Typology of Ukrainian Verb Stems: Word-Forming and Morphonological Aspects

The description of word-forming morphology of deverbatives of the modern Ukrainian language in view of its functional character, dynamic processes in the language, shifts that have taken place in its corpus in recent times, provides good grounds for determining new classification principles of morphological analysis of deverbatives. The article identifies morphonological types of basic verbs of word-forming units in the Ukrainian language. The word-forming units play a dominant role in the systematization of Ukrainian word-formation, as it clearly traces the patterns of the internal mechanism, which is characterized by hierarchical connections between other complex units of the word-formation system (word-forming pairs, chains, series and word-forming paradigms). Reconstruction of the basic verbs of word-forming units makes it possible to correctly determine the direction of word-forming motivation, morphonological type and to establish a morphonological model. Their properties are clarified by the nature of the basic verb stem, morphonological transformations into morphonologically marked derivatives at different degrees of derivation. The spectrum of morphonological types of basic verbs of word-forming units in the Ukrainian language covers word-forming units of morphonological types of indivisible and divisible basic verbs of word-forming units. With indivisible basic verbs there are 5 morphological classes, with divisible basic verbs – 7.
