The Mongolian language (or Монгол хэл, pronounced [‘mongol ‘hæl]) is the official language of Mongolia and the best-known member of the Mongolic language family spoken in East-Central Asia. Although the Khalkha dialect which is written in Cyrillic is predominant in the country, in Inner Mongolia the language is dialectally more diverse and is written in the traditional Mongolian vertical script, derived from Uighur around 1204 by the Tangut man named Tata-tonga.
