About
The character "龅", denoting protruding teeth, derives from its traditional form "齙", a pictophonetic construction combining the semantic radical "齒" (tooth) with the phonetic component "包". In its simplified iteration, "齒" is abbreviated to "齿" while "包" remains unchanged, maintaining the association where "包" hints at both pronunciation and the conceptual image of something bulging or enclosed, thus characterizing buck teeth. Historically, the character's meaning has consistently referred to dental protrusion without significant semantic shift.
