This paper supports the claim that there are types of movement that do not leave a copy, showing that PP shift does not leave a copy. A close examination on licensing conditions of Swiping (i.e., sluicing with an inverted preposition) reveals that a complement PP is not "given" inside the VP when it undergoes PP shift. As an implication of the analysis, the Swiping data show that Gapping/Pseudo-gapping remnants undergo copy-free movement such as PP shift. The authors also raise a question as to how we should handle copy-free movement under the Copy Theory of Movement.
