The name Martuthunira, pronounced [maɽʊðʊneɻa] by native speakers, means "those who live around the Fortescue River".
It has many spelling variants, including: Maratunia, Mardadhunira, Mardathon, Mardathoni, Mardathoonera, Mardatuna, Mardatunera, Mardudhoonera, Mardudhunera, Mardudhunira, Mardudjungara, Marduduna, Mardudunera, Marduthunira, Mardutunera, Mardutunira, Marduyunira, Martuthinya, and Martuyhunira.
Under Carl Georg von Brandenstein's 1967 classification, Martuthunira was classed as a Coastal Ngayarda language, but the separation of the Ngayarda languages into Coastal and Inland groups is no longer considered valid.
Between vowels, the dental stop /t̪/ can become [d̪], [ð], [ð̞], [ɻ], [j], [w], or even simply a syllable break.
It occurs between vowels only in a handful of words, probably all loanwords, where it has a longer period of closure than the other stops [tː].
The laterals have prestopped allophones [ᶜʎ ᵗ̪l̪ ᵗl ʈɭ] when they occur in a syllable coda.
The alveolar rhotic /r/ is a tap [ɾ] between vowels, and a usually voiceless trill [r̥] finally.
