Abstract. The study examines the category of the verb "transitional character of movement", manifested in terms of pronunciation. The purpose of the article is to unify the meaning of the category "transitional nature of movement" (A.Iskakov, M.Zholshayeva, N.Oralbayeva, Z.Akhmetzhanova, KTMukhamadi) with comments on the sound as a result of the analysis of verbal categories in the Kazakh language. To achieve this goal, it is planned to consider the meaning of the category "transitional nature of movement" in the ancient Turkic language, namely the use of this category in the Codex Cumanicus manuscript. The article presents a model for describing the differences of verbs included in the semantic group of the category "transitional character of movement" in the Kazakh language. The general and individual principles of the processes of semantic development of the category "transitional nature of movement" are defined. The description of the category "transitional nature of movement" in the modern Kazakh language complements the picture of the life process conveyed by the expression of movement. The authors of the article come to the conclusion that the specifics of the verb, expressing the transitional nature of the action, are better considered within the framework of a comparative historical grammar with indigenous languages. They come to the conclusion that an attempt to compare it with the Kazakh language due to the lack of features in unrelated groups of the language can distract attention from the study and prevent making the right conclusions. In the course of the study, based on the collected vocabulary material using the method of classification of lexico-semantic groups of the verb of the category "transitional character of movement", semantic analysis and grouping by differentiated features were carried out. The results of the research work can be guided in solving topical issues related to the field of historical grammar, expanding the field of general and applied language sciences, systematization of opinions related to the history of language.
