Language
Brunei Malay (Bahasa Melayu Brunei), or Kedayan (Kadazan), sometimes conflated as Brunei-Kedayan, is the national language of Brunei and a lingua franca in parts of East Malaysia. It is not the official language of Brunei, which is standard Malay, but is socially dominant and is replacing minority languages. It is quite divergent from standard Malay and is mostly mutually unintelligible with it.
Dialects are Brunei Malay, Kedayan and Kampong Ayer, which are almost close. The name Brunei Malay is used for the numerically and politically dominant Brunei people, who traditionally lived on water. Kedayan is the used for the land-dwelling farmers, and Kampong Ayer is used for the inhabitants of the river in and north of the capital.
