Ngurmbur

Ngurmbur, also spelt Ngomburr or Ngumbur, is an extinct Australian Aboriginal language once spoken west of the South Alligator River in Australia's Northern Territory. It is poorly attested, known mainly from neighboring peoples' reports that it resembled Umbugarla along with a handful of recorded sentences and vocabulary, and it has sometimes been assumed, without certainty, to be a dialect of Umbugarla rather than a separate language.
