About
The simplified character 颚 (traditional 顎) is a phono-semantic compound: the right side is the radical 页, meaning 'head' or 'face', while the left component 咢 indicates the pronunciation. It denotes the jaw and palate, the bony framework of the mouth that holds the teeth, in humans and many animal species. The character is used in anatomy and biology for the upper and lower mandibles, as well as the chewing apparatus of insects and other organisms. It is rarely used metaphorically, referring strictly to the physical structures involved in biting, chewing, and vocalization.
