rook

word

Definition

A rook is a piece in chess that moves in straight lines along rows and columns. It can also mean a large black bird, similar to a crow, found in Europe and Asia.

Usage & Nuances

In chess, 'rook' is always the correct term (not 'castle' when referring to the piece, though 'castling' is a move). In everyday English, the bird meaning is rare and mainly used in British contexts. Don't confuse with the verb 'to rook' (to cheat someone), which is informal and unrelated.
