Maria Flouraki: Constraining Aspectual Composition

In Modern Greek there is a rich aspectual system, which involves both morphologically expressed grammatical aspect and eventuality types, carried primarily by the meaning of the verbal predicate. Particular emphasis is paid to the interaction between grammatical aspect and eventuality types, since it is due to this interaction that the verbal predicate acquires distinct meanings. In order to explain potential changes in the meaning of the eventualities caused by the interaction with grammatical aspect, I propose a formal analysis within HPSG, using Minimal Recursion Semantics (MRS) for the semantic representations. Following the MRS architecture, I introduce a number of relations, which represent both grammatical aspect and eventuality types. The close interaction between grammatical aspect and eventuality types triggers special meanings which traditionally can be explained by inserting contextual information into the representations. In this paper, I argue against such an analysis, providing an alternative which is based on the introduction of subeventual templates formulated by Michaelis (2003) and Pustejovsky (1995). In this context, grammatical aspect combines with eventuality types and selects eventualities or subeventualities appropriate to its selection restrictions, using information that is already there in the denotation of the eventualities.
