2.6 SELECTING 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.
1 The main idea is the central, or most important, idea in a paragraph or passage. It states the purpose and sets the direction of the paragraph or passage.
2 The main idea may be stated or it may be implied.
3 When the main idea of a paragraph is stated, it is most often found in the first sentence of the paragraph. However, the main idea may be found in any sentence of the paragraph.
4 The main idea may be stated in the first sentence of a paragraph and then be repeated or restated at the end of the paragraph.
5 The main idea may be split. The first sentence of a paragraph may present a point of view, while the last sentence presents a contrasting or opposite view.
