Kipchak
Kipchak is a term used in both linguistics and ethnography to refer to a major branch of the Turkic language family and to the peoples historically associated with that linguistic group on the Eurasian steppe. In linguistic use, Kipchak denotes a group of related Turkic languages spoken across parts of Central Asia, the Volga region, and the northern Caucasus, with modern descendants in several states. The classification emphasizes shared features among these languages rather than implying a single modern language or nation.
Historically, the Kipchak designation is tied to a large confederation of Turkic tribes known as the Cumans
In contemporary usage, Kipchak most often appears in scholarly discussions of language classification and medieval ethnography
