The Purpose of Classification in Writing

The purpose of classification is to break down broad subjects into smaller, more manageable, more specific parts. We classify things in our daily lives all the time, often without even thinking about it. For example, cars can be classified by type (convertible, sedan, station wagon, or SUV) or by the fuel they use (diesel, petrol, electric, or hybrid). Smaller categories and the way in which these categories are created help us make sense of the world. Keep both of these elements in mind when writing a classification essay. It’s best to choose topics that you know well when writing classification essays. The more you know about a topic, the more you can break it into smaller, more interesting parts. Adding interest and insight will enhance your classification essays.

The Structure of a Classification Essay

The classification essay opens with a paragraph that introduces the broader topic. The thesis should then explain how that topic is divided into subgroups and why. Take the following introductory paragraph, for example:

The underlined thesis explains not only the category and subcategory but also the rationale for breaking the topic into those categories. Through this classification essay, the writer hopes to show the readers a different way of considering the state of New York.

Each body paragraph of a classification essay is dedicated to fully illustrating each of the subcategories. In the previous example, then, each region of New York would have its own paragraph. To avoid settling for an overly simplistic classification, make sure you break down any given topic in at least three different ways. This will help you think outside the box and perhaps even learn something entirely new about a subject.

The conclusion should bring all of the categories and subcategories back together again to show the reader the big picture. In the previous example, the conclusion might explain how the various sights and activities of each region of New York add to its diversity and complexity.

Writing a Classification Essay

Start with an engaging opening that will adequately introduce the general topic that you will be dividing into smaller subcategories. Your thesis should come at the end of your introduction. It should include the topic, your subtopics, and the reason you are choosing to break down the topic in the way that you are. Identifying the reason or rationale for breaking down the topic in a particular way builds the argument that will become your thesis. Use the following classification equation to craft your thesis statement: topic + subtopics + rationale for the subtopics = thesis.

The initial topic and the subsequent subtopics dictate the organizing strategy of a classification essay. Each body paragraph is dedicated to fully illustrating each of the subtopics. In a way, coming up with a strong topic pays double rewards in a classification essay. Not only do you have a good topic, but you also have a solid organizational structure to use as your outline while drafting. Be sure you use strong details and explanations for each subcategory paragraph that help explain and support your thesis. Also, be sure to give examples to illustrate your points.

Finally, write a conclusion that links all the subgroups together again. The conclusion should successfully wrap up your essay by connecting it to the topic initially discussed in the introduction.
