The word 拳头 (quántou, meaning "fist") is formed through a direct and vivid conceptual combination of its two component characters. The first part, 拳, by itself already means "fist" or "boxing", depicting a clenched hand. The second part, 头, means "head". When combined, they create the image of the "head of the hand", visually and functionally describing the prominent, rounded knuckle cluster that forms the striking part of a clenched fist, much like a head atop a body.
