The Bunak (also known as Bunaq, Buna’, Bunake) are an ethnic group that live in the mountainous region of central Timor, split between the political boundary between West Timor, Indonesia, particularly in Lamaknen District and East Timor. Their language, Bunak language, is one of the few on Timor which is not an Austronesian language, but rather a Papuan language like groups on New Guinea. It is usually put in the proposed language group Trans–New Guinea. They are surrounded by groups which speak Malayo-Polynesian languages, like the Atoni and the Tetum. According to Languages of the World (Voegelin and Voegelin, 1977), there were about 100,000 speakers of the language, split evenly between the two nations.
