Radical 木 · Wood Radical (tree, wood, wooden structure)

Semantic Clue (形旁): 木 (indicates that a trough or manger is traditionally made of wood)

Phonetic Clue (声旁): 曹 (original sound: cáo)

A wooden structure (木) shaped like the phonetic element 曹 forms a carved wooden trough or feeding manger (槽).

  • 木 Wood semantic indicator
  • 曹 Phonetic sound provider
Liushu category: Phono-semantic (形声)

Origin: Combined from 木 (wood) and 曹 (sound/phonetic), originally denoting a wooden feeding trough carved out of a log.

Semantic Evolution: Expanded from animal feeding troughs to any groove, slot, channel, or modern technical track.

  • The phonetic component 曹 originally represented two people speaking together, but here it solely provides the pronunciation.
