This book is intended as a thorough description of the Jingulu language as spoken by the handful of speakers remaining in the Northern Territory ding the mid to late 1990s. The description is based on material which the author collected during three field trips from 1995 to late 1998. Chapter 1 focuses on the socio-historical context in which he language is spoken, including estimated of tradition area, number of speakers, and genetic and cultural affiliations. Chapter 2 is devoted to Jingulu phonology, from the phoneme inventory and phonotactics to a spectacular system of vowel harmony and some interesting facts on reduplication. Chapter 3 outlines the parts of speech of Jingulu as understood by the author, and argues for the particular labels and categories that the author assumes in following chapters. Chapter 4 discusses Jingulu syntax, from simple verbal and non-verbal predication to the encoding of dependent and conjoined clauses. Chapters 5 and 6 are expositions of the morphology of Jingulu nominal and verbal words respectively. Chapter 7 contains a few exemplary texts, glossed and translated into English. Through the grammar the author has preferred to provide more sentence examples rather than fewer (particular where the author was less than certain about the accuracy of his own description), to provide readers with a sense of what Jingulu sentences are actually like beyond what can be gleaned from prose description, and to provide future researchers with organised material with which to build their own hypotheses and analyses. This grammar contains no word list or dictionary. A separate Jingulu dictionary by the author is in preparation.
