A definition should not be too general or too specific. It should not include words from common usage that aren't relevant to the term being defined. It should also not be too obscure.

Definitions are an essential part of writing, as writers often use them to explain unfamiliar concepts. There are three types of definitions, but all attempt to explain a term.
