Turkic and Iranian speaking peoples have been living in vast parts of the Asia together or on neighbor geographies since at least end of the 6th century. The process of Turko-Iranian language contact began when Iranian speaking people Sogdians were incorporated into the First Turkic Khaganete and intensified after Islamization of Turks and Sogdians. Old Turkic dialects adopted many ‘general copies’ from Iranian languages especially from Sogdian and New Persian languages. In this study, approximately a hundred and twenty-four of ‘general copies’ will be enlisted and studied to provide some contribution to the field of TurkoIranian language contact via Diwān Lugāt al-Turk.
