Reconstruction:Proto-Sino-Tibetan/mjək

• Proto-Sino-Tibetan: *(s-)myəːk (Chou, 1972), *myikw (Coblin, 1986)
  • Proto-Tibeto-Burman: *s-myak ⪤ *s-mik (Matisoff, STEDT); *(s-)myəːk (Chou, 1972); *myikw (Coblin, 1986); *mya[a]k (LaPolla, 1987)

This root shows alternation between medial *ya and *i; here, this alternation will be notated as *jə.

In some languages (e.g. Burmish, Karenic) this word also means "face", a relationship perhaps reminiscent of Vietnamese mắt (“eye”) ~ mặt (“face”).
