Etymology

The word "underneath" combines two Old English elements: "under" (from Proto-Germanic *under, meaning "below") and "neath" (from Old English neoþan, also meaning "below"). This doubling reinforces the sense of being beneath something. Over time, "neath" fell out of independent use but persists in this compound, emphasizing depth or concealment.
