Words related to sack
mid-13c., ransaken, "to plunder; to make a search, search thoroughly," from a Scandinavian source akin to Old Norse rannsaka "to pillage," literally "search the house" (especially legally, for stolen goods), from rann "house," from Proto-Germanic *raznan (c.f. Gothic razn, Old English ærn "house;" Old English rægn "a plank, ceiling;" see barn) + saka "to search," related to Old Norse soekja "seek" (see seek). Properly it would have evolved as *ransake; the present form perhaps was influenced by sack (v.1). Related: Ransacked; ransacking.
1738, as an anatomical term, "a diverticulum ending blindly," from French cul-de-sac, literally "bottom of a sack," from Latin culus "bottom, backside, fundament" (see tutu). For first element, see tutu; for second element, see sack (n.1). Application to a street or alley which has no outlet at one end is by 1819.
