The Khmuic languages /kəˈmuːɪk/ are a branch of the Austroasiatic languages spoken mostly in northern Laos, as well as in neighboring northern Vietnam and southern Yunnan, China.
Paul Sidwell (2015)[1] suggests that the Khmuic Urheimat (homeland) was in what is now Oudomxay Province, northern Laos.
Jerold A. Edmondson considers it to be most closely related to Khang.
Also, Quang Lam is a poorly attested language in Vietnam that is closely related to Kháng or Bit.
Ethnologue 19 classifies them as follows: A provisional classification at SEALang[3] keeps Mal–Phrai, but connects Khao with Khang instead of with Bit, treats Khuen as a dialect of Khmu': Chazée (1999), citing Diffloth & Proschan (1989), has the following: However, Gérard Diffloth now considers Pramic (i.e., all Khmuic languages except for Khmu) to be a separate Austroasiatic branch that has come under heavy influence from Khmu.
