Inherited from Ottoman Turkish دیندار (dindar), from Classical Persian دِینْدَار (dīndār). By surface analysis, din + dar. Cognate with Old Uyghur 𐽸𐽶𐽺𐾀𐽰𐽾 (dyntʾr /dentar, dintar/, “priest, cleric, religioner”).
Practice speaking and memorizing "dindar" and many other words and sentences in Turkish.
