How to Do an Explanatory Paragraph

Explanatory paragraphs, also known as expository paragraphs, give an overall description of something that may be difficult to understand. These paragraphs are comprised of information that concisely and clearly explain a process or present other people's opinions or views in detail without being overly analytical or critical, according to Word-Mart.com, an online grammar and writing resource. Effective explanatory paragraphs are written smoothly and have fluidity.

Choose a theme or concept for the explanatory paragraph. Avoid focusing on an opinion; instead, choose a concept that you know about, such as a hobby, a character in a book or a pet. Ensure that the topic is understandable and not too complicated or confusing.

Write a topic sentence. This sentence, which is the first part of the paragraph, should set the tone for the remainder of the explanatory paragraph. When writing, ensure that you not only state the focus on the paragraph, but also include key words that will enable the rest of the sentences to center around these words. Just as an explanatory essay has a thesis statement, an explanatory paragraph should include a topic sentence.

Ensure that your paragraph has a logical progression of thought and that readers can easily follow your ideas and explanations, according to Purdue University's Online Writing Lab. Your sentences should also include evidential support and should connect to the logic of the topic sentence. Be creative when writing an explanatory paragraph, as this may help leave a lasting impression on readers.
