AbstractThe article is an extension of the author's series of publications on derivational paradigmatics of the Ukrainianlanguage. Derivational paradigms of nouns-names of persons according to their internal features constitutethe focus of the article. The structural and semantic characteristics of the units under study are established, andthe linguistic and extra-linguistic factors of influence on the formation of the component structure of derivationalpotential are investigated.ResumeAmong the most urgent problems to be solved in Ukrainian derivatology, there is the problem ofparadigmatic relations of language units in word formation, as represented by the derivational paradigm.This paradigm is the universal systematic way of determining the derivational potential of wordsbelonging to different parts of speech, because it is structured by sets of derivatives in paradigmaticrelations, which are directly motivated by the very same derivational word. The parameters of derivationalparadigms of nouns in the Ukrainian language depend on the derivational capacity of motivationalwords of certain lexico-semantic groups, which is conditioned by a complex of semantic, structural,functional-stylistic and pragmatic factors, with the semantic one being the determinant. The articlefocuses on paradigms of nouns-names of persons according to his / her internal characteristicsand analyzes the dependence of the derivational potentiality of these nouns on their semanticemergence. Two groups of suffixed nouns, i.e. names of persons according to their external and internalcharacteristics, are considered. These quite small groups of nouns are distinguished by the peculiaritiesof their formal grammatical and semantic representation that determine the set of specific derivationalparadigms and their parametric features. The nouns with emergent semantics always contain someadditional components in their meaning structure – semantic extensions, which have no expressionin their formal structure, and have more derivational capacity than the words with non-emergentsemantics. The parameters of a typical derivational paradigm of these nouns are determined andit is established that the semantic peculiarity of the derivational base, namely the emergence of theirsemantics, determines the derivational potential of vertex nouns to form derivatives belonging to oneof the three parts of speech: noun, adjective or verb. The derivational potential of a lexico-semanticgroup of nouns with a weak or zero emergent level, that is those without semantic extensions,is equally analysed. It is shown that they reveal a lower derivational capacity: the lexemes withnon-emergent semantics form mostly single-word derivational paradigms with a limited quantitativerepresentation and that are structured by the absence of derivatives in the adjectival and verbalzones. Their typical derivational paradigm is structured by derivatives of only one substantival zonewith modifying meanings.
