Lexical duplicity and rebranding as variants of semantic shifts

The article is devoted the topical problem in modern linguistics - the problem of semantic changes, derivation and shifts in the borrow edlexics. Semantic changes, or shifts are regarded in the framework of linguistic modelling. The author describes the notions of semantic duplicity and rebranding on the examples from English and French as the leading European languages, included in the author’s study of lexical correspondences. The abundance of linguistic terms, denoting the sphere of semantic derivation, mentioned in the present article, shows the topical character of this linguistic problem and a multilateral approach in solving it. All the semantic changes, studied by the author, are represented as a part of the general cognitive problem of transmitting sense, or the purport of the utterance from the point of view of logic and the criterion of verity. Linguistic problems, described in the present article, are of general cognitive and general logic character.
