A definition explains what a term or topic is by including three essential parts: the term being defined, the category it belongs to, and its distinguishing characteristics. The thesis statement of a definition paragraph should explain the purpose of the definition, rather than just identifying the term. When defining unfamiliar topics, it is helpful to compare them to familiar topics and explain how they differ from similar topics. Writing a definition essay should include a thesis stating the importance of understanding the defined term, devote a paragraph to each distinguishing characteristic, and provide sufficient details to make the topic understandable.
