 However, the most widely spoken language in Brunei is Brunei Malay, which differs greatly from Standard Malay in areas like pronunciation, lexis and syntax.In addition, there are many other Malay dialects spoken by indigenous communities, such as Dayak and Iban.Usage of such Malay dialects has been on the decline due to assimilation of such ethnic culture with the mainstream culture; some varieties of these dialects are at risk of becoming extinct.
