Uncap → It is formed from "un-" (meaning not or opposite of) and "cap" (from Old French *caper*, meaning to cover or to put on). The word "uncap" means to remove a cover or lid, essentially the opposite of putting one on.
Think of 'not covering' ('un-') something that is 'covered' ('cap') — that's why uncap means to take off a cover.
