POC papian firewood, what is used to make a fire ⇫ ¶

Also Nukuoro lahhie ‘firewood’. Walsh and Biggs (1966) give Rarotongan vaʔie ‘firewood’, but this appears as vaie, with unexplained zero reflex for medial *f in their reported source (Savage 1962). Although the Oceanic forms can be regularly derived from PMP *pa-hapuy-an, and although POc preserved *api ‘fire’ it is unlikely that the morphological relationship between *api and *papian was apparent to speakers of POc, which had already undergone such a thorough morphological restructuring that many original morpheme boundaries were completely concealed from the average speaker. Except for the reported Maori variant fafia, all Polynesian reflexes show an irregular fronting of the final vowel, a change that presumably had already occurred in PPn, perhaps giving rise to doublets *fafie and *fafia.
