Although we refer all types of postpositions to one part of speech, there are large differences between the functions of each of them. It is visible both in terms of lexical meaning and grammatical purpose. This requires sufficient comparison of the types of postpositions with each other. Possessing stable theories developed in connection with the problems of other parts of speech, postpositions are one of the most important and urgent problems for Kazakh linguistics, and in Turkology. Obviously, the solution to the problems of the modern Kazakh language can be achieved only through a comparative study of the Turkic languages. The purpose of comparison of postpositions of Turkic languages is a broader understanding of the activities of postpositions in Kazakh language. It is true that the topic is fully revealed every time when the subject is studied. For this reason, this article is devoted to the problem of nominative cases in Turkic languages.
