The Walmajarri people used to live in the Great Sandy Desert. Subsequent events took them to the cattle stations, towns and missions in the North and scattered them over a wide area. The geographical distance accounts for the fact that there are several dialects, which have been further polarized by the lack of contact and further influenced by neighbouring languages.
Warlmajarri has 4 syntactic cases: nominative, ergative, dative and assessory case. The cases assign different meanings to the noun phrases of a sentence. Therefore, the word order can vary quite freely. Subject, Object or Verb can appear initial, final, medial in sentence.
However, the second position of a sentence is always reserved for the Verbal Auxiliary. Sometimes referred to as a Catalyst, the Verbal Auxiliary indicates the mood of a sentence (similar to the English auxiliaries), but also cross-references its noun phrases. The person and number of the noun phrases in their syntactic cases are shown in the Verbal Auxiliary.
