definers

Those who explain

Definers are people or things that define—that establish meaning, set boundaries, or determine the essential nature of something.

A dictionary is a definer of words; a leader may be a definer of policy.

The term often appears in discussions of identity and values: She rejected the traditional definers of success.

In technical contexts, definers may refer to elements in code or data structures that establish parameters or constraints.
