a propositional attitude event in which the speaker, or the experiencer of the pretense event, presents the proposition expressed by the complement as true in an alternative reality or mental space. Example: in Ira pretended that the guests had already left, the proposition that the guests had already left is presented as true in an alternative reality from the shared beliefs of the interlocutors (or, for that matter, Ira). There is a strong implicature that the proposition does not hold in reality (that is, the shared beliefs of the interlocutors). (Section 18.2.2)
