Aspectual classes: past and present

This paper provides an overview of some highly influential aspectual analyses of verbal predicates from the pastfew decades. First, it discusses Manfred Krifka's mereological approach in some detail. Then, it describes the central assumptions of the more recent scalar approach and some aspectual and argument realization consequences of the scalar ? non-scalar contrast in the domain of dynamic verbs. Finally, it offers a brief discussion of why the two approaches should be integrated in future investigations of aspectual phenomena.
