Indonesian ( ) is the official and national language of Indonesia. It is a standardized variety of Malay, an Austronesian language that has been used as a lingua franca in the multilingual Indonesian archipelago for centuries. Indonesia is the fourth most populous nation in the world, with over 270 million inhabitants—of which the majority speak Indonesian, which makes it one of the most widely spoken languages in the world.
