scillation within the Czech Verbal Conjugation

The Czech conjugaion is typical of relative instability of particular conjugation paradigma. The aim of this thesis is to examine a systematic transitiv of verbs of one class to another class on the one hand and to examine fluctuation of chosen verbs between different patterns, to determine topical forms of these transitions and fluctuation and finally to determine the direction of this transitiv, i. e. identificate more frequently used paradigma for each transitiv and fluctuation on the other hand. De facto it is the eximinaton of stability of verbal conjugation, with the aim to identify stronger or more dominant paradigma. A typice example of the transitiv is the migration of verbs from first class (mazat) to fifth class (dělat), a typice example of fluctuation is the second class, in which individual verbs tend to fluctuate between different patterns. Neither the fluctuation nor the transitiv do not happen at the same level in all morphological forms: the aim of this thesis is to identify these forms and determine the level and frequency of fluctuations and transitions in the contemporary usage from the corpus data (ČNK) and data obtained from questionnaires. This work is dividend into a theoretical part and a practical part. In the theoretical part we discuss verbal categories and classification of verbs based od them. Besides the classical Czech systém, we describe also one-stem systém (Townsend 2000, section 2.2), then we describe individual classes, patterns and also transitions and fluctuations esistin in the Czech verbal systém. The practical part is dedicated to verification of described tendencies. We proceed along two lines: on the one hand we use data from ČNK and on the other hand, (led by an effort to reach even spoken, not only written languages, in which the corpus SYN is based), the author made a questionnaire to which 85 people responded. The results of both examinations overlap
