Definition

An extenstional definition is a definition that consists of a list of subordinate concepts. [1]

Notes

Extensional definitions are only to be used when intensional definitions are difficult to elaborate and the number of subordinate concepts to be enumerated is limited.

Example

For example: Theatened species are critically endangered species, endangered species or vulnarable species.
