Voice and Pluractionality in Äiwoo

This paper examines the uses of the prefix e- (ve-) in Äiwoo, an Oceanic language of the Temotu subgroup. It argues that the functions of this prefix can be subsumed under the label pluractionality, and that it is a likely reflex of the Proto-Oceanic prefix *paRi-. However, the distribution of the Äiwoo pluractional prefix is unusual in that it most common by far with intransitive position verbs; it can also occur on transitive verbs, but this is infrequent in the available data. This paper argues that this distribution is linked to the fact that Äiwoo has a distinct transitive actor voice which covers many of the typical pluractional functions with transitives. This is particularly clear when one compares Äiwoo (v)e- to its likely cognate (v)ö- in the Santa Cruz languages, which only applies to transitive verbs with detransitivizing functions; many of the functions of SC (v)ö- are covered by the actor voice in Äiwoo. The fact that Äiwoo appears to retain both a reflex of *paRi- and an actor voice/undergoer voice distinction may provide new perspectives on the history of *paRi-, since most Oceanic languages have lost the voice distinction; this may have led to an expansion of the functions of *paRi-, as suggested by the comparison between Äiwoo and the Santa Cruz languages.
