## Chinese
### Glyph origin

Historical forms of the character 齒 :
| Shang | Western Zhou | Shuowen Jiezi (compiled in Han) | Liushutong (compiled in Ming) |
| Oracle bone script | Bronze inscriptions | Small seal script | Transcribed ancient scripts |
| | Old Chinese |
| 祉 | *kʰlɯʔ |
| 址 | *kjɯʔ |
| 止 | *kjɯʔ |
| 趾 | *kjɯʔ |
| 芷 | *kjɯʔ |
| 沚 | *kjɯʔ |
| 阯 | *kjɯʔ |
| 齒 | *kʰjɯʔ |
| 紕 | *be, *pʰi, *kʰjɯʔ |
Pictogram (象形) – a mouth full of teeth. 之 (zhī) or 止 (zhǐ) was later added on top as a phonetic component.

### Etymology

Unclear. Not related to Tibetan མཆེ་བ (mche ba, “fang, tusk”), which is cognate with 齻 / 𱌺 (diān, “eyetooth”), but may be the same word as Proto-Min *kʰiᴮ (“tooth”). Another possibility is a derivation from an Austroasiatic etymon; Schuessler, 2007 (p.188) suggests a possible relationship to Khmer ខ្នាយ (khnaay, “tusk, spur”), as Austroasiatic medial /n/ is often deleted in loans.
