Proto-Sino-Tibetan
Reconstruction
- Proto-Sino-Tibetan: ?
- Proto-Tibeto-Burman: *m-dzyway (Matisoff, STEDT); *m-jway (Matisoff, 1985)
Chinese 齒 / 齿 (chǐ), listed by Matisoff (STEDT) as a reflex, is probably not related. Other roots for "tooth": *sV-wa, *d-ŋa.
The double medial glides *-yw- in STEDT are posited solely to account for the palatalization in Tibetan མཆེ་བ (mche ba). The double medial reconstruction is not necessary, as *-w- as a medial is known to trigger the palatalization of preceding velar stops before front vowels in Tibetan;[1] a similar development could have caused the palatalization of the affricate in མཆེ་བ (mche ba).
