How did Arabic and Persian influence the Qarakhanid literary language?

Qarakhanid, which emerged in the 11th century in eastern Turkistan under the Qarakhanid dynasty, is recognized as the first Islamic Turkic literary language. While it was fundamentally based on pre-Islamic Turkic, the language was significantly influenced by Arabic and Persian.1

This development occurred as the Qarakhanids adopted Islam, a transition that generally facilitated the integration of Arabic and Persian elements into the literary traditions of early sedentary Turkic groups. As these languages were incorporated, they contributed to the evolution of the Qarakhanid literary style, reflecting the broader cultural and linguistic shifts occurring in the region during the Islamic period.12
