[15] Kurmanji may have potentially been a literary language from the 10th to the 12th century with the formation of many Kurdish dynasties such as the Hasanwayhids, Rawadids, Ayyubids and especially under the Marwanids who commanded sizeable economic and cultural prosperity.

[16] The first known written attestation of Kurmanji is from the geographical work Mu'jam ul-Buldān by Yaqut al-Hamawi in which few words have been identified in a mostly indecipherable text.

[17] A growing interest in the use of Kurmanji in literature began from the 14th century on when Kurdistan had relative political stability and economic prosperity.

Furthermore, during his trips to Kurdistan, Evliya Çelebi praised the educational institutions of the Amedi and Akre regions and quoted a Kurmanji poem by local poet in his work.

Prominent scholars from this period, whose works are preserved today include Melayê Cizîrî, Feqiyê Teyran, Elî Teremaxî and Ehmedê Xanî.

[19] Phonological features in Kurmanji include the distinction between aspirated and unaspirated voiceless stops and the presence of facultative phonemes.

[32] During the end of the Ottoman era, Assyrians in Tur Abdin shifted from speaking their traditional Turoyo language to either Kurmanji or Arabic.
