Araki, an unwritten Austronesian language belonging to the Oceanic subgroup, is now spoken by less than a dozen people in a small islet of Vanuatu; it is likely to disappear very soon. As the first ever publication about this language, the present study covers all that it has been possible to gather from it.The core of this book is a grammatical description of Araki: attention has been paid to its phonology and morphology, the inventory of syntactic categories, the internal organisation of noun and verb phrases, the semantics of aspect and mood, complex sentence construction, and many other topics which illustrate the originality of this language. A bilingual lexicon is also provided, as well as a selection of texts.
