Abstract
NomVallex 2.5 is a valency lexicon of Czech nouns and adjectives that besides valency of particular noun and adjectival lexical units captures several valency-related syntactic phenomena, namely (i) active and passive syntax, (ii) systemic and non-systemic valency behavior, (iii) reflexivity and reciprocity, and (iv) negation. These phenomena, represented in the lexicon mostly by deverbal and deadjectival derivatives, are described here with respect to the derivational category of denominal adjectives. Though being regarded as less typical representatives of valency bearers in the non-verbal domain, denominal adjectives turned out to be involved in all of the studied syntactic phenomena. Their syntactic behavior thus can be viewed as similar to other derivational categories, especially to deverbal adjectives.
