OK. Nothing is 'strictly Polynesian' as the language evolved over many years as the eastward migrations continued into Polynesia from the West. If you understand the Fijian language it shares many root words with Tongan and Samoan. The legends of the latter also make reference to Fijian contact. If you have ever been to Fiji try visiting the eastern leeward islands. Their language and culture is defintely western polynesian. Pottery shards from the Lapita migration discovered in Fiji pre-date anything else found in Polynesia. There are people on an island in the Solomon Islands who speak a Polynesian type language. I know this is basic stuff, and is the sort of thing that Tongans and Samoans often argue about (check out other threads on this forum). So I suppose the lesson we have to bear in mind when discussing language and culture in the South Pacific, is that we have to keep an open mind. Colonialism imposed boundaries upon us. Fijian is but one language in the whole family of 'Malayo-Polynesian' languages that includes Tongan, Samoan, Maori, etc etc. Nothing is 'strict'; everything in the Pacific is evolving. So an open mind is essential when discusiing language and culture.
