Assuming you meant to write "nominal definition," a nominal definition is a definition that assigns a name or label to a particular concept, object, or phenomenon. It is a definition that describes the meaning of a term or concept as it is commonly used or understood in everyday language or a specific context, rather than providing an exhaustive or precise explanation of the term's essence or underlying nature.
Nominal definitions are often used in fields such as linguistics, philosophy, and social sciences to establish a common understanding of key terms and concepts that are central to the discipline. They may also be used to distinguish between related concepts or to clarify the meaning of a term in a particular context.
