Warndarrang (waɳʈaraŋ), also spelt Warndarang, Wanderang, Wandaran, and other variants is an extinct Aboriginal Australian language in the Arnhem family, formerly spoken by the Warndarrang people in southern Arnhem Land, along the Gulf of Carpentaria. The last speaker was Isaac Joshua, who died in 1974, while working with the linguist Jeffrey Heath. Warndarrang is characterised by an unusually simplified nominal case system but highly intricate pronominal and demonstrative systems. It is a primarily prefixing language with agglutinating verbal complexes and relatively straightforward syntax.
