Nyawaygi language
The Nyawaygi language, also spelt Nyawaygi, Nywaigi, or Nawagi, is an extinct Australian Aboriginal language that was spoken in northeast Queensland, on the east coast of Australia.
Nyawaygi had the smallest number of consonants, 12, of any Australian language. It had 7 conjugations, 3 open and 4 closed, the latter including monosyllabic roots, and, in this regard, conserved a feature of proto-Pama–Nyungan lost from contiguous languages.
