Mongolian language is one of oldest languages in the world. During the great conquest Mongolian language was near to Lingua France. There are some hypothesis that, Altai languages such as Mongolian., Turkish and Tunasian are not relative languages, but mutually reflected and interaction and Mongolian language is interaction and Mongolian language is independent language. So, researchers classifying Mongolian language into few sub-classes:
1. Mongolian language for Mongols from Mongolian Republic and Mongols from China’s Inner Mongolia.
2-3. Language for buryats and kalmyks from Russian
4-8. Language for uigurs, mongors and buukhans from China and mogols from afghanistan.
It is wrong idea, where language substituted by dialects, in dependence from political and administration division. IN the reality, only one Mongolian language. The Mongolian script has a great role in the formation and development of Mongolian language. This script had preserved a common literature language, because was formed for adequate service to all of dialects. Unfortunately, Russian Bolsheviks had attached to this common literary language. They had prohibited kalmyks, buriats and tuvas from 1921 to 1931 to use Mongolian language as a literary language. In 1944, Soviet Union had exported ulimatum like new script, based on krill script and Mongolian language development had oriented a wrong direction. During the “cultural revolution” inner Mongols had reactioned by Chinese “red defenders” in language.
There are many precious historical religion and literary creations was wrote with thousands year old Mongolian language and many of them preserved to our generation.
