Sumbawa (Sumbawan: Basa Semawa, Indonesian: Bahasa Sumbawa) or Sumbawarese is a Malayo-Polynesian language of the western half of Sumbawa Island, Indonesia, which it shares with speakers of Bima. It is closely related to the languages of adjacent Lombok and Bali; indeed, it is the easternmost Austronesian language in the south of Indonesia that is not part of the Central Malayo-Polynesian Sprachbund. The Sumbawa write their language with their own native script commonly known in their homeland as Satera Jontal and they also use the Latin script.
