- Change of Old Turkic *d to /y/, e.g. Uzbek åyåk 'foot', Uyghur quyruq 'tail'.
- Preservation of word-final */G/ after low vowels, e.g. Uyghur yaɣ 'fat', Uzbek tåɣ 'mountain'.
- Fortition of word-final */G/ after high vowels, e.g. Uyghur eyiq 'bear', Ili Turkic ellik '50'.
- Ili Turki occasionally exhibits rounding of word-final */G/ after low vowels (e.g. taw 'mountain'), which is a Kipchak feature. Because this is not consistent, and because lexical and other features are shared with Uyghur and Uzbek, I have placed it tentatively within the Turki branch.
