The Khmuic languages are a branch of the Austroasiatic languages spoken mostly in northern Laos, as well as in neighboring northern Vietnam and southern Yunnan, China. Khmu is the only widely spoken language in the group.
Paul Sidwell (2015)[1] suggests that the Khmuic Urheimat (homeland) was in what is now Oudomxay Province, northern Laos.
The Khmuic languages are:
Similarly, Phuoc (Xinh Mul) and Kháng are also sometimes classified as Mangic, and Kháng is classified as Palaungic by Diffloth.
Bumang, formerly classified as Khmuic, is classified as a Palaungic language by Paul Sidwell. 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. (See Bit–Khang languages)
Khmuic language history and diversity are currently being researched by Nathaniel Hiroz.[2]
The interrelationships of these languages are uncertain. 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.[4]
Ilia Peiros (Peiros 2004:39) gives the following classification:
