SHED, (i) A small hut, shelter or outhouse, especially one with a " shed roof " or " lean-to," a roof with only one set of rafters, falling from a higher to a lower wall, like an aisle roof. " Shed " is also the term applied to a large roofed shelter open at the sides for the storage of goods, rolling-stock, locomotives, etc., on a railway or dock-wharf. According to Skeat, the word is a Kentish form of " shade," " shadow," in O. Eng. scad, sceadu, cf. Ger. Schatten; the ultimate origin is the root ska-, to cover, seen in Gr. truta, shadow, <?Kr]vi\, tent, shelter, stage, whence Eng. " scene "; the Eng. " sky " comes from a closely allied root sku, also to cover, cf. Lat. obscurus. (2) To spill, to scatter, to cast off; originally the word seems to have meant to part, to divide, a use only surviving in " watershed." The O. Eng. verb was sce&dan, in Mid. Eng. shceden, to divide, separate. " Shed " in the sense of to spill has, however, by some etymologists been taken to be a separate word from that meaning to part ; it would in that case appear to be connected with O. Fris. schedda, to shake, the root of which is found in " shudder."
