Nyangumarta, also writtenNjaŋumada,Njangamada,Njanjamarta and other variants, is a language spoken by theNyangumarta people and otherAboriginal Australians in the region ofWestern Australia to the south and east of Lake Waukarlykarly, includingEighty Mile Beach, and part of theGreat Sandy Desert inland to nearTelfer. As of 2021 there were an estimated 240 speakers of Nyangumarta, down from a 1975 estimate of 1000.^[2][3]

It has two dialects:Ngurlipartu^[4] andWanyarli.^[5] It is the most widely spokenAboriginal language in the town ofPort Hedland.

Nyangumarta is a member of theMarrngu branch of thePama–Nyungan languages. The other members of this group areMangarla andKarajarri, with which it shares features and vocabulary.^[6]: 5–9

Nyangumarta has two main dialects: Ngurlipartu, spoken in the southern, inland region,^[4] and Wanyarli, spoken in the northern, coastal region.^{[6]: 9–12 [5]}

Nyangumarta has a typical Australianphoneme inventory, with many consonant phonemes, including multiplelateral andrhotic phonemes, but few vowel phonemes.

There are 17 consonant phonemes in Nyangumarta, with five pairs ofhomorganic plosives and nasals.^[6]: 38

There are no voicing contrasts in Nyangmurta.

Allophones of the consonants tend to vary inmanner of articulation rather thanplace of articulation – e.g.plosives are usually voiceless word-initially, but voiced intervocalically and following nasals, and some plosives havefricative allophones.^{[6]: 40–41}

There are 3 contrastive vowels in Nyangmarta.^{[6]: 39–40}

Nyangmurta does not contrastroundedness orlength in vowels.

Monosyllabic words are permitted in Nyangumarta, but they must be at leastbimoraic, with short vowels and consonants each counting as one mora, and long vowels as two. All words must begin with a consonant, although, if the initial consonant is a glide followed by its matching vowel [i.e. a sequence of /ji/ or /wu/] the glide may be dropped by some speakers. Additionally, word-initial consonant clusters are not permitted in this language, except when a cluster is created through a process of vowelelision.^{[6]: 44–45}

Words in Nyangumarta are generally sorted into two major word classes: nominals, which take marking for case and number, and verbs, which take marking forTense, aspect, and mood. In addition to these two, there are also small closed classes of particles, exclamations, and clitics. As is typical of Pama-Nyungan languages, Nyangamurta uses suffixes to show case, person, number, TAM.^{[6]: 82–93}

Nyangumarta has three numbers: singular, dual, and plural, with dual and plural 1st person marked forclusivity. Unusually for a language of the Pilbara region,^[7] Nyangumarta has pronominal suffixes that attach to the verb in addition to independent pronouns.

Many Nyangumarta verbs are so-called complex verbs, formed out of a "pre-verb" (usually a nominal) plus an inflected stem, which combine to form a verb with a new meaning^{[6]: 99–102}

Some nominals are bound, and have no meaning independent of their use in complex verbs

Nyangumarta uses asplit ergative system of alignment: while case marking is done on an ergative-absolutive basis, pronouns (including pronominal marking on verbs) use a nominative-accusative system^{[6]: 120–124, 140, 322}

Simple verbs mostly fall into two major classes, NY-class and RN-class. The NY class is intransitive and the RN class is (mostly) transitive. There are also a few verb roots that encode a semantic distinction by alternating between the classes (e.g.jupa-NY, 'diminish' andjupa-RN, 'extinguish').[6]^{: 162–163}

Most Nyangumarta verbs are complex verbs, or verbs formed from derivation or compounding. Nyangumarta has a causative-ma-RN, an affective-ji-RN, and a verbalizer-pi-RN which adds no particular meaning to the verb. Of these,-ma-RN and-pi-RN can only be used with a nominal.^{[6]: 192–211}

Nyangumarta creates subordinate clauses through nominalization of verbs. There are fundamentally two types of subordinate clause: the purpose clause and the relative clause. Purpose causes denote why or for what purpose an action occurred, and are marked by dative marking on the nominalized verb.

Relative clauses denote either a shared time frame (T-type relative clause) or a shared argument (NP-type relative clause) between the main and subordinate clauses, and are marked by ablative marking on the nominalized verb. Additional case markers (dative, accusative, and locative) can be added on along with the ablative to produce more specific effects.

However, in many cases what is accomplished in other languages by subordination is accomplished in Nyangumarta with clause conjunction.[6]^{: 373–385}
