チャガタイ語
Middle Turkic languages, through the influence of Perso-Arabic after the 13th century, developed into the Chagatai language, a literary language used all across Central Asia until the early 20th century. After Chaghatai fell into extinction, the standard versions of Uyghur and Uzbek were developed from dialects in the Chagatai-speaking region, showing abundant Chaghatai influence. Uyghur language today shows considerable Persian influence as a result from Chagatai, including numerous Persian loanwords.
