Ongan languages
Ongan, also called South Andamanese or Jarawa–Onge, is a small family of two languages, Önge and Jarawa, spoken in the southern Andaman Islands:
The two extant languages are:
Önge or Onge; 96 speakers (Onge) in 1997, mostly monolingual
Jarawa or Järawa; estimated at 200 speakers (Jarawa) in 1997, monolingual
A third language, Jangil, extinct sometime between 1895 and 1920, is reported to have been unintelligible with but to have had noticeable connections with Jarawa.
Classification
The Andamanese languages fall into two clear families, Great Andamanese and Ongan, plus one presumed but unattested language, Sentinelese. The similarities between Great Andamanese and Ongan are mainly of a typological and morphological nature, with little demonstrated common vocabulary. Linguists, including long-range researchers such as Joseph Greenberg, have expressed doubts as to the validity of Andamanese as a family. It has since been proposed that Ongan (but not Great Andamanese) is distantly related to Austronesian (Blevins 2007).
