Ongan languages


Ongan, also called Angan, South Andamanese or Jarawa–Onge, is a phylum of two Andamanese languages, Önge and Jarawa, spoken in the southern Andaman Islands.
The two known extant languages are:
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 is distantly related to Austronesian in a family called Austronesian–Ongan, but the proposal has not been well received by Austronesianists. Robert Blust finds that Blevins' conclusions are not supported by her data: Of her first 25 reconstructions, none are reproducible using the comparative method, and Blust concludes that the grammatical comparison does not hold up. Blust also discusses non-linguistic evidence against Blevins' hypothesis.

Reconstruction

The two attested Ongan languages are relatively close, and the historical sound reconstruction mostly straightforward:
Proto-Ongan*p*b*t*d*kʷ*k*j*w*c*m*n*l*r
Jarawap, bbtdhʷ, hhɡ, jjwcɟmnɲŋlr
Ongebbt, dd, rkʷ, hk, ɡɡ, Øjwc, ɟɟmnɲŋl, jr/j/l, Ø

Proto-Ongan*i*u*a*e*o
Jarawaiuae, ə, oo
Ongeiuae, ə, oo

*ə appears to be allophonic for *e before a nasal coda.

Grammar

The Ongan languages are agglutinative, with an extensive prefix and suffix system. They have a noun class system based largely on body parts, in which every noun and adjective may take a prefix according to which body part it is associated with. Another peculiarity of terms for body parts is that they are inalienably possessed, requiring a possessive adjective prefix to complete them, so one cannot say "head" alone, but only "my, or his, or your, etc. head".
The Ongan pronouns are here represented by Önge:
I, mym-we, ouret-, ot-
thou, thyŋ-you, yourn-
he, his, she, her, it, itsg-they, theirekw-, ek-, ok-

There is also an indefinite prefix ən-, on- "someone's". Jarawa does not have the plural series, but the singular is very close: m-, ŋ- or n-, w-, ən-. From this, Blevins reconstructs Proto-Ongan *m-, *ŋ-, *gw-, *en-.
Judging from the available sources, the Andamanese languages have only two cardinal numbers: one and two and their entire numerical lexicon is one, two, one more, some more, and all.
