Gunbarlang, or Kunbarlang, is an Australian Aboriginal language in northern Australia with multiple dialects.
Verbal morphology (rather than case marking or syntax) encodes a significant part of grammatical relations.
The verb includes obligatory agreement with its core arguments in the form of bound pronouns.
Subject prefixes form four mood series: positive indicative, "non-performative", future/intentional, and potential.
[11] Gunbarlang distinguishes five noun classes on demonstratives (M, F, plants, body-parts, and inanimate), but only four on other constituents (collapsing the latter two).
