Central Uyghur, Southern Uyghur (Hetian, Hotan), Lopnur (Luobu), Akto Turkmen, Dolan. Central Uyghur comprises the varieties immediately north and south of the Tianshan mountains (Ili (Gulja, Yili, Taranchi), Urumqi (Urumchi), Turfan (Tulufan), Kumul (Hami), Aqsu (Akesu), Qarashahr (Karaxahar), Kucha (Kuqa). Kashgar (Kashi), Yarkand (Shache) and Yengisar (Yengi Hissar) are also generally considered part of Central Uyghur. Southern Uyghur comprises Khotan (Hetian), Keriya (Yutian), and Charchan (Qiemo). Modern standard Uyghur currently encompasses a number of local Turkic varieties whose linguistic affiliations are contested. These include Ainu (Eynu) [aib], Aqto Türkmen, Dolan, and Ili Turki (Taranchi) [ili]. Ainu is a southern Uyghur variety whose lexifier language is partly Persian; it is used as a jargon. Dolan is a slightly Mongol-inflected variety in the Teklimakan desert east of Kashgar. South of Kashgar, in Aqto county, 2,000 residents in the villages of Kösarap and Oytak use a Turkmen-inflected variety dubbed ‘Aqto Türkmen’ by some. Ili Turki (Taranchi) is indistinguishable from the Central Uyghur spoken in that Ili (Ghulja) area. Minor dialect differences between China, Kazakhstan, Kyrgyzstan, and Uzbekistan, overwhelmingly in loan vocabulary (2015 A. Dwyer).
