Modern russian grammar

The study aims to determine the degrees of correspondence between the differential features of nouns in the instrumental case without a preposition, which manifest the peripheral stage of the original part of speech on the scale of adverbialization on the one hand, and the differential features of nuclear nouns and the differential features of nuclear substantive adverbs on the other. The authors used the methodology of oppositional analysis and indexation. As a result, the main stages of the functional transposition of non-positional forms of nouns into the semantic-grammatical category of temporal adverbs are revealed; the share of features of nuclear nouns and nuclear subjunctive adverbs in the structure of peripheral nouns such as “zimoi” is established. The results of the study can be used in further development of the problems of interaction between the semantic and grammatical in the structure of language units.
