Nominalizations and temporal prepositions

In this paper, we deal with the semantic interaction between ung-nominalizations of different event types and temporal prepositions like wiihrend 'during', vor 'before', nach 'after', bis 'until' and seit 'since'. According to the two-level-approach to selnantics (Bierwisch 1983, Bierwisch / Lang 1989), we will argue that the meaning of ten~poral prepositions is determined on the level of semantic form (SF). When combined with an event nominal, the period in time required by the preposition has to be inferred on the level of conceptual structure (CS). Very often, the exact nature of the period in time is determined by pragmatic factors. There are, however, some important restrictions to this inference procedure which rely on the event noun's Aktionsart. In Ehrich/Rapp (2000), it was claimed that eventive ungnominals inherit the Aktionsart of their base verb. This assumption receives strong support by the data presented in this paper
