Abstract
Currently, research on the Kipchak language has begun to be carried out in the field of Turkology. One of the reasons is that written monuments related to the Kipchak language are not found and studied. Monuments of Kipchak writing spread in different geographical territories with inscriptions from different countries. Kipchak served as an international language in the Middle Ages. A group of Kipchak written monuments refers to the Mamluk Kipchaks. They were written mainly in Arabic letters and were intended mainly for the local peoples of the lands of Egypt and Syria. Among the monuments of such writing were dictionaries, grammatical reference books, teaching aids. The reason for their writing was to teach the Kipchak language to the local population. The possession of political power by the Mamluk Kipchaks in the state created a need for the Kipchak language. In need, related works were written. A group of them disappeared, some of them were saved and reached us. Currently, one of the groups of Turkic languages is the Kipchak languages. The division of the Kipchak peoples into nationalities also led to the emergence of several national languages. The indigenous vocabulary of the modern Kazakh language consists of several layers. The vocabulary of the Kipchak language is a layer that forms the basis of the modern Kazakh language. Its study describes the historical development of the modern Kazakh language. In addition, the language of the monuments related to the Kipchak language of the Middle Ages has not been fully studied. Their introduction into academic circulation has been delayed. Today, these historical texts attract attention due to their value and the mysteries they still hold. Historical monuments of the Mamluks Kipchak script are considered to be of great research importance from the point of view of the modern Kazakh language.
