In Chimane, in the context of an applicative suffix on the verb, but not otherwise, the possessor of the direct object can control object agreement on the verb, rather than the direct object itself. Agreement features are person, number, and gender. Inside possessive phrases, the possessor is agrees with the possessed noun in gender (indicating constituency of the possessor and the possessed noun) and a possessive clitic can attach to the possessed noun. Possessors of subjects (other than subjects of passives) or other objects cannot control agreement on the verb.
