The Chamic languages, also known as Aceh–Chamic and Acehnese–Chamic, are a group of ten languages spoken in Aceh (Sumatra, Indonesia) and in parts of Cambodia, Thailand, Vietnam and Hainan, China. The Chamic languages are a subgroup of Malayo-Polynesian languages in the Austronesian family. The ancestor of this subfamily, proto-Chamic, is associated with the Sa Huỳnh culture, its speakers arriving in what is now Vietnam from Formosa.^[1]

After Acehnese, with 3.5 million, Jarai and Cham are the most widely spoken Chamic languages, with about 230,000 and 280,000 speakers respectively, in both Cambodia and Vietnam. Tsat is the most northern and least spoken, with only 3000 speakers.
