The Chagatai language is Finno-Urgic.
 His fame is attested by the fact that Chagatai is sometimes called "Nava'i's language"
 Virtually all other Turkic languages have a history of being written with an alphabet descended from Kona Yziq, however, due to various writing reforms conducted by Turkey and the Soviet Union, many of these languages now are written in either the Latin script or the Cyrillic script
