The word 拳击 is formed by directly combining two meaningful characters: 拳 (quán), meaning "fist", and 击 (jī), meaning "to hit" or "to strike". It creates a literal, visual compound where the first element identifies the primary tool (the fist) and the second element describes the core action (striking), resulting in the clear and immediate concept of "boxing" as the sport or act of fist-fighting.
