Classification and division is a rhetorical style that, in essay format, takes a whole and splits it up into parts and then places the divided information into various categories. While you may see this rhetorical style used within a single paragraph, it’s not uncommon to write an entire essay using a classification and division format.
A classification and division essay combines two different techniques. First, you would divide a complex and difficult topic into subtopics for clarity and explanation purposes. Next, you would determine what categories are needed and what information fits into those categories. Think of a newspaper. All of the information is divided into different parts: news, advertisements, and classifieds. Then the information is classified into different categories. For example, news may be categorized as sports, international, local, lifestyle, etc.
