Abstract
Since the 50s of the XX century, fundamental research has been published to study the vocabulary, grammatical structure and sound system of modern languages, which are the heirs of the ancient Kipchak language - Kazakh, Karakalpak, Nogai, Bashkir, Tatar, Karaim, Kumuk, Karachay, Balkar, etc. The science of linguistics was formed in each of them. The sound, lexical and grammatical structure of the language system has become an independent form of phonetics, morphology, syntax, lexicology, phraseology, lexicography and other branches, which are subdivided into phonology, morphology, text syntax, terminology, onomastics, historical lexicology, lexicography, etc.). Thus, in the linguistics of a single branch of language, the language of medieval Turkic monuments was studied in terms of its relation to that language. Faced with the problems of linguistic Kipchak studies, the language of works written in the ancient Kipchak literary language in the Middle Ages is divided into today's Kazakh, Karakalpak, Bashkir, Tatar, Nogai, Kumuk, Karachay, Balkar, Kyrgyz and others, obliges to form the basis of comparative-historical lexicology of Kipchak languages, studied at the intersection of "history: language: culture" with each of the dozens of Kipchak languages.
