Possessors of primary objects in Nez Perce can control object agreement on the verb in the context of an additional applicative-like suffix. Possessors controlling object agreement can be external to the object noun phrase; external possessors have accusative case. Internal possessors controlling object agreement differ from these by bearing genitive and forming a constituent with the direct object as indicated by word order, for example.
In addition to object agreement, possessors of intransitive subjects can control predicate agreement. Possessive relations are not restricted to part-whole relations.
