This study deals with the issue of mismatch in semantic number between the controller(singular) and PRO(plural) on partial control in English. Based on Rodrigues's (2007) proposal, this paper argues for the movement plus pro-stranding analysis, in which an associative plural morpheme pro adjoined to a DP controller has the advantage of explaining a case of mismatch in semantic number. First, this paper discusses the phenomenon of partial control and argues that it has the same properties as exhaustive control. Then it points out several problems of the Agree-based theories which refute Landau's (2007) persistent claim. It also argues that the Move-based analysis is definitely preferred to the Agree-based analysis in dealing with partial control, showing Parasitic Partial Control Effects within the adjunct presented in Witkoś & Snarska (2008). Furthermore, this paper suggests two derivation models for split control to support Move-based analysis without violating minimality. This study concludes that like the partial control, the split control is compatible with Move-based theories of control.
