The Role of Grammatical Constraints in Lexical Component in Functional Generative Description

The present paper deals with selected morphological and syntactic features of Czech verbs. Working within the framework of Functional Generative Description (FGD), we demonstrate which features of lexical entries are required by the syntactic component of the description. In addition to the passive voice, traditionally described as diathesis, we briefly describe other kinds of proposed diatheses (resultative-1, resultative-2, and recipient). The constraints for their application will be present as features in the corresponding lexical entry; they will be a part of verbal paradigm in formal morphology. Regular operations within hierarchy of valency participants and their surface-syntactic positions are introduced into the grammatical component. Reciprocalization is characterized as a kind of shifting of valency complementations into the surface-syntactic position. We also specify the requirements of the verbs governing the infinitive and content clauses and point out to the interplay between the governing verb and modality of the content clause.
