fist
👊 Bottom is 手 (hand); a hand rolled up tight = a fist
拳 stacks a 'roll up' element over 手 (hand). A hand curled and rolled up becomes a fist — hence fist and boxing. Sound quán rhymes with the 'rolled' top part juǎn.
拳 — hand 手 (bottom) + phonetic 龹
拳 is a semantic-phonetic compound. The bottom component 手 ('hand') gives the meaning, since a fist is formed by the hand. The top element 龹 supplies the sound, hinting at the reading quán. The original sense was 'closed hand, fist,' later extended to 'boxing' and martial arts.
