The word 拳王 is formed by directly combining two meaningful characters: 拳 (quán), meaning "fist" or "boxing", and 王 (wáng), meaning "king" or "monarch". It creates a vivid, metaphorical image where the concept of a sovereign ruler is applied to the domain of boxing or fist-fighting. The mind naturally blends these ideas to form the composite concept of "the supreme champion or master of boxing", as if one reigns over the sport like a king over a kingdom.
