Reconstruction:Proto-Austroasiatic/muəjʔ

• Proto-Austroasiatic: *muəjʔ ~ *moːjʔ (Sidwell, 2024, #AA049)
• Proto-Mon-Khmer: *muuj ~ *muəj (Shorto, 2006, #1495.A, B)

Proto-Aslian had alternate nasal onset. Vietic and Mang have stop codas that don't match with the rest. The Khasian lemmas (if indeed are reflexes of this root) show the loss of initial *m-.
