This paper examines the interaction between parasitic gaps and subjects. This is a multifaceted topic which previous literature has discussed in a scattered fashion. This work integrates a variety of facts which are argued to reveal that parasitic gaps and subjects interact productively, except when interrupted by anti-locality, which is a ban on certain movements that are illegally short. The paper argues 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.
