Persian shows differential object marking. We argue that objects withoutthe object marker rā are pseudo-incorporated in the verbal predicate. Specifically,we argue for an existential closure operator over the vP that binds the eventvariable of the verbal predicate, and that nominals within the vP are interpretedas dependent definites with respect to the event. We show that this results in anapparent number neutrality of such nominals, and a maximality interpretation ofanaphoric uptakes typical of E-type pronouns. The semantic contribution of nominalswithin and outside of the vP is modeled in DRT. We also argue that weakdefinites in English make use of the same strategy as pseudo-incorporated nominalsin Persian, and offer an explanation why they are restricted to readings referringto institutionalized activities.
