チャガタイ語
Soviet and Uzbek sources hold that Nava'i significantly contributed to the development of the Uzbek language and consider him to be the founder of Uzbek literature. In the early 20th century, Soviet linguistic policy renamed the Chagatai language "Old Uzbek", which, according to Edward A. Allworth, "badly distorted the literary history of the region" and was used to give authors such as Alisher Nava'i an Uzbek identity.
