The Bardi language is currently spoken by fewer than 10 people. The language is a member of the Nyulnyulan family, a small non-Pama-Nyungan family in northwest Australia. This book is a reference grammar of the language. The 16 chapters include information on phonetics and phonology, nominal and verbal morphology, and syntax, as well as an ethnographic sketch of traditional life. A selection of texts is also included. It is the first published full study of a Nyulnyulan language.
