Brunei Malay
The local dialect, Melayu Brunei (Brunei Malay), also known as Kedayan, is the national language. It is spoken by about 266,000 people. It is also spoken as lingua franca in some parts of East Malaysia such as Federal Territory of Labuan, District of Limbang and Lawas (Sarawak) and District of Sipitang, Beaufort, Kuala Penyu and Papar (Sabah). It is expanding at the expense of the indigenous minority languages. Brunei Malay is quite divergent from standard Malay and the rest of the Malay dialects and is mostly mutually unintelligible with them.
