SACK, n. [L. sagum, whence Gr. But the word is Celtic or Teutonic.]
Among our rude ancestors, a kind of cloak of a square form, worn over the shoulders and body, and fastened in from by a clasp or thorn. It was originally made of skin, afterwards of wool. In modern times, this name has been given to a woman's garment, a gown with loose plaits on the back; but no garment of this kind is now worn, and the word is in disuse. [See Varro, Strabo, Cluver, Bochart.]
SACK, v.t. To put in a sac or in bags.
SACK, v.t. [From comparing this word and sack, a bag, in several languages, it appears that they are both from one root, and that the primary sense is to strain, pull, draw; hence sack, a bag, is a tie, that which is tied or drawn together; and sack, to pillage, is to pull, to strip, that is, to take away by violence.]
To plunder or pillage, as a town or city. Rome was twice taken and sacked in the reign of one pope. This word is never, I believe, applied to the robbing of persons, or pillaging of single houses, but to the pillaging of towns and cities; and as towns are usually or often sacked, when taken by assault, the word may sometimes include the sense of taking by storm.
The Romans lay under the apprehension of seeing their city sacked by a barbarous enemy.
SACK, n. The pillage or plunder of a town or city; or the storm and plunder of a town; as the sack of Troy.
