The Role of Topic Sentences

28 April, 2016 - 11:25

Topic sentences make the structure of a text and the writer’s basic arguments easy to locate and comprehend. In college writing, using a topic sentence in each paragraph of the essay is the standard rule. However, the topic sentence does not always have to be the first sentence in your paragraph even if it the first item in your formal outline.

Tip

When you begin to draft your paragraphs, you should follow your outline fairly closely. After all, you spent valuable time developing those ideas. However, as you begin to express your ideas in complete sentences, it might strike you that the topic sentence might work better at the end of the paragraph or in the middle. Try it. Writing a draft, by its nature, is a good time for experimentation.

The topic sentence can be the first, middle, or final sentence in a paragraph. The assignment’s audience and purpose will often determine where a topic sentence belongs. When the purpose of the assignment is to persuade, for example, the topic sentence should be the first sentence in a paragraph. In a persuasive essay, the writer’s point of view should be clearly expressed at the beginning of each paragraph.

Choosing where to position the topic sentence depends not only on your audience and purpose but also on the essay’s arrangement, or order. When you organize information according to order of importance, the topic sentence may be the final sentence in a paragraph. All the supporting sentences build up to the topic sentence. Chronological order may also position the topic sentence as the final sentence because the controlling idea of the paragraph may make the most sense at the end of a sequence.

When you organize information according to spatial order, a topic sentence may appear as the middle sentence in a paragraph. An essay arranged by spatial order often contains paragraphs that begin with descriptions. A reader may first need a visual in his or her mind before understanding the development of the paragraph. When the topic sentence is in the middle, it unites the details that come before it with the ones that come after it.

Tip

As you read critically throughout the writing process, keep topic sentences in mind. You may discover topic sentences that are not always located at the beginning of a paragraph. For example, fiction writers customarily use topic ideas, either expressed or implied, to move readers through their texts. In nonfiction writing, such as popular magazines, topic sentences are often used when the author thinks it is appropriate (based on the audience and the purpose, of course). A single topic sentence might even control the development of a number of paragraphs. For more information on topic sentences, please see "Writing Paragraphs: Separating Ideas and Shaping Content".

Developing topic sentences and thinking about their placement in a paragraph will prepare you to write the rest of the paragraph.
