The Hawu AKA Havu language, historically Sawu and known to outsiders as Savu or Sabu (thus Havunese, Savunese, Sawunese), is the language of Savu Island in Indonesia and of Raijua Island off the western tip of Savu. Traditionally classified as a Sumba language in the Austronesian family, it may actually be a non-Austronesian (Papuan) language. (See Savu languages for details.) Dhao, once considered a dialect, is not mutually intelligible with Hawu.
