Sumbawa (Sumbawarese) is the language of the western half of Sumbawa Island, Indonesia, which it shares with 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. Neither the Bima nor the Sumbawa people have alphabets of their own for they use the alphabets of the Bugis and the Malay language indifferently.
