Transpositional transformations of the adverbialized instrumental case of a name in the nuclear adverbs’ zone

INTRODUCTION. The study of the transitivity and syncretism’s phenomena at different levels of the language system is one of the urgent modern linguistics’ tasks. The relevance of the study is due to the need for a the stages’ and limits’ comprehensive analysis of the substantive word forms’ adverbial transposition, as well as the interaction features of grammatical and semantic in syncrets representing different stages of adverbialization. The purpose of the study is to deduce the signs and the limit of the functional–semantic transposition of the creative case without a preposition into the adverbs class. MATERIALS AND METHODS. The research material used is sentences from the National Corpus of the Russian Language and the authors’ own examples. In the course of the analysis of linguistic units, methods of oppositional analysis and indexing, elements of component, transformational and distributive analysis are used. RESULTS AND DISCUSSION . When analyzing the types of substantive word forms’ use in the adverbialization context different degrees (stages) of their departure from nouns and approximation to adverbs are revealed. The focus is on word forms such as “next”, explicating the core zone of the substantive adverbs. CONCLUSION. When indexing the functional and semantic adverbialization degrees of the word form “next”, it is found that it demonstrates in the area of the core of adverbs 0 % compliance with the original nuclear noun and 73 % compliance with the substantive nuclear adverbs (“gift”). The results obtained can be used in the quantitative study of the adverbialization degrees of other nonprepositional nouns’ forms in the Russian language, as well as in the general problems development of the transposition and syncretism theory.
