POLYSEMY FROM THE VIEWPOINT OF COGNITIVE LINGUISTICS
The article is concerned with the determination of nature and cognitive mechanisms of lexical polysemy. In spite of the difficulties of semantic boundaries determination, the scheme of lexical mean-ings investigations presupposes emphasizing of meanings distinction as well as determination of seman-tic cores of polysemantic words. The article is aimed at giving theoretical grounds of such semantic cores of polysemantic words, called lexical prototypes. Lexical prototypes precede actualizing of all the meanings in speech. As stereotypes within the bounds of everyday thinking they make this process easier. Each lexical prototype is chosen by a communicant and functions according to the aims and conditions of a communication process.
