The Bunun language (Chinese: 布農語) is spoken by the Bunun people of Taiwan. It is one of the Formosan languages, a geographic group of Austronesian languages, and is subdivided in five dialects: Isbukun, Takbunuaz, Takivatan, Takibaka and Takituduh. Isbukun, the dominant dialect, is mainly spoken in the south of Taiwan. Takbunuaz and Takivatan are mainly spoken in the center of the country. Takibaka and Takituduh both are northern dialects. A sixth dialect, Takipulan, became extinct in the 1970s.
