 Vendler thought of the Aktionarten as lexical properties of verbs. That this position is dubious was pointed out by many linguists, in particular by Dowty (1979) and Verkuyl (1993). For a simple case, consider the verb drink. If we assume that being an activity is a lexical property of this verb, then surely by combining it with the noun wine this property is preserved for the complex phrase drink wine. However, if we combine the verb drink with the noun phrase a bottle of wine we turn an activity into an accomplishment. The converse problem arises if we assume that being an accomplishment is a lexical property of  drink. This phenomenon of aspectual reinterpretation was dubbed coercion in Moens and Steedman (1988). In  Section 6.1  we will sketch a systematic solution for these types of coercion  in mereological semantics (Krifka 1989, 1992).
