Abstract

The influence NPs can have on the aspectual behaviour of verbal expressions, witness the pair 'eat an apple in ten minutes/*for ten minutes' and 'eat apples *in ten minutes/for ten minutes, requires an analysis of how static semantic information interacts with dynamic semantic information . An interpretation of verbs and NPs is presented in which the interaction is analyzed by using an extension of dynamic logic . First, models for DL are extended by adding a domain E of events . The intuition behind this addition is that each transition which is an element of the relation denoted by a program in DL is brought about by an event from E. This makes it possible to view a change either as an object or as a transformation of a state. Second, in addition to sequential programs, parallel programs are introduced. At the level of E this corresponds to the distinction between events and sets of events. The dynamic component of a verbal expression denotes an event-type P that corresponds to a program at the level of the transition structure S. This program has particular properties in terms of which aspectual distinctions are defined. The parallel program corresponding to sets of events is partly determined by the cardinality information introduced by the determiner as part of an argument NP. At the level of E this information functions as a boolean condition expressing the result that is brought about by the set of events. Static information therefore interacts with dynamic information by providing a condition that must hold upon termination of events
