From change to value difference in degree achievements

Degree achievements and directed motion verbs are standardly taken to describe events in which an individual undergoes change over time. The spatial uses of these verbs, giving rise to what are known as their extent readings, indicate that a temporal change based semantics is not general enough to capture their be- havior. In this paper, we introduce a further range of facts t hat argues for a fully general analysis of the meaning of degree achievements and directed motion verbs in terms of value difference rather than temporal change. These verbs are uniformly analyzed as intensional verbs that take functional arguments and encode a differ- ence in the value of this argument over a contextually given ordered domain. This analysis accounts naturally for their interaction with a ra nge of adverbial modifiers.
