Structural model of an impersonal sentence in Czech language

INTRODUCTION In modern Slavic science, the syntactic level remains one of the least studied structural levels of Slavic languages. Many current problems of Slavic syntax, which require a thorough theoretical coverage of a number of issues related both to understanding the intra-syntactic organization of monosyllabic, including impersonal, sentences in Slavic languages, and with the problem of modeling the relevant syntactic units, unfortunately, did not find a synonymous unambiguous solution in the scientific literature. As the analysis of the scientific literature on the researched problem shows, in modern linguistics sentence models are often analyzed without taking into account their functional characteristics 1 . This approach deprives syntactists of the opportunity to give an in-depth interpretation of many types of Slavic sentences, including impersonal, which are built on the same structural model, but differ in the nature of syntactic functions of components, which has been repeatedly drawn by the attention of a number of researchers. In linguoslavistics on the basis of different Slavic languages impersonal constructions have been thoroughly studied from their formal and grammatical organization (V.V. Babaytseva, L.I. Vasilevskaya, E.M. Galkina-Fedoruk, Y.V. Lokshin, G.M. Chirva, J. Bauer, F. Danesh, W. Schmilauer, etc.). The specificity of the structural parameters of impersonal sentences in Slavic languages was observed mainly within the use of lexical and grammatical means that form the grammatical center of impersonal units, identifying their syntactic labeling, correlation with other monosyllabic communicative units, the scope of different semantic and grammatical types of individual types, as well as the frequency of their use in different styles.
