Marrgu language (purple arrow), among other non-Pama–Nyungan languages (grey)
Marrgu had been assumed to be an Iwaidjan language like its neighbours. However, Evans (2006) has produced evidence that it was a language isolate, with possible connection to the extinct and poorly attested Wurrugu.

Marrgu had the three-vowel ( /a/, /i/, /u/) system typical of Iwaidjan languages (Evans 1998).
