Parasitic Gaps licensed by elided syntactic structure

This study provides an argument for syntactic approaches to sluicing. We base our study on the novel observation that Parasitic Gaps (PG) are licensed in sluicing contexts. We show that, in order for PGs to be licensed in sluicing contexts, overt wh-movement must occur, leaving a real gap in the ellipsis site. Therefore, the ellipsis site has the full-fledged syntactic structure that licenses PGs.
