The Turki language is a Türkic literary language active from the 13th to the 19th centuries, used by different (predominantly but not exclusively) Türkic peoples. The Turki language developed on the Karluk (Karluk-Khorezm languages) basis, which was a result of interaction of the Karakhanid language with the local Türkic languages (gradual replacement of d-type language with a j-type language). The Karakhanid Karluk language was adapted for a cycle of works in Khorezm, where it was enriched by Oguz and Kipchak elements and turned into one of the medieval Türkic languages.
