Tiwi 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 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.
