and Doreen Miller. With the assistance of linguists from the University of Adelaide a number of printed and digital books have been produced for use in schools and in the wider community. In 2005 the Far West Languages Centre was established in Ceduna. The centre supports and promotes the use of the Wirangu language as well as other extremely endangered local languages, such as Gugada/Kokatha and Mirning. Phonology Vowels Wirangu has three phonemic vowels (a, i, u). Vowel length is not usually considered phonemic in Wirangu, as vowel length is normally short, although it is predictably long in all monosyllabic words (Wirangu 'ma' [ma:], 'wa' [wa:], 'mil' [mi:l], etc.), borrowings from other languages ('maatha' [ma:t̪a] < English "master"), and cases of initial consonant loss across phonological boundaries ('marna' + '(k)artu' = 'marnaartu' [maɳa:ʈu]). Consonants The consonantal phonemic inventory of Wirangu is very similar to that of many other Pama Nyungan languages, with six series of stops and nasals. Voicing is not phonemic in the Wirangu stop series, and many stops are either unvoiced or semivoiced. Wirangu also has two rhotics, an alveolar flap/trill and a more retroflex rhotic.
