This volume is a descriptive analysis of Warlmanpa, a highly endangered language traditionally spoken northwest of the town of Tennant Creek, where most of the remaining speakers now live. This grammatical description is based on language work carried out by community members and linguists since 1952, and is the first published reference grammar of the language. The major areas of analysis include phonetics, phonology, morphology, and syntax. This volume also provides description of typologically notable features, including: a two-way stop contrast at each place of articulation; a complex second-position auxiliary system containing participant and tense/mood/aspect information; associated motion; and a lack of evidence for noun phrases. This volume lays the foundation for future Warlmanpa language work.
