Castling → The word 'castling' originates from the game of chess, where it refers to a specific move involving the king and a rook. The term is derived from the word 'castle', which in this context refers to the rook piece, and the suffix '-ing', indicating the action of performing the move. Thus, 'castling' describes the action of moving the king and rook in a particular manner during a chess game.
