Expresses a paragraph's main idea


Be relevant to the thesis. Primary support is considered strong when it relates directly to the thesis. Primary support should show, explain, or prove your main argument without delving into irrelevant details. When faced with a lot of information that could be used to prove your thesis, you may think you need to include it all in your body paragraphs. But effective writers resist the temptation to lose focus. Choose your examples wisely by making sure they directly connect to your thesis.


Be specific. The main points you make about your thesis and the examples you use to expand on those points need to be specific. Use specific examples to provide the evidence and to build upon your general ideas. These types of examples give your reader something narrow to focus on, and if used properly, they leave little doubt about your claim. General examples, while they convey the necessary information, are not nearly as compelling or useful in writing because they are too obvious and typical.

Be detailed. Remember that your thesis, while specific, should not be very detailed. The body paragraphs are where you develop the discussion that a thorough essay requires. Using detailed support shows readers that you have considered all the facts and chosen only the most precise details to enhance your point of view.

Example main idea: we need food in order to survive (so we can live).

Quickly recording your thoughts on paper will help you discover what you have to say about a topic. When writing quickly, try not to doubt or question your ideas. Allow yourself to write freely and unselfconsciously. Once you start writing with few limitations, you may find you have more to say than you first realized. Your flow of thoughts can lead you to discover even more ideas about the topic. Freewriting may even lead you to discover another topic that excites you even more.

Unified: All of the sentences in a single paragraph should be related to a single controlling idea (often expressed in the topic sentence of the paragraph).

Recall that when you prewrite you essentially make a list of examples or reasons why you support your stance. Stemming from each point, you further provide details to support those reasons. After prewriting, you are then able to look back at the information and choose the most compelling pieces you will use in your body paragraphs.

Before you can begin to determine what the composition of a particular paragraph will be, you must consider what is the most important idea that you are trying to convey to your reader. This is the "controlling idea," or the thesis statement from which you compose the remainder of the paragraph. In other words, your paragraphs should remind your reader that there is a recurrent relationship between your controlling idea and the information in each paragraph. The research problem functions like a seed from which your paper, and your ideas, will grow. The whole process of paragraph development is an organic one—a natural progression from a seed to a full-blown paper where there are direct, familial relationships in the paper between all of your controlling ideas and the paragraphs which derive from them.

The decision about what to put into your paragraphs begins with brainstorming about how you want to pursue the research problem. There are many techniques for brainstorming; whichever one you choose, this stage of paragraph development cannot be skipped because it lays a foundation for developing a set of paragraphs [representing a section of the paper] that describes a specific element of your overall analysis.

Given these factors, every paragraph in a paper should be:


2. Why knowing the main idea of the passage is important:

Conclusion: The final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea. For long paragraphs, you may also want to include a bridge sentence that introduces the next paragraph or section of the paper.

There are 4 effective ways to identify the main idea of a passage.

Without primary support, your argument is not likely to be convincing. Primary support can be described as the major points you choose to expand on your thesis. It is the most important information you select to argue for your point of view. Each point you choose will be incorporated into the topic sentence for each body paragraph you write. Your primary supporting points are further supported by supporting details within the paragraphs.

Decide whether the text is a topic or main idea.

Look at Mariah’s example. The instructor allowed the members of the class to choose their own topics, and Mariah thought about her experiences as a communications major. She used this freewriting exercise to help her generate more concrete ideas from her own experience.

What is the main topic of this passage?

There are many different ways you can organize a paragraph. However, the organization you choose will depend on the controlling idea of the paragraph. Ways to organize a paragraph include:

The main idea of the passage is – The origin of basketball

The hard-and-fast rule there was to create a new paragraph once the testimony, as transcribed, ran over 5-7 lines. It was more about readability than expressing ideas in a paragraph block. Actually, I kind of enjoyed the challenge of interpreting testimony and defining paragraphs on my own.
