The Kypchaks were connected to each other by nomadism and agriculture, and lived in political, literary and cultural relations since modern times. Genetically, the Kyrgyz language belongs to the Kypchak group of Turkic languages. The Kypchak group is made up of about ten national languages, consisting of several semi-assistants. The Kyrgyz-Kipchak half-group includes Kyrgyz and Southern Altai. The «Divani Lugat-at Turk» and «Codex Kumanicus» written monuments created in the Middle Ages are unparalleled historical sources. Encyclopedist Mahmud Kashkari's dictionary «Divani lugat-at Turk» is the first work that divides Turkish languages into separate languages and language groups. The manuscript «Codex Cumanicus» or «Book of the Kipchaks» written in the XIII-XIV centuries contains the words and phrases of the Kypchak language. Songs, riddles, and blessings in the old Kypchak language are preserved in the monument. These material treasures are the common heritage of all modern Turkic peoples. Their language is a language separated from us by more than a thousand years. Since then, the language has been changed not only in terms of vocabulary and grammar, but also in terms of sound structure. At the present time, the world of dimension names found in written records is often found in folk works, historical records, dictionaries, historical novels, and colloquial language
