Deriving an object dislocation asymmetry in Luganda

In this paper, I document and analyze an object-dislocation asymmetry in Luganda
(Bantu: JE15) that becomes apparent only upon comparing double object left-dislo-
cation versus double object right-dislocation. If two objects are left-dislocated, the
object markers (OMs) on the verb are strictly ordered OMTHEME > OMGOAL/BEN and
the dislocated objects are ordered freely, either goal/ben > theme or theme >
goal/ben. In contrast, if two objects are right-dislocated, the objects cannot be
freely ordered — two right-dislocated objects must be ordered goal/ben > theme.
However, in double object right-dislocation, the OMs must also be ordered OMTHEME
> OMGOAL/BEN . I propose that this asymmetry can be captured if left-dislocated ob-
jects are base generated in their surface position, whereas right-dislocated objects
are derived via movement. Several predictions concerning binding and superiority
effects are borne out, providing support for the analysis.
