The Leipzig-Jakarta list is studied in order to explore the nature of the Old Uyghur and Yakut language relations. Basically, the Old Uyghur and Yakut have similarities and differences due to the divergence of the Prototurkic language, which led to the formation of different classification types. However, the influence of the Old Uigur language on the Yakut phonetics is revealed in the form of the second type umlaut, which originated before the 9th century A.D. in the Circumbaikal region and predetermined the formation of the dialect system of the Yakut language.
