ASPECTUAL COMPOSITION: NEW EVIDENCE

have shown that the telicity feature of a clause is derived from the similar features of its constituents. These appear to be the feature of the quantification of the internal object, and of the event type of the verb (dynamic or stative). The classic approach in (Vendler 1967) suggests that the entire set of aspectual features is pre-determined for each verb in the lexicon; in more modern approaches, by contrast, the idea of compositionality constitutes a significant difference vis-à-vis the Vendlerian conception. Predication (1а) is atelic, and (1b) is telic, as is proved by the tests with durative adverbials. (1) English a. John ate [apples][–QUANT] {for three hours/*in three hours}. b. John ate [the apples] [+QUANT] {*for three hours/in three hours}. The change of telicity features seen in (1) seems unexplainable in terms of Vendler’s aspectual classes. In the compositional framework it is argued that this change takes place because of the difference between the quantificational features of the internal objects in (1a) and (1b). Nowadays there are two main theories that address this issue: the PLUG theory developed by Henk Verkuyl and the mereological approach of Manfred Krifka. These theories analyze the quantificationa
