Kayardild is a moribund Tangkic language spoken by the Kaiadilt on the South Wellesley Islands, north west Queensland, Australia, with fewer than ten fluent speakers remaining. Other members of the family include Yangkaal (spoken by the Yangkaal people), Lardil, and Yukulta (Ganggalidda). It is famous for its many unusual case phenomena, including case stacking of up to four levels, the use of clause-level case to signal interclausal relations and pragmatic factors, and another set of 'verbal case' endings which convert their hosts from nouns into verbs morphologically.
