Sa'och language
Sa'och (, also, "Sauch") is an endangered, nearly extinct Pearic language of Cambodia and Thailand spoken only occasionally by a decreasing number of older adults. There are two dialects, one spoken in Veal Renh Village, Prey Nob District, Sihanoukville Province (formerly known as Kampong Som Province), Cambodia and the other in Kanchanaburi Province, Thailand. "Sa'och" is the Khmer exonym for the people and the language. The Sa'och, however, consider this label, which means "scarlet fever" or "pimply" in Khmer, pejorative and use the autonym "Chung" () to refer to themselves and their language.
