Thinking in the right direction

We propose to analyze right-dislocation constructions in terms of clausal coordination, coupled with ellipsis. While neither rightward movement nor base-generation of backgrounded and afterthought phrases is descriptively accurate, we show that the facts follow straightforwardly on an analysis that takes the dislocated phrase to be the surface remnant of a second clause that is underlyingly parallel to the host clause and reduced by ellipsis at PF. Right-dislocated XPs are thus theoretically assimilated to sluiced wh-phrases, fragment answers, and other sentential fragments. We furthermore suggest that the two clauses in right-dislocation are syntactically related by an abstract coordinating head, making right-dislocation an instance of specifying coordination.
