Etymology

From Middle English coveren, borrowed from Old French covrir, cueuvrir (modern French couvrir), from Late Latin coperire, from Latin cooperi? (“I cover completely”), from co- (intensive prefix) + operi? (“I close, cover”). Displaced native Middle English thecchen and bethecchen (“to cover”) (from Old English þeccan, beþeccan (“to cover”)), Middle English helen, (over)helen, (for)helen (“to cover, conceal”) (from Old English helan (“to conceal, cover, hide”)), Middle English wrien, (be)wreon (“to cover”) (from Old English (be)wr?on (“to cover”)), Middle English hodren, hothren (“to cover up”) (from Low German hudren (“to cover up”)).

According to the Oxford English Dictionary, the original sense of the verb and noun cover was “hide from view” as in its cognate covert. Except in the limited sense of “cover again,” the word recover is unrelated and is cognate with recuperate. Cognate with Spanish cubrir (“to cover”).
