In certain areas the influences of the Yakut and the Buryat languages are particularly strong. The influence of Russian in general is overwhelming (in 1979, 75.2 % of the Evenkis spoke Russian, rising to 92.7% in 2002). The Evenki language varies considerably among its dialects which are divided into three large groups:
• the northern
• the southern
• the eastern dialects
These are further divided into minor dialects.
The written language for Evenkis in the former USSR, based on the Latin alphabet, was created in 1931, and since 1937 it has been based on Cyrillic alphabet. In China, Evenki is written in the Mongolian script. University of Chicago linguist Lenore Grenoble, who has spent years studying the language, states that Evenki is one of Siberia's endangered languages
