Many problems awaiting fundamental scientific research are enough in Kazakh linguistics. One of them is pronunciation as part of a whole word included in the root of the application. This phenomenon, which occurs during the development of the language, was based on the application's attempt to merge with the root. This is a linguistic pattern that has its own way of creation, signs and features. Obviously, we have the opportunity to find solutions to many confusing issues by identifying applications that fall into the root of a word in the language. For example, such issues as the word-formation function of endings, the phenomenon of habituation of adjuncts, the disappearance of the subordinate meaning, have not yet found an exhaustive solution. And one of the affixes used by the asset in our language – a comprehensive consideration of the integration of dependent unions into the root - will undoubtedly answer one of these questions. Obviously, the main function of conjunctions in the Turkic languages is to link words with each other and give them different grammatical meanings. But we know from various studies that some conjunctions that go beyond this pattern have both a word-formation function and the fact that they existed in the ancient times of the language. And at the expense of such unions, we risk studying the nature of the established, established words. There are many words in the Kazakh language that are not part of this word, do not divide them into each other. Complex and interesting words are currently in great contradiction between corresponding scientists.
