Definition
To adapt is to change shape in order to keep living — the Latin adaptare means 'to fit to', and 'apt' still carries the fittedness. Species adapt to climates over generations; newcomers adapt to cities in months; a novel is adapted for the screen by surrendering the form that no longer fits. The word's quiet lesson is that survival belongs not to the strongest silhouette but to the one willing to revise it: what refuses the new shape forfeits the passage.

In TOEFL & IELTS
Core TOEFL biology vocabulary: organisms are 'well adapted to' their environments, and 'adaptation' is a passage-defining term. IELTS essays on technology and work lean on 'workers must adapt to'; in Speaking, 'adaptable' is a strong self-description. Spelling trap examiners love: adapt (adjust) vs. adopt (take up) — 'adopt a policy', but 'adapt to a situation'.
