techniques: begin with an anecdote, a quotation, an image, a question, or a startling fact to pique the reader’s interest. It may also be helpful to consider the five W’s of journalism: who, what, when, where, why, and how.   For instance, an anecdotal opening could be structured as follows: “As I ascended the stage, momentarily blinded by the intense lights, I could sense the weight of a hundred eyes upon me, anticipating my next move. The topic of discussion was climate change, a subject I was passionate about, and it was my first public speaking event. Little did I know , that pivotal moment would not only alter my perspective but also chart my life’s course.” 

Crafting a compelling thesis statement for your introduction paragraph is crucial to grab your reader’s attention. To achieve this, avoid using overused phrases such as “In this paper, I will write about” or “I will focus on” as they lack originality. Instead, strive to engage your reader by substantiating your stance or proposition with a “so what” clause. While writing your thesis statement, aim to be precise, succinct, and clear in conveying your main argument.  

To create an effective essay introduction, ensure it is clear, engaging, relevant, and contains a concise thesis statement. It should transition smoothly into the essay and be long enough to cover necessary points but not become overwhelming. Seek feedback from peers or instructors to assess its effectiveness.

36 Writing the Essay Body: Supporting Your Ideas

Whether the drafting of a paragraph begins with a main idea or whether that idea surfaces in the revision process, once you have that main idea, you’ll want to make sure that the idea has enough support. The job of the paragraph body is to develop and support the topic. Here’s one way that you might think about it:

• Topic sentence : what is the main claim of your paragraph; what is the most important idea that you want your readers to take away from this paragraph?
• Support in the form of evidence : how can you prove that your claim or idea is true (or important, or noteworthy, or relevant)?
• Support in the form of analysis or evaluation : what discussion can you provide that helps your readers see the connection between the evidence and your claim?
• Transition : how can you help your readers move from the idea you’re currently discussing to the next idea presented? For more specific discussion about transitions, see the following section on “ Transitions .”

For more on methods of development that can help you to develop and organize your ideas within paragraphs, see “ Patterns of Organization and Methods of Development ” later in this text.

Types of support might include

Now that we have a good idea what it means to develop support for the main ideas of your paragraphs, let’s talk about how to make sure that those supporting details are solid and convincing.

Strong vs. Weak Support

What questions will your readers have? What will they need to know? What makes for good supporting details? Why might readers consider some evidence to be weak?

If you’re already developing paragraphs, it’s likely that you already have a plan for your essay, at least at the most basic level. You know what your topic is, you might have a working thesis, and you probably have at least a couple of supporting ideas in mind that will further develop and support your thesis.

So imagine you’re developing a paragraph on one of these supporting ideas and you need to make sure that the support that you develop for this idea is solid. Considering some of the points about understanding and appealing to your audience (from the Audience and Purpose and the Prewriting sections of this text) can also be helpful in determining what your readers will consider good support and what they’ll consider to be weak. Here are some tips on what to strive for and what to avoid when it comes to supporting details.

Breaking, Combining, or Beginning New Paragraphs

Like sentence length, paragraph length varies. There is no single ideal length for “the perfect paragraph.”  There are some general guidelines, however.

Some writing handbooks or resources suggest that a paragraph should be at least three or four sentences; others suggest that 100 to 200 words is a good target to shoot for.

In academic writing, paragraphs tend to be longer, while in less formal or less complex writing, such as in a newspaper, paragraphs tend to be much shorter. Two-thirds to three-fourths of a page—or seven to twelve sentences—is usually a good target length for paragraphs at your current level of academic writing.

The amount of space needed to develop one idea will likely be different than the amount of space needed to develop another. So when is a paragraph complete? The answer is: when it’s fully developed. The guidelines above for providing good support should help.

Signs to end a paragraph and start a new one:

• You’re ready to begin developing a new idea.
• You want to emphasize a point by setting it apart.
• You’re getting ready to continue discussing the same idea but in a different way (e.g., shifting from comparison to contrast).
• You notice that your current paragraph is getting too long (more than three-fourths of a page or so), and you think your writers will need a visual break.

Signs to combine paragraphs include:

• You notice that some of your paragraphs appear to be short and choppy.
• You have multiple paragraphs on the same topic.
• You have undeveloped material that needs to be united under a clear topic.

Finally, paragraph number is a lot like paragraph length. You may have been asked in the past to write a five-paragraph essay. There’s nothing inherently wrong with a five-paragraph essay, but just like sentence length and paragraph length, the number of paragraphs in an essay depends upon what’s needed to get the job done. There’s really no way to know that until you start writing. So try not to worry too much about the proper length and number of things unless those are specified in your assignment. Just start writing and see where the essay and the paragraphs take you. There will be plenty of time to sort out the organization in the revision process. You’re not trying to fit pegs into holes here. You’re letting your ideas unfold. Give yourself—and them—the space to let that happen.

🤔 main idea finder: why using it.

Students often need to analyze loads of literary works to synthesize data and present their findings in academic assignments. Thus, they read tons of articles and books every semester.

Such a hassle, isn’t it?

But the good news is that you can leave this activity out and relax, getting only the gist of every assigned text carefully prepared for you by smart software. It’s the main idea finder – a tool that has made thousands of students’ lives easier and can do the same for you. Using our app, you can easily process large volumes of data and use brief summaries to write reports, literature reviews, and well-grounded analyses.

What Is a Central Idea of a Text?

The central idea is the primary message the author tries to communicate in his text, whether a lengthy book or a short article. Summaries can be long or short, but any piece of literature also has a key point that can be summarized in a single sentence or statement.

How to Find the Main Idea?

At first, it might seem challenging to elicit one main idea in a text, especially if it's long and touches upon many issues. Still, the simplest way to do this is to answer a question, " tell what the author wanted to say in one short sentence. " You can also think of this task as explaining the content to a child in simple terms. The answer will soon surface.

How to Summarize the Main Idea of an Article?

If you were tasked with summarizing the literary work’s idea, focus on the key terms first . What was the subject of the authors’ analysis? What did they want to analyze? Did they succeed? Then produce a summary of the key idea based on the authors’ main focus and approach to that subject.

🆚 Central Idea vs. Theme: What Is the Difference?

The central idea is typically different from the literary piece's theme. The distinction can become clear if you approach the main idea as the topic of a book or an article. It can be elicited even from a title or an abstract, as these parts rarely contradict the rest of the content.

A theme, in turn, is about the meaning that lies under the surface of words and sentences. It is a moral message you can embrace only after careful study of the text and thinking it over.

To illustrate these points, let’s consider a couple of examples. For instance, when talking about The Catcher in the Rye , you will identify:

• Main idea : resistance to coming of age
• Theme : protection of innocence

If you approach Othello, you may note the following:

• Main idea : manipulation and jealousy
• Theme : trust

As you can see, the main idea is closely related to a literary work's theme. Yet, they are subtly different; the main idea refers to the plot more, while the theme concerns the story's moral and life lesson.

There are several effective techniques to find the text’s main idea quickly and correctly. The main helper in this task is a well-established structure of academic texts. It may give you a couple of pointers on where to look for, saving you time and effort. Let’s review these pro tips and see how they work in practice.

Step #1: Look for a Thesis Statement

As a rule, the authors place their central ideas at the end of the introduction. The final sentence of an introductory paragraph is referred to as a thesis statement.

A thesis serves as a roadmap for the entire text , clarifying what the author means to discuss and what point they will argue. Thus, if you find that statement, half of the work is done, as you have the main idea at your fingertips.

Step #2: Mind Topic Sentences

To produce a more extended summary of the author's key ideas, you should also pay attention to the topic sentences spread across the text. These are typically placed at the beginning of each new paragraph.

A topic sentence communicates the paragraph's main idea , while the following sentences are used to strengthen that point and provide additional evidence.

Step #3: The First and Last Sentence Matter

If you're unsure whether you've interpreted the main idea or topic sentence correctly, look at the final sentence of the paragraph as well.

A concluding sentence is a summary that should wrap up the main idea once more before proceeding to the next point. So, a joint analysis of the paragraph's opening and closing sentences will give you a clearer point for a summary.

Step #4: Summarize a Paragraph in One Sentence

Nothing works better than a one-sentence summary . No matter the length of your assigned reading, anything can be explained in one short sentence. Once you perform this exercise, the text’s main idea will surface without a problem.

Step #5: Search for Repeated Keywords

A more nuanced approach is to look for repeated words or their synonyms. Such simple linguistic analysis will also help uncover the main idea and underlying themes.

🔎 How to Find the Main Idea: Example

Finding the text’s main idea shouldn’t be hard if you know where to look for it. Let’s consider an excerpt from Dale Carnegie ’s How to Win Friends and Influence People as an exercise for main idea formulation. Here is the full fragment:

If you tell me how you get your feeling of importance, I'll tell you what you are. That determines your character. That is the most significant thing about you. For example, John D. Rockefeller got his feeling of importance by giving money to erect a modern hospital in Peking, China, to care for millions of poor people whom he had never seen and never would see. Dillinger, on the other hand, got his feeling of importance by being a bandit, a bank robber and killer. When the FBI agents were hunting him, he dashed into a farmhouse up in Minnesota and said, "I'm Dillinger!" Fie was proud of the fact that he was Public Enemy Number One. "I'm not going to hurt you, but I'm Dillinger!" he said. Yes, the one significant difference between Dillinger and Rockefeller is how they got their feeling of importance.

You can locate the main ideas in this fragment using several tips we've outlined above. Here's what you will see if you focus on the topic sentence:

If you tell me how you get your feeling of importance , I'll tell you what you are.

It shows that the fragment will be dedicated to how different people find their feeling of importance and how the latter affects their activities, self-perception, and overall character. Now, we can also take a closer look at the first and last sentences of the paragraph:

If you tell me how you get your feeling of importance , I'll tell you what you are. Yes, the one significant difference between Dillinger and Rockefeller is how they got their feeling of importance .

This approach confirms our initial finding about the “feeling of importance” as the author’s central idea in this paragraph. Dale Carnegie gives two distinct examples – a philanthrope and a criminal – to show that regardless of the person’s activity, the self-derived feeling of importance is central in shaping their characters.

You can also apply the technique of repeated words to elicit the key idea here. A quick review of the paragraph shows the following repeated phrases and their synonyms:

• How you get your feeling of importance
• Significant

So, these phrases show that the main idea is about a search for one's feeling of importance and its significant role in determining one's character, type of activities, and vocation.

🤖 Automatic Main Idea Finders: How Do They Work?

As you can see, eliciting key details and themes in a text is not that hard.

All you need to do is:

• Focus on the topic,
• Read the passage carefully to capture its gist.

But why do this manually and waste so much time if you can use an automatic central idea generator? This machine tool can help you identify the main points in the assigned text. This way, you will have concise summaries outlining the most vital statements, which can speed up your essay work. Let’s have a look at how such an app works.

The tools that can single out main ideas in large texts usually follow the extraction-based principle . The smart algorithm identifies key phrases and words labeled as important in the text, extracting and compiling them into a shorter textual variant. The system uses machine learning techniques that approach summary from the word/phrase classification perspective:

• Frequency distribution of specific words
• Topic words
• Latent semantic analysis
• Discourse-based text analysis
• Bayesian topic models
• Graph models

Besides, you need to indicate the expected length of the summary, which may also affect the scoring criteria and selection of particular words and phrases for the final summary compilation. This way, you receive a concise summarization of content without redundant details; it contains the author's core message.

We hope that this main idea finder will be useful for you. Please try other free tools we offer: summarizer , essay rephraser , paragraph reworder , and thesis finder .
