Possessor raising and structural variations within the vP domain

In this paper, we analyze external possessors in Brazilian Portuguese, showing that those realizing Nominative-Case (Nominative-possessors) are not syntactically uniform, varying derivationally. These variations are related to the vP internal structure. In agentive argument structures, Nominative-possessors are licensed in obligatory control configurations. Non-agentive argument structures give rise to raising configurations. In turn, raising configurations are not syntactically uniform either. Unaccusative vPs, differently from inchoative ones, contain a dative position at the vP edge. This position is used as an intermediate landing site for the raised Nominative-possessor. Importantly, a copy of a possessor in this intermediate position alters information structure at LF, having three interpretative effects: (a) affectedness: the possessor is interpreted as being affected by the denoted event, (b) presupposition of existence: the possessor must be an existent entity, and (b) contextual confinement: the possessor-possessum is interpreted as an integral part-whole at the event time.
