Mongolian Language

The Mongolian language (Mongol khel) is the language of most residents of Mongolia and of many of the Mongolian residents of the Inner Mongolia autonomous region of China, totalling about 5.7 million speakers. In Mongolia, the Khalkha dialect of Mongolian, written in Cyrillic, is predominant; in Inner Mongolia, the language is more dialectically diverse and written in the traditional Mongolian script.
The traditional script was developed as an adaption of the Uyghur script to write the Mongolian language. It was introduced by the Uyghur scribe Tatar-Tonga, who had been captured by the Mongols during a war against the Naimans around 1204. Mongolian sources often distinguish the early forms by using the term Uyghurjin script. Western sources tend to use this term as a synonym for all variations of the Mongolian script.
