Gilyani Bitiasau Language

Gilyani Bitiasau (/giˈlja.ni biˈti.a.sau/) is an early Bitiasau language representing a relatively conservative ancestral stage from which Igniazi and Zinari later descend. It stands structurally closer to Igniazi than to Zinari, the latter having undergone substantial Tesian influence in phonology, lexicon, and administrative style. Gilyani preserves older lexical forms, fuller vowel realisations, and more transparent consonant sequences that were later reduced, fused, or regularised in the daughter languages. It has a predominantly open to lightly closed syllable structure, regular penultimate stress, and a compact vowel inventory /a e i o u/. The consonant system is simpler than that of later Igniazi, but already preserves conservative realisations such as /β ð ɣ ɾ/, while orthographic y continues to mark inherited palatalising sequences. In careful speech, sequences written sy, zy, ny, and gy remain overt clusters rather than merged reflexes.
