Protean
adjective /ˈprəʊtiən/ — Able to change form readily — versatile and adaptable.
Definition
Able to change form or nature easily; tending or able to change in shape or character; extremely variable or versatile.
Beyond the definition
Proteus was a sea god who could change his shape at will — the only way to get truth from him was to hold him through all his transformations. Protean describes the capacity to be different things without losing coherence: the actor who disappears into roles, the writer who masters wildly different registers, the leader who reads every room differently.
Origin & history
From Proteus, the Greek sea god who could change shape — from Greek protos 'first'. He was sometimes called the 'Old Man of the Sea' and represented the uncatchable, transformative power of the ocean.
