Aspectual clusters of Russian verbs

The traditional “pair” model of Russian aspect fails to distinguish among Perfectives and ignores the fact that most verbs exist in larger clusters of three or more aspectually related forms. I propose semantic parameters that account for the interaction of aspect and actionality and use them to construct a semantic map of Russian aspectual relationships. I show, using a multiply stratified sample of 283 verb clusters (including over 2000 verbs), that the composition of clusters conforms to a strict implicational hierarchy that predicts all and only the cluster types attested in Russian. The proposed model replaces aspectual “pairs” with a model that captures the more complex reality of aspectual relationships among Russian verbs and provides a hypothesis for cross-linguistic comparison.
