About

Formed as a phono-semantic compound, 膝 combines ⺼ (肉, 'flesh'), the semantic component common in body-part characters, with the phonetic 桼 (qī), the original character for 'lacquer'. This pairing of a general anatomical marker and a specific sound yields a dedicated grapheme for the knee joint. Throughout its textual history, the character has consistently denoted the knee without semantic drift, appearing in medical texts, martial arts descriptions, and everyday anatomical references to the joint connecting the thigh and lower leg.
