shop

From Middle English shoppe, schoppe, from Old English sċoppa (“shed; booth; stall; shop”), from Proto-Germanic *skupp-, *skup- (“barn, shed”), from Proto-Indo-European *skub-, *skup- (“to bend, bow, curve, vault”). Cognate with Dutch schop (“shed”), German Schuppen (“shed”), German Schober (“barn”), French échoppe (“booth, shop”) (< Germanic). The verb is denominal. The noun senses “act of shopping”, “purchased items” are backformed from the verb.
