The official language of Brunei is Malay, but due to its British colonial past, English is widely spoken and understood in urban areas. A little Malay will come in handy in rural areas, as English proficiency is limited there. While all Bruneians are able to speak standard Malay, the local dialect of Malay is almost incomprehensible to other Malay speakers. Solely among the Malay-speaking states, Brunei also officially uses the Arabic script for Malay known as Jawi, although most signs are written both in Jawi and Roman letters. Nevertheless, the Roman alphabet is still the more commonly used script when writing Malay in Brunei.
The ethnic Chinese community in Brunei continues to speak a variety of Chinese dialects, including Hokkien, Teochew and several others.
