Proto-Central Pacific language

Proto-Central Pacific, originally spoken by Lapita settlers in Fiji three millennia ago, separated into a dialect network, consisting of what would become a western dialect (ancestral to Rotuman and western Fijian dialects) and an eastern dialect (ancestral to eastern Fijian dialects and Proto-Polynesian). Later, the dialects that remained in Fiji converged back, eventually becoming more similar, leading to the present-day Fijian language.[4]

The phonology of Proto-Central Pacific, according to Geraghty (1986),[5] are:
