cul-de-sac. In French cul-de-sac (from cul, “bottom or anus,” and sac, “bag”) means the bottom of the bag or sack. First used as an anatomical term, cul-de-sac was by the early 19th century a military term for the position of an army hemmed in on all sides with no chance of escape, and then came to mean “a dead-end street,” one from which there is no exit save the entrance. |
