CORRELATION OF NORTH AMERICAN ENGLISH AND BRITISH ENGLISH DIVERGENCIES IN LEXIS

The article focuses on the description of a special type of relationship that arises between lexical units within the corpus of English words in the framework of the sociolinguistic approach. Various ways of correlation between North American and British usages emerge in present-day English due to the action of two processes of the language development favoured by a set of historical, linguistic and sociolinguistic factors: divergence and convergence. The paper describes the most frequent forms of lexical correlation between North American English usage and British English usage. The research states that the semantic structure of the lexical unit or its register of usage can undergo changes under influences of the other variety. The lexemes, common to both national varieties with partial coincidence of the semantic structure and, sometimes, with shifts in the register of usage, are more affected by the process of convergence. The part of the English lexis less affected by convergent processes comprises common lexemes with the split in the semantic structure, the components of which are different or antonymic. The part of the present-day English lexis likely to be involved in the process of internal borrowing mostly includes lexemes specific to US English or British English with, or without lexical equivalents in the other variety. A special kind of correlation between lexical units of common origin can bring about usages functionally confined only to one variety. The functional predominance can contribute to the formation of different chains of synonyms actualized in each of the varieties. When lexemes have lexical equivalents specific to one of the national varieties of English, the so-called ''pseudo-synonymous relations” within the English lexical system can arise
