Abstract
The article deals with specific features pertaining to the verbal categories of person, mood, (partially the voice), tense and aspect at illocutionary verbs arising from the occurence of mentioned verbs in performatively used utterances (in the basic form of the 1st person singular indicative, pres. tense imperf.). The notion of performativity is explained as a pragmatic value of an utterance, based on the accomplishment of a deed (act) denoted by the lexical meaning of a verbum dicendi while the core of the speech act performance consists of the coincidence of locution and illocution (in Austinian sense).
The essential prerequisite making the utterance suitable for performative use is seen in its temporal qualities shown through Reichenbach's tense deconstruction.
