Stripping (= bare argument ellipsis) is an ellipsis mechanism that elides everything from a clause except one constituent. It occurs exclusively in the non-initial conjuncts of coordinate structures. One prominent analysis of stripping sees it as a particular manifestation of the gapping mechanism, the difference between stripping and gapping lies merely with the number of remnants left behind by ellipsis: gapping leaves two (and sometimes more) constituents behind, whereas stripping leaves just one. Stripping occurs in many languages and is a frequent occurrence in colloquial conversation. As with many other ellipsis mechanisms, stripping challenges theories of syntax in part because the elided material often fails to qualify as a constituent in a straightforward manner.
