This paper investigates aspectual meanings that resultative morphemes in Mandarin Chinese contribute to interpretations of the entire predicates, and in particular the culmination readings they bring out of the originally non-culminating accomplishments. Two resultative morphemes are studied: -wán and -diào. I argue that while both morphemes give rise to culmination readings, the culmination readings are derived in different ways. I propose that -wán expresses termination, which comments on the progress of an event. The culmination readings of the telicized accomplishments by -wán are obtained indirectly. By contrast, -diào expresses culmination, commenting directly on the resulting culmination state. The proposed analysis for the two morphemes is couched in the framework defined by Krifka (1989, 1992, 1998), which models the relations between events, individuals, and times as a series of homomorphic relations between mereological part structures. Following Zucchi & White (2001), I analyze -diào in terms of a maximalization over patient, which transfers mereological properties from the individual structure to the event structure, explaining the culmination reading, and -wán a maximalization over time, which transfers mereological properties from the time structure to the event structure, explaining termination, and then transfers the mereological properties to the individual structure, explaining the culmination reading.
