Qashqai Turkic is one of the southwestern (Oghuz) Turkic languages in Iran, which has undergone profound changes at all language levels as a result of intense and long-term contact with Persian. This study investigates the changes that have occurred as a result of this contact in the strategies of combining clauses in the structure of complex sentences. These changes include changes in the strategies of coordination, as well as subordination strategies in relative, complement and adverbial clauses. In this study, by investigating and analyzing a written corpus consisting of seven story books, in addition to determining the change cases, an attempt has been made to quantify their extent and progress by quantitatively examining them, and the results of previous research in this field are re-evaluated. The theoretical framework used in this research is the code-copying model introduced by Lars Johanson and used in many researches related to contact linguistics in Turkic languages.
