Classification
Yidiny forms a separate branch of Pama–Nyungan. It is sometimes grouped with Djabugay as Yidinyic, but Bowern (2011) retains Djabugay in its traditional place within the Paman languages.Phonology
Vowels
Yidiny has the typical Australian vowel system of /a, i, u/. Yidiny also displays contrastive vowel length.Consonants
Yidiny consonants, with no underlyingly voiceless consonants, are posited. Dixon (1977) gives the two rhotics as a "trilled apical rhotic" and a "retroflex continuant".Grammar
The Yidiny language has a number of particles that change the meaning of an entire clause. These, unlike other forms in the language, such as nouns, verbs and gender markers, have no grammatical case and take no tense inflections. The particles in the Yidiny language: ''nguju'' - 'not' (''nguju'' also functions as the negative interjection 'no'), ''giyi'' - 'don't', ''biri'' - 'done again', ''yurrga'' - 'still', ''mugu'' - 'couldn't help it' (''mugu'' refers to something unsatisfactory but that is impossible to avoid doing), ''jaymbi'' / ''jaybar'' - 'in turn'. E.g. 'I hit him and he ''jaymbi'' hit me', 'He hit me and I ''jaybar'' hit him'. Dixon states that "pronouns inflect in a nominative-accusative paradigm… deictics with human reference have separate cases for transitive subject, transitive object, and intransitive subject… whereas nouns show an absolutive–ergative pattern." Thus threePronouns and deictics
Pronoun and other pronoun-like words are classified as two separate lexical categories. This is for morphosyntactic reasons: pronouns show nominative-accusative case marking, while demonstratives, deictics, and other nominals show absolutive-ergative marking.Affixes
In common with several other Australian Aboriginal languages, Yidiny is anAffixes and number of syllables
There is a general preference in Yidiny that as many words as possible should have an even number of syllables. It is for this reason that the affixes differ according to the word to which they are added. For example: the past tense affix is ''-nyu'' when the verbal root has three syllables, producing a word that has four syllables: ''majinda-'' 'walk up' becomes ''majindanyu'' in the past tense, whereas with a disyllabic root the final vowel is lengthened and ''-Vny'' is added: ''gali-'' 'go' becomes ''galiiny'' in the past tense, thus producing a word that has two syllables. The same principle applies when forming the genitive: ''waguja-'' + ''-ni'' = ''wagujani'' 'man's' (four syllables), ''bunya-'' + ''-Vn-'' = ''bunyaan'' 'woman's'. The preference for an even number of syllables is retained in the affix that shows a relative clause: ''-nyunda'' is used with a verb that has two or four syllables (''gali-'' (two syllables) 'go' + ''nyunda'' = ''galinyunda''), giving a word that has four syllables whereas a word that has three or five syllables takes ''-nyuun'' (''majinda-'' (three syllables) 'walk up' + ''nyuun'' = ''majindanyuun''), giving a word that has four syllables.Vocabulary
*bunggu. 'Knee,' but more extensively: 'That part of the body of anything which, in moving, enables the rest of the body or object to be propelled.' This is used of the hump in a snake's back as it wriggles, the swish point of a crocodile's tail, or the wheel of a car or tractor. * jilibura. 'Green (tree) ant'. It was squeezed, and the 'milk' it yielded was then mixed with the ashes of a ( blue gum tree), or from a ( quandong) or a bagirram tree, and the concoction then drunk to clear headaches. The classifier used for ants, , was used for all species, such as the ''gajuu'' (black tree ant) and (red ant), but never for a because it was different, having a medicinal use.References
