Dusun language
Central Dusun, also known as Bunduliwan, is an Austronesian language and one of the more widespread languages spoken by the Dusun peoples of Sabah, Malaysia.
History
What is termed as Central Dusun and Coastal Kadazan are deemed to be highly mutually intelligible to one other; many consider these to be part of a single language.The language was among many other Sabahan vernacular languages suppressed under Mustapha Harun's assimilationist enforcement of Bahasa Malaysia across the state. Under the efforts of the Kadazandusun Cultural Association Sabah, in 1995, the central Bundu-Liwan dialect was selected to serve as the basis for a standardised "Kadazandusun" language. This dialect, spoken in the Bundu and Liwan valleys of the Crocker-Trusmadi ranges, was selected as it was deemed to be the most mutually intelligible when conversing with other "Dusun" or "Kadazan" dialects.

Grammar
Personal pronouns
Tindal Dusun has a Philippine-type focus system of syntax that makes one particular noun phrase in a sentence the most prominent. This prominent, focused noun phrase does not need to be the subject or the agent of the clause. In clauses with pronouns, the verbal morphology and the pronoun both indicate focus. If the verb carries actor focus morphology, the actor of the clause will therefore be a nominative pronoun. Any other noun phrase in the clause will necessarily take pronouns from a different set, as only one noun phrase can be in focus in any given clause."The "emphatic" pronouns are used alone or preposedly, either as answers or to stress the pronoun.
Sentence structure
A typical Dusun sentence is VSO.It is, however, possible for a grammatically correct Dusun sentence to be SVO.
