Abstract

An investigation into the behavior of sentence-final then suggests the need to distinguish between two uses:As a temporal anaphor referring back to a previously established explicit temporal referent (ETR).As a way of expressing relations between states/events, where no ETR is required.A means of making this distinction in Discourse Representation Theory (DRT) (Kamp and Reyle (forthcoming)) is proposed. This involves restricting the introduction of temporal referents into the universe of discourse to cases where certain types of temporal adverbials are present. In other cases, event or state referents but not temporal referents may be introduced. This contrasts with previous DRT accounts of temporal phenomena, which employ no such distinction
