The oil-rich sultanate of Brunei Darussalam is located on the northern coast of Borneo between the two Malaysian states of Sarawak and Sabah. Though the country is small in size and in population, the variety of language use there provides a veritable laboratory for linguists in the fields of Austronesian linguistics, bilingual studies, and sociolinguistic studies, particularly those dealing with language shift. This useful reference is divided into three sections: one on varieties of the Malay language used in the country, one on other indigenous languages, and one on the role and form of the English used there. Contributors to the collection include Bruneian scholars as well as established experts in the fields of Austronesian linguistics, sociolinguistics studies, and the description of new varieties of English.
