The Mnong language (also known as Pnong or Bunong) (Bunong: ឞូន៝ង) belongs to the Austro-Asiatic language family. It is spoken by the different groups of Mnong in Vietnam and a Pnong group in Cambodia.
According to Ethnologue, four major dialects exist: Central, Eastern and Southern Mnong (all spoken in Vietnam), and Kraol (spoken in Cambodia). Within a dialect group, members do not understand other dialects. The Mnong language was studied first by the linguist Richard Phillips in the early 1970s.
Lê, et al. (2014:234-235) lists the following subgroups of Mnong and their respective locations.
