The intricacies of parasitic gaps have long enriched research on the syntax of movement. However, the interaction between parasitic gaps and subjects is a point of contention. I integrate a variety of facts which I argue reveal that parasitic gaps and subjects interact productively, except when interrupted by anti-locality—a ban on certain movements that are illegally short. I argue that such anti-locality predicts when parasitic gaps in subject position are allowed, when subject movement licenses parasitic gaps, and has implications for the
distribution of subject A-bar movement in general.
