The Malay language is an Austronesian language spoken not only by Malaysians but all Malay people who reside in the Malay Peninsula, southern Thailand, the Philippines, Singapore, central eastern Sumatra, the Riau islands, parts of the coast of Borneo, Cocos and Christmas Islands in Australia. It is also very similar to Indonesian, known locally as Bahasa Indonesia.In Malaysia, the language is officially known as Bahasa Malaysia, which translates as the "Malaysian language". The term, which was introduced by the National Language Act 1967, was predominant until the 1990s, when most academics and government officials reverted to "Bahasa Melayu," which is used in the Malay version of the Federal Constitution.
