The Macro-Gunwinyguan languages, also called Arnhem or Gunwinyguan, are a family of Australian Aboriginal languages spoken across eastern Arnhem Land in northern Australia. Their relationship has been demonstrated through shared morphology in their verbal inflections. Many of the languages have a fortis–lenis contrast in plosive consonants. Lenis/short plosives have weak contact and intermittent voicing, while fortis/long plosives have full closure, a more powerful release burst, and no voicing.
