What is nominal definition?

Nominal definition is a process of defining a concept or a term by providing its name or label. It is the simplest type of definition used mainly in everyday language and communication. Nominal definitions are often used when people have a shared understanding of a term or concept, such as animal or chair.

Nominal definitions are not always precise and clear, and they may not provide a complete or accurate understanding of a term or concept. Therefore, when a term or concept is important and needs to be fully understood and analyzed, nominal definitions are usually not enough. In such cases, more precise and comprehensive definitions are needed, such as operational and conceptual definitions.

Nominal definitions are also sometimes called lexical definitions, as they simply provide an explanation of the symbols or words used to represent a term or concept. The main purpose of nominal definitions is to establish a common vocabulary and language among people, so they can communicate effectively and share ideas and knowledge.
