Kadazan Dusun

Kadazan Dusun, aka Bunduliwan (Dusun: Boros Dusun), is one of the more widespread languages spoken by the Dusun and Kadazan peoples of Sabah, Malaysia.

Under the efforts of the Kadazandusun Cultural Association Sabah, the standardized Kadazan-Dusun language is of the central Bundu-Liwan dialect spoken in Bundu and Liwan (now parts of the present-day districts of Ranau and Tambunan). Dusun Bundu-liwan's selection was based on it being the most mutually intelligible, when conversing with other Dusun or Kadazan dialects.
