About
The character "膝", representing the knee, is a phono-semantic compound formed by combining the radical ⺼, a variant of 肉 meaning flesh or body part, to indicate its physical nature, with the component 桼 serving primarily as a phonetic element to suggest its pronunciation. This structure has persisted over time, with the phonetic component 桼, which independently denotes lacquer, providing a sonic clue while the semantic radical clarifies its association with the human body. The meaning of "膝" has remained consistently tied to the joint of the leg since its inception, and it is employed in various compound terms related to kneeling or the knee without significant semantic shift. The traditional form of the character, identical to its modern standard rendering, continues to reflect this etymological and structural composition.
