Part-of-speech homonyms as a consequence of the step-by-step transposition of the instrumental case of nouns into an adverb

The relevance of the work is associated with the need to develop criteria for differentiating functional and functional-semantic homonyms generated by the mechanism of adverbial transposition of the instrumental case of nouns. The novelty of the study is due to the development of criteria for differentiating, on the one hand, nouns, and on the other hand, adverbs arising on their basis. The purpose of the work is to study the features of nouns and adverbs that allow differentiating grammatical and lexical-grammatical homonyms. The object of analysis is substantive word forms involved in the process of adverbialization, the subject of consideration is the stages and features of their adverbial transposition, the criteria for differentiating homonyms. Structural-semantic, distributional and oppositional analysis, linguistic experiment were used. Criteria for differentiating word forms representing different degrees of adverbialization in the zones of the periphery and core of adverbs are established. The meanings of objectivity and adverbiality are recognized as the main criteria. The presence of part-of-speech semantics of the subject in the disputed word forms predetermines the implementation of the categories of gender, number and case, case-numerical paradigms, the system of inflections and the typical function of complement in them. The formation of adverbial semantics in nouns leads to their decategorization, loss of categories and paradigms, transformation of the morphemic structure caused by the degeneration of inflection into a suffix and expansion of the word base, as well as to the acquisition of the typical function of adverbial circumstance. It is proved that as a result of the stepwise adverbialization of the instrumental case of nouns, grammatical homonyms arise that do not break the semantic connection with the substantive lexeme; hybrids and nuclear adverbs that function as lexical and grammatical homonyms.
