Larson (1988): On the Double Object Construction #

This file formalizes the analysis of [Lar88]: a ditransitive verb projects a VP shell, the oblique dative send a letter to Mary is built by merging the to-phrase as the complement and the theme as the inner specifier, and the double object construction is derived from it by the operation of Passive applied within the VP, an internal merge of the indirect object above the theme. The derivations are Derivations whose movement steps are the same internal-merge step as the clausal passive, and the c-command relations of the resulting trees give the asymmetries of [BL86]: in the oblique dative the theme c-commands the goal (oblique_do_ccommands_goal), in the double object construction the indirect object c-commands the theme and not conversely (doc_io_ccommands_do, doc_do_not_ccommands_io), as the promoted object c-commands the demoted subject of a passive. Dative shift is subject to recoverability: the content of to must be recoverable from the verb's own assignment of a goal role (recoverable), which separates give and send from donate and contribute. The indirect passive Mary was sent a letter is derived by dative shift followed by passive.

Implementation notes #

The oblique dative and dative shift are the paper's second and third sections, the indirect passive its fourth, and recoverability the second part of its fifth. The head movement of the verb from the inner to the outer shell is not modelled, since the c-command facts depend only on the positions of the arguments; each derivation is paired with the planar tree it produces, on which c-command is decided. The recoverability entries record the roles the paper assigns to each verb's indirect object.

The oblique dative #

John sent a letter to Mary: the to-phrase is merged as the complement, the theme as the inner specifier, and the agent as the outer specifier, so the theme c-commands the goal, which is buried in the prepositional phrase.

    Dative shift #

    John sent Mary a letter extends the oblique dative by one step, the internal merge of the indirect object from inside the to-phrase to the edge of the inner shell, the operation of Passive within the VP. The indirect object thereby comes to c-command the theme, which gives the six asymmetries of [BL86]: anaphor binding, quantifier–pronoun binding, weak crossover, superiority, each … the other, and negative polarity licensing.

        In the double object construction the indirect object c-commands the theme.

        And the theme does not c-command the indirect object.

        Dative shift is one internal merge, of the indirect object.

        Passive #

        The ball was kicked by John is the same internal-merge step applied in the clausal domain: the object is promoted above the subject.

          Passive is one internal merge, of the object.

          Recoverability (§5.2) #

          Dative shift requires the content of to to be recoverable from the verb: both the verb and to assign a role to the indirect object, and when the verb's roles include the goal role that to contributes, to reduces to a case marker that Passive can absorb; a verb that assigns only a beneficiary role leaves to's contribution unrecoverable, and dative shift is blocked.

                        The indirect passive (§4) #

                        Mary was sent a letter promotes the indirect object to subject: dative shift followed by passive, each an internal merge leaving a trace, so the promoted indirect object c-commands the stranded theme.
