Tiwi ˈtiːwi is an Australian Aboriginal language spoken by the Tiwi people on the Tiwi Islands, within sight of the coast of northern Australia. It is one of about 10% of Australian languages still being frequently learned by children. Traditional Tiwi, spoken by people over the age of fifty by 2005, is a polysynthetic language. However, this grammatical complexity has been lost among younger generations. Tiwi has around one hundred nominals that can be incorporated into verbs, most of them quite different from the corresponding free forms. Tiwi has long been regarded as a language isolate due to its large scale of linguistic differences from other languages in the mainland Australia regions. However, recent research using historical linguistic techniques suggests that the Tiwi language might be under the Gunwinyguan family (a language family that consists of languages primarily spoken in North Central Australia). There are a number of name variations for the Tiwi language. Some of the variations were established by local Australian residents who lived in geographical regions and territories with close proximity with the Tiwi speakers, or have had close interactions with them for research work purposes. Other name variations of the language were coined by neighboring indigenous communities. Tunuvivi Tunuvivi was the initial term coined by the Indigenous members of the Melville and Bathurst islands. It is the original name for the Tiwi language itself, and has the meaning of 'people' or 'we the only people'. Meanwhile, the widely recognized name, Tiwi, was originally established by an anthropologist C.W.M. Hart in 1930 in order to have a discernible tribal name that can represent the Melville and Bathurst indigenous members. The term Tiwi was later accepted by the Melville and Bathurst islanders, and they have subsequently incorporated this name as a constituting part of their social identities. Wongak This name variation, Wongak, was used by the Iwaidja community to describe the Tiwi language.
