The word 玩具 is formed by combining two characters: 玩, which means "to play" or "amusement", and 具, which means "tool" or "implement". When fused, the concept is not merely the sum of its parts but creates a new, unified idea: an object whose primary purpose and inherent nature is for play. It is the conceptual fusion of the action (play) with a physical object (tool), resulting in the specific category of a "play-thing", or toy.
