Tutong is an Austronesian language and belongs to the Rejang-Baram group of languages spoken in Brunei as well as Kalimantan, Indonesia, and Sarawak, Malaysia. Tutong is related to the Belait language and roughly 54% of the words come from a common root.
Today, many speakers of Tutong are shifting away from the traditional language and code-mix or code-shift with Brunei Malay, Standard Malay and English. The language has been given a vitality rating of 2.5 based on a scale of 0-6 that uses the measures of (1) rate of transmission to future generations, (2) level of official support and (3) geographical concentration of speakers. This means it is considered endangered.
Nonetheless, there is interest in revitalizing the language. Since 2012, a module has been taught in Tutong at Universiti Brunei Darussalam (UBD). Similarly, the Dewan Bahasa dan Pustaka (Brunei's Language Agency) published a Tutong-Malay, Malay-Tutong dictionary in 1991 and a word list of several Brunei languages in 2011.
