THE STRATIFICATION OF MORPHONOLOGICAL TRANSFORMATIONS OF DEVERBATIVES IN THE UKRAINIAN LANGUAGE

Abstract

The article deals with the specifics of stratification approaches in the analysis of morphonological transformations of verbal derivatives. The morphonological factors in the creation of derivatives are clarified, taking into account stratification approaches. The essential approaches for the analysis of the verbal derivatives in the morphonological aspect are established. The stratification morphonological models open up the prospects for rational and economical establishment of regularities, sequence of morphonological operations, taking into account the influence of the formant on the stem in the derivational process, the specifics of the contact zone (final of the stem and initial of the formant). The classes of suffix morphemes of the Ukrainian language subjects are defined according to the context of the alternatives and nature of the contact zone. The practical part of the study also illustrates the limiting and stimulating factors in the creation of the deverbs. It is noted that taking into according the structure of the apex words in the word-formation nest, the peculiarities of derivational processes, and morphonological rules are valid for wordchange and word-formation morphonology. In the process of analyzing the morphonological structure of the Ukrainian word nests with the apex verb, it is argued that the verbal derivatives support word-formation and morphonological models and the predictable stratification of the morphonological system. The description of the morphonology of the word-formation nest (dynamic morphonology) contributes to the establishment of the morphonological rules for the creation of derivatives of different blocks within the word-formation nest of the corresponding morphonological class (nonmembered and membered stems) and morphonological type. The mechanisms affecting the structure of derivatives are identified: truncation of verbal finals, consonantal and vocalic alternations of phonemes, extension of the root or suffix morpheme, change of the accentual position of the derivative.
