Prominent possessor constructions in Santali resemble ethical datives in that the agreement morphology that indexes prominent internal possessors, may also be used to index referents such as beneficiaries and maleficiaries (amongst other roles) that are not necessarily arguments of the predicate. However, if ‘possessive’ agreement is present, and either of the core arguments (i.e. subject or object) have a possessor, then that possessor will be the controller (and not some other referent). Verbs that agree with possessors are always marked by a suffix -ta that indicates that verbal agreement has a possessor or non-core argument as its controller.
