Stopgap → It is formed from "stop" (from Old English *stoppian*, meaning to close or block) and "gap" (from Old Norse *gap*, meaning an opening or void). The word "stopgap" refers to something that temporarily fills a gap or serves as a temporary solution.
Think of something that 'closes' ('stop') an 'opening' ('gap') — that's why a stopgap is a temporary fix.
