The Chamic languages, also known as Aceh–Chamic and Achinese–Chamic, are a group of ten languages spoken in Aceh (Sumatra, Indonesia) and in parts of Cambodia, Vietnam and Hainan, China. The Chamic languages are a subgroup of Malayo-Sumbawan 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 Borneo or perhaps the Malay Peninsula.
