The study of interaction mechanism of linguistic units of different parts of speech in Russian grammar classes (based on predicativation)

The articles gives the reasons for the necessity of studying organization and operation of the mechanism of substantivization of language units in the Russian language in the theoretical course of the modern Russian language and special course „The phenomena of substantivisation and syncretism of the parts of speech, grammatical, and lexico-grammatical categories”. The paper describes the nature, attributes and levels of predicativation of words and word-forms of different speech parts, types of predicates and syncretic speech patterns manifesting different links of impersonal predicative transposition of verbs in the form of participles, functional and functional-semantic homonyms, hybrids that are in the interaction area of different parts of speech and synthesize in varying proportions distinctive features of the original word classes and semantic-syntactic category of predicates.
