Синестезия интралингвистических и экстралингвистических факторов языковой эволюции

The article reviews the features of language evolution in terms of integration of those extra-special and intra linguistic factors that create cognitive dissonance in a multiethnic and multilingual society. Language functioning in the 21st century, and especially their evolution, is largely beyond the scope of the traditional interpretation of the mechanism of language evolution based on the interaction of linguistic and extra-linguistic factors. The article traces the role of synergy in the process of a possible ethnic and linguistic absorption applied to Slavic languages.
