Tambora language

Overall, the phonemic profile is consistent with many languages of eastern Indonesia: that is, to the east but not to the west of Tambora.

[1] Hok-hok 'sit' suggests verbal reduplication, but the only other verb, makan, is an obvious Malay loan.

Donohue suggests that sarone 'ten' ~ sisarone 'twenty' may reflect an earlier vigesimal system, possibly from sa- 'one' doh 'person' -ne (suffix), a common way of counting 'twenty' in the region.

[1] Donohue notes one word, taintu 'hand', which is plausibly connected to other Papuan languages, those of Timor and Alor to the east: Abui taŋ, Oirata tana, Kui tan.

[1] A number of words end in -(k)ong and -ore, and the former are semantically similar (ingkong 'sun', kóngkong 'day', mang'ong 'moon', kingkong 'star'), suggesting possible suffixes, though they might simply be coincidence.
