About
The character "颚", representing the jaw or palate, derives from its traditional form "顎", a phono-semantic compound combining the phonetic element "咢" with the semantic component "頁" denoting the head, thus etymologically linking it to cranial anatomy. Originally designating the bony structure of the mouth, its core meaning has remained stable in reference to anatomical parts essential for chewing and articulation, though it has occasionally extended to describe similar rigid or clamping forms in metaphorical contexts. The simplified form alters the semantic component from "頁" to "页", a graphical reduction that preserves the character's original structural logic and conceptual focus without shifting its fundamental sense.
