Verbal aspect and manner of verbal action in Czech and Ukrainian language

The dissertation deals with the question of verbal aspect and manner of verbal action in Czech and Ukrainian language. The aim is to describe prefixes, which are used as means of verbal derivation and formation of aspectual pairs. The present study is divided into chapters: Introduction, Resear of verbal aspekt and Aktionsart, Verbal aspect, Manner of verbal action (Aktionsart), Competition between prefixes in the meaning of aspectual pairs formation and derivation of verbs in Czech and Ukrainian langure, Summary. There are differences in the number of verbal prefixes, which have beside derivational function also grammatical function. Czech language has sixteen of these verbal prefixes, in Ukrainian there are only seven verbal prefixes, which are used in both of these processes. This is conspicuous difference, but the results of the analysis showed, that the possibilities of applying specific prefixes are in both compared languages remarkably consistent. Many verbs of various categories of verbal action manner are derived in West and East Slavic language by the same prefixes. Consensus is also in preference of identical prefixes, which are the most commonly used during pure perfectivization (especially Czech z- and Ukrainian з-/с-).
