What is incidental definition?

An incidental definition is a definition that is given in passing or without intention. It is often included in a text to clarify the meaning of a word or phrase that might not be clear to the reader. Incidental definitions may be included in a dictionary entry or in the body of a scholarly article or book. They are different from formal definitions, which are specifically provided to describe a term or concept in a structured, precise way. Incidental definitions may be less formal, informal, or even humorous in tone, depending on the context in which they are used. They can be helpful in ensuring that the reader has a complete understanding of the text, and can aid in comprehension and communication.
