What is informal definition?

An informal definition is a definition that is given in informal language, such as colloquial language or everyday language. It is typically used to describe something in a more casual way, without the rigidity of formal definitions. Informal definitions are often used in conversation or informal writing as a way to provide clarity or elaboration on a concept or term. They may be more subjective and less precise than formal definitions, but they can also be more accessible and relatable to a wider audience. Informal definitions may rely on examples or anecdotes to illustrate a point or clarify a term, and they may include slang, humor, or cultural references.
