The Bunak (also known as Bunaq, Buna', Bunake) people 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 is one of those on Timor which is not an Austronesian language, but rather a Papuan language, belonging to the Trans–New Guinea linguistic family. 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. Settlement area Today's settlement area of the Bunak people is located in the mountains of central Timor, ranging from the East Timorese town of Maliana in the north to the Timor Sea in the south, where both the Bunak and the Tetun communities often live side by side in coexistence. The Bunak people are isolated linguistically and socially, since the adjacent Kemak people to the north, the Mambai people in the east, the Tetun people in the south and west and the Atoni people speak to the west speak Malayo-Polynesian languages. Bunak is considered as being one of the Papuan languages, even though there are strong influences from the neighboring languages. The other Timorese Papuan languages are spoken in the east of Timor. Because of the language diversity in the region, the Bunak people are able to speak at least one of the Malayo-Polynesian languages fluently (in East Timor, Tetum is the lingua franca), while their surrounding neighbors rarely learn the Bunak language. In the hard-to-reach mountains, the townships of the Bunak people are relatively isolated from their neighboring communities. In East Timor, their area expands to the west of Manufahi District and in West Timor (Indonesia) towards the east of the Belu Regency and Malaka Regency. The Bunak people of East Timor live mainly in places like Bobonaro and Lolotoe in the town of Bobonaro District, Tilomar Subdistrict and Zumalai in the municipality of Cova Lima District, Cassa in the municipality of Ainaro District, and Betano and Same in the municipality of Manufahi District. In the western border area of Cova Lima District, the Bunak people form a minority among the Tetun people. However, many townships are mixed. Between Fohoren and the coast south of Suai mixed townships of Tetun and Bunak people are found. A
