also from German, Malay, Portuguese and their own Austronesian languages (perhaps especially Kuanua, that of the Tolai people of East New Britain). This English-based pidgin evolved into Tok Pisin in German New Guinea (where the German-based creole Unserdeutsch was also spoken). It became a widely used lingua franca and language of interaction between rulers and ruled, and among the ruled themselves who did not share a common vernacular. Tok Pisin and the closely related Bislama in Vanuatu and Pijin in the Solomon Islands, which developed in parallel, have traditionally been treated as varieties of a single Melanesian Pidgin English or "Neo-Melanesian" language. The flourishing of the mainly English-based Tok Pisin in German New Guinea (despite the language of the metropolitan power being German) is to be contrasted with Hiri Motu, the lingua franca of Papua, which was derived not from English but from Motu, the vernacular of the indigenous people of the Port Moresby area. Official status Along with English and Hiri Motu, Tok Pisin is one of the three official languages of Papua New Guinea. It is frequently the language of debate in the national parliament. Most government documents are produced in English, but public information campaigns are often partially or entirely in Tok Pisin. While English is the main language in the education system, some schools use Tok Pisin in the first three years of elementary education to promote early literacy. Regional variations There are considerable variations in vocabulary and grammar in various parts of Papua New Guinea, with distinct dialects in the New Guinea Highlands, the north coast of Papua New Guinea, and islands outside of New Guinea. For example, Pidgin speakers from Finschhafen speak rather quickly and often have difficulty making themselves understood elsewhere. The variant spoken on Bougainville and Buka is moderately distinct from that of New Ireland and East New Britain but is much closer to that than it is to the Pijin spoken in the rest of the Solomon Islands. There are 4 sociolects of Tok Pisin: (meaning "talk of the remote areas") or (meaning "talk of the people of the remote areas"), (meaning "language of the villages") which is the traditional rural Tok Pisin, (meaning "talk of the schools") or (meaning "talk of the Towns") which is the urban Tok Pisin, and (meaning "language of the colonizers", unsystematically simplified English with some Tok Pisin words).
