Calculation of stages of finite verbs modulation in the Russian language

The problem of stepwise transposition of verbs into the category of parenthetical-modal units is considered in the paper. The research relevance is stipulated by insufficient knowledge of stepwise mechanisms of words and word forms transposition into other parts of speech and categories. The main purpose of the research is to calculate the stages and the limit of modulation for different groups of verbal units. General scientific, general linguistic and special methods (comparison, generalization; descriptive method, opposition, distribution and transformation analysis; linguistic experiment) were used as tools. The study of verb modulation stages has enables revealing the dynamics of corresponding fragments of the language system; use in the process of linguistic evolution of different ways of enhancing part of speech models, primarily due to their own, internal resources - “splitting” words and formation of new language units on the basis of a complex or individual word forms by means of interjectivation, partitioning, conjunctionalization, modulation, etc. It is established that the verbs belonging to different lexical groups are exposed to unequal modulation degree; finite verbs go through two to five stages of transposition until they are included into the category of parenthetical-modal units. The facts of a purely functional modulation of word forms occurring within the source verb lexemes, as well as their functional-and-semantic transposition into modal utterance components associated with the formation of lexical-and-grammatical homonyms are revealed. The results of the work can be used to create a transpositional grammar of the Russian language.
