Class of things to which a defined word belongs
Logical definition:
Also called “real definition” by Richard Robinson.
Attempts to analyze things in the real world, as distinguished from words
Chief preoccupation of philosophers
Socrates explores the meaning of virtue and truth, seeking not to define the words but to understand the concepts that underlie them and the ways that people interact with these concepts.

Philosophers don’t.
Lexicographers do. Generally speaking, lexicographers define words based on what is most useful to the user.

All words within a definition must be explained.
The lexical definition should not contain words “more difficult to understand” than the word defined.
The defined word may not be used in its definition, nor may derivations or combinations of the defined word unless they are separately defined. (but one part-of-speech may be used to define another if all senses have been defined)
The definition must correspond to the part-of-speech of the word defined.
