Ivasiuk O. Derivational space of a polysemantic lexeme (on the material of verbs of physical perception in the Russian language)

Object – polysemantic verbs of physical perception of the modern Russian language and derivatives from them components of word-families; aim – to prove that the word-family of a polysemantic word is incomplete, it is the collection of word-families formed by lexico-semantic variants of the original lexeme-generative; methods – descriptive, systemic classification (involving analysis of vocabulary definitions, distributive analysis, component analysis, word-formation analysis, morpheme analysis), comparative-historical (involving etymological analysis), comparative, lexicographic, method of continuous selection; novelty – for the first time in Ukrainian Russian Studies: a research lacuna has been found in the description of word-families at the level of derivational space; conducted the research of the derivational space of polysemantic verbs of physical perception, taking into account the mutual projection of their epidigmatic and word-building word families; the processes that cause the formation of word-families of a special type – discrete word-family lexemes have been identified (regular divergent and possible convergent ones); a new principle of structuring word-family with polysemantic top-word is established, according to which such a word-family is considered as a set of relatively autonomous word-families, the top-words of which are the lexico-semantic variants of a polysemantic lexeme; proved that the word-forming potential of lexico-semantic variant is its specific feature; determines the place of derivatives in the structure of divergent word-families and the semantic range of derivatives, which allows to precise their vocabulary definitions and to model the dictionary entries; the use of concepts and terms «divergent word-family of a lexeme», «word-family of a sememe», «convergent word-family of a lexeme» are substantiated; the concept of derivational description of the language was further developed; results – the idea of structural complex units of word formation expands, the general theory of word-families in derivatology is supplemented, further study of divergent and convergent processes in word-families of verbs of other semantics and words of other parts of speech is stimulated; the processed factual material can be useful in lexicographic practice and be used in further derivatological research of polysemantic words, research materials can be involved in teaching disciplines «Derivatology» and «Semantics», special courses, in the development of textbooks; field – philology.
