The direct object of the verb appears either in the accusative (for total objects) or in the partitive (for partial objects). The accusative coincides with the genitive in the singular and with nominative in the plural. Accusative vs. partitive case opposition of the object used with transitive verbs creates a telicity contrast, just as in Finnish. This is a rough equivalent of the perfective vs. imperfective aspect opposition.

What other language has a telicity contrast?
