smock: [OE] Smock originally denoted a woman’s undergarment, and etymologically it may be a garment one ‘creeps’ or ‘burrows’ into. For it may be related to Old English smūgan ‘creep’ and smygel ‘burrow’ and to Old Norse smjúga ‘creep into, put on a garment’. The underlying comparison seems to be between pulling on a tight undershirt over one’s head and burrowing into a narrow space. Low German smukkelen or smuggelen, the source of English smuggle [17], may come from the same source. => smuggle
