Radical 石 · Stone Radical (Stone, rock, hard material)

Semantic Clue (形旁): 石 (Indicates that the action involves hard materials like stone, bone, or ivory being ground and polished.)

Phonetic Clue (声旁): 多 (original sound: duō / cuō)

A hard STONE (石) is repeatedly worked and refined by a process involving MANY (多) repeated strokes and motions, representing both physical grinding of bone and mental polishing of ideas.

  • 石 Stone / hard material
  • 多 Phonetic clue and indicator of multiple iterations
5. History
Liushu category: Phono-semantic (形声)

Origin: Originally combined the stone radical (石) referring to grinding tools used on hard objects like bone or ivory, and a phonetic element (多) providing the pronunciation cue.

Semantic Evolution: Shifted from the literal physical action of grinding and shaping animal bones or ivory into tools, to the metaphorical polishing of human skills, literature, and collaborative deliberation.

  • Frequently paired with 切 (qiē) in the classic phrase 切磋 to describe scholars sharpening each other's knowledge like stones grinding jade.
