Voice and Valency Morphology in Äiwoo

This paper describes the function and distribution of main morphological markers voice valency in Oceanic language Äiwoo: undergoervoice suffixes -i, -nyi(i), -ive, -eâ, -nâ, circumstantial clitic =Cä. It compares these functions distributions to those reconstructed for Proto-Oceanic transitivizing morphemes *-i *akin[i], suggests pathways change that can account many present-day Äiwoo forms as being reflexes 3sg object *=a, though some formal differentiation remains unexplained. analysis implies has a Philippine-type symmetrical system with morphology, an unusual state affairs which implications our understanding transition from Proto-Malayo-Polynesian Proto-Oceanic.
