(EN) Valency Dictionary of Arabic Verbs PhDr. Viktor Bielický This dissertation serves as a theoretical background for creating a valency dictionary of verbs in Modern Standard Arabic (MSA) which is primarily in the form of an electronic database. The Functional Generative Description is used as a theoretical framework for the description of verbal valency in Arabic. Chapter 1 introduces the verbal system of MSA with an emphasis on semantic relations within the system of verbal morpho- semantic patterns (verbal stems). Chapter 2 outlines the current research status of valency in Arabic including various research projects focused on creating electronic databases for Arabic verbs. Chapter 3 presents an overview of a valency theory developed within the Funtional Generative Description and it also provides a brief description of two broad coverage valency dictionaries for the Czech language - VALLEX and PDT-Vallex. Chapter 4, the core of the study, analyses semantics and the surface realization of different types of valency complemens in MSA, i.e. actants, quasi-valency and free (adverbial) complements. The final chapter, Chapter 5, describes the methodology and the structure of the valency dictionary the printed version of which is attached to the thesis. Key words: verbal valency, Modern Standard..
