The Brunei Malay language, also called Bruneian Malay language (Malay: Bahasa Melayu Brunei; Jawi: بهاس ملايو بروني), is the most widely spoken language in Brunei and a lingua franca in some parts of Sarawak and Sabah, such as Labuan, Limbang, Lawas, Sipitang and Papar.[2][3] Though Standard Malay is promoted as the official national language of Brunei, Brunei Malay is socially dominant and it is currently replacing the minority languages of Brunei,[4] including the Dusun and Tutong languages,[5] existing in a diglossic speech, wherein Brunei Malay is commonly used for daily communication, coexisting with the aforementioned regional languages and Malay creoles, and standard Malay used in formal speech; code switching between standard Malay and Brunei Malay is spoken in informal speech as a lingua franca between Malay creoles and regional languages. It is quite similar to Standard Malay to the point of being almost mutually intelligible with it,[6] being about 84% cognate with standard Malay.[7] Standard Malay is usually spoken with Brunei pronunciation.
