Poetic diction and standard language: predictive aspect

The article deals with the interdiction convergence on the example of evolutionary changes in lexical semantics of poetic language. The current study contributes to the development of the methodology for studying the language evolutionary processes. The paper describes certain trends of dynamic changes and their specifics; it gives some prediction about the further lexis convergence of different types of functional styles. The findings contribute to the development of lexicography which is going to reflect not only static but also dynamic characteristics of lexical units including stylistic ones. The subjectivity of labeling poetic vocabulary in dictionaries can be partially removed through the analysis of corpus data by comparing frequency indices in different subsections, however this method is not always accurate, moreover, it doesnt effectively trace evolutionary changes. The data from the psycholinguistic experiments can help reveal the dynamics of changes. On the one hand, the results of scaling show the extent of poetry in connotative meanings; on the other hand, the open-response associative experiment allows us to calculate the archaization index of a lexeme through summing up the numerical values of certain selected parameters. The research gives obvious evidence of active archaization of some specific poetic lexemes. The findings also prove that the dynamic changes in stylistic connotation are not synchronous with the changes in the denotative layer of a lexical unit.
