Ob-Ugric Institute of Applied Researches and Development, Khanty-Mansiysk, Russian Federation, [email protected] ABSTRACT Introduction: the article considers the change in the semantics and valence of Mansi and Khanty verbs with the preverb tāra / mukhty / muvty ‘through’ based on the material of the Ob-Ugric languages. Objective: to identify the features of the transition of verbs with the preverb tāra / mukhty / muvty from one lexical and semantic group to another. Research materials: verb sentences with the preverb tāra / mukhty / muvty ‘through’ ‘through’ of the Sosva dialect of the Mansi language and the Kazym and Surgut dialects of the Khanty language collected by the author from informants and extracted from dictionaries. Results and novelty of the research: for the first time, the most complete list of verbs with the preverb tāra / mukhty / muvty ‘through’ of different lexical and semantic groups has been revealed. It is established that this preverb is attached primarily to verbs with the semantics of action and movement. As a result, the number of valences of derived verbs either persists or decreases. Verbs of movement lose their locative valence; verbs of action retain their valence. The composition of the semantic group of verbs changes due to the compatibility of a verb with different types of subjects and objects (animate, inanimate). The results of the research may be in demand when comparing related and differently structured languages, as well as for writing the scientific grammar of the Khanty language. Key words: Ob-Ugric languages, preverb, valence, lexical and semantic group, verbs of action, verbs of movement Acknowledgments: the author expresses the gratitude to all the informants who speak the Khanty and Mansi languages.
