About
The character "齿" originated as a pictograph depicting teeth within a mouth, which over time stylized into the traditional form "齒", structured with "止" as a phonetic component above a mouth enclosure. The simplified form "齿" preserves the "止" element while simplifying the lower section. Its primary meaning of "tooth" has remained consistent, but it later expanded to denote gear teeth and, metaphorically, age in certain contexts.
