Abstract: The relevance of the study is due to the need for a comprehensive analysis of the process and result of the functional and functional-semantic transposition of linguistic units from nouns to the class of adverbs. The purpose of the work is to describe the stages and limits of transposition of instrumental case forms of nouns into the category of adverbs of compatibility/collection. The novelty of the approach lies in the use of the technique of oppositional analysis, which made it possible to establish that the degree of departure of different word forms and their groups from nouns and approach to adverbs is different. In certain contextual conditions, the same word form demonstrates, respectively, a core or peripheral noun, a hybrid and a peripheral non-substantive adverb. The indicated stages of the actual grammatical transposition of a word form into the category of adverbs with the semantics of a collection are found within the semantic zone of the original substantive lexeme. The limit of this type of transposition is the stage of peripheral adverbs, representing grammatical homonyms of the original forms of the instrumental case of nouns. It has been revealed that cases of word forms going beyond the semantic zone of the original lexeme during adverbialization are rare. Most often, with functional-semantic adverbialization, metaphorization of the adverbialized noun is observed, creating a favorable basis for its semantic separation from the original lexeme. Groups of nouns have been identified that demonstrate, in typical contexts, different numbers of stages of transposition into adverbs of compatibility. Each stage of adverbialization is determined by the syntactic conditions of speech – the syntagmatic environment of the word form, its functional load. In the zones of the periphery and core of adverbs, proper morphological changes in the structure of linguistic units are recorded.
