This thesis presents an analysis of the use of the infinitive in written Czech of non-native speakers at A1-B1 levels. In the theoretical part, the category of the Czech infinitive is described in two ways. First the infinitive is discussed from a grammatical point of view.

The first part consists of a quantitative analysis of infinitive constructions, which aims to map the frequency of their use at individual levels and to compare this frequency with the target language represented by the SYN2020 and SKRIPT2012 corpora. Complementary to the first part, a qualitative analysis of a sample with 1,177 occurrences was performed, in which a total of 161 incorrect uses of the infinitive were found. These 161 occurrences were subjected to a qualitative error analysis, the aim of which is to classify and characterize specific errors in the use of the infinitive at A1-B1 levels and to determine the most common tendencies (i.e., manifestations of...
