Reflexivity represents one of the core research tasks in current linguistics. As the use of reflexives, encoding a variety of meanings, typically brings about changes in verb valency, the description of reflexivity is highly relevant - among others - also for valency oriented studies.
In this paper, we address the reflexive in Czech categorized as a derivational morpheme (e.g., zlomit 'to break something' --> zlomit se 'to break; to crack'), with the focus on valency behavior of reflexive verbs as represented in the valency lexicon of Czech verbs VALLEX. In the data component of the lexicon, reflexive verbs, i.e., verbs with reflexive lexemes, are captured in separate lexicon entries, represented by respective verb lemma(s) containing the free reflexive morpheme se or si.
In VALLEX, there are 922 lexical entries for reflexive verbs described in 1 545 lexical units represented by 1 525 verb lemmas (this number covers almost one quarter of lexical units and one third of verb lemmas in the lexicon). Refl
