Yukagir verbs of single action on -re, -rey, requiring the indicators -sum and -sem (based on the language of the Tundra Yukagirs)

the article is devoted to the examination of productive cases of verbs indicating a one-off mode of action with the markers –SUM and –SEM. Special attention is paid to verbs formed from nouns, from verbal bases, and from complex verbal bases with a clearly distinguished marker of one-off mode of action using the affixes –re, –rey, which are used to denote an action that has occurred completely or has reached its culmination. In the present article, a comprehensive analysis of Yukaghir one-off action verbs with the suffixes –re, –rey, accompanied by the markers –sum and –s?m, is carried out, allowing for a deeper understanding of the peculiarities of the functioning of the tundra Yukaghir language. The relevance of the study is due to the rarity and insufficient examination of such forms in modern linguistics, which creates the need for a detailed morphological and syntactic analysis of these constructions. In the introduction, the necessity of studying verbs that indicate a one-off occurrence of an action is substantiated with the aim of identifying their specific semantic and syntactic characteristics. In the "Methods" section, the applied linguistic approaches are described, including corpus analysis, the comparative-typological method, and historical-etymological analysis, which allow for the identification of stable patterns in the usage of the suffixes –re, –rey and the markers –sum, –s?m. A detailed description is provided of the material drawn from a modern sample of texts in the tundra Yukaghir language, which ensures the objectivity of the study. The "Results" section is devoted to the analysis of the data obtained. It has been found that one-off action verbs marked with the suffixes –re, –rey demonstrate a stable connection with the markers –sum and –s?m, which play an important role in encoding temporal and aspectual meanings. Specific features of the morphological structure have been discovered, conditioned both by internal linguistic mechanisms and by external borrowings. The results obtained have allowed for a refinement of the existing system of typological classification of Yukaghir verb forms. The "Discussion" section focuses on the comparative analysis with similar linguistic phenomena in other Ural-Altaic languages, and it also substantiates the prospects for further research in the field of syntactic-morphological typology. The findings of the study lead to the conclusion that these forms make a significant contribution to the formation of the overall grammatical system of the tundra Yukaghir language, which appears to be important for the development of modern theories of language typology and the methodology for describing underrepresented languages.
