About
The character "膝", meaning knee, is composed of the meat radical "⺼" on the left, classifying it as a body part, and the phonetic component "桼" on the right, which originally denoted lacquer but in this context primarily provides sound. This structural arrangement has persisted, with the radical anchoring its semantic field to anatomy and the phonetic component reflecting historical pronunciation cues. The meaning of "膝" has consistently referred to the joint between the thigh and lower leg, maintaining this specific anatomical reference without notable semantic expansion or reduction over time.
