The South Halmahera languages are the branch of Austronesian languages found along the southeast coast of the island of Halmahera in the Indonesian province of North Maluku.
Most of the languages are only known from short word lists, but Taba and Buli are fairly well attested.
They are not related to the North Halmahera languages, which are non-Austronesian. However, Ternatan influence is considerable, a legacy of the historical dominance of the Ternate Sultanate.
Reconstructions of subject markers and inalienable possessive markers for Raja AmpatâÂÂSouth Halmahera proto-languages according to Kamholz (2015). Note that V = vocalic conjugation, C = consonantal conjugation:
Proto-South Halmahera:
Proto-Central-Eastern South Halmahera:
Proto-Southern South Halmahera:
Most Gane and Taba dialects descending from Proto-Southern South Halmahera lost the inalienable possession suffixes. However, evidence from the Tahane dialect of Taba (Collins 1982) suggests that inalienable possession should be reconstructed for Proto-Southern South Halmahera, albeit in relic forms (compare Tahane mta-g "my eye", nim mta-m "your eye", and nim mta "his/her/its eye").
