The vocabulary of Indonesian borrows heavily from regional languages of Indonesia, such as Javanese, Sundanese and Minangkabau, as well as from Dutch, Sanskrit, Portuguese, Arabic and more recently English. The official language of Indonesia is Indonesian (locally known as bahasa Indonesia), a standardised form of Malay, which serves as the lingua franca of the archipelago. Languages in Indonesia are classified into nine categories: national language, locally used indigenous languages, regional lingua francas, foreign and additional languages, heritage languages, languages in the religious domain, English as a lingua franca, and sign languages. The language most widely spoken as a native language is Javanese.
Most languages belong to the Austronesian language family, while there are over 270 Papuan languages spoken in eastern Indonesia. This figure indicates that Indonesia has about 10% of the world's languages, establishing its reputation as the second most linguistically diverse nation in the world after Papua New Guinea.
More than 700 living languages are spoken in Indonesia.
