sac m (plural sacs)[1]

Etymology

The bag is inherited from Latin saccus (“sack, bag; strainer”), borrowed from Ancient Greek σάκκος (sákkos, “coarse cloth; sack”).[2][3][4][5][6] Rey traces the Greek word, a commercial term for packing cloth, to a Semitic language, probably Phoenician (compare Biblical Hebrew שַׂק (śaq)); Bloch and Wartburg to a pre-Hellenic language of Cilicia.[3][4] In late Latin the word also meant a coarse haircloth garment.[3][7]

Cognate with Italian sacco and Spanish saco; the word also passed into Germanic: Gothic 𐍃𐌰𐌺𐌺𐌿𐍃 (sakkus), German Sack, English sack.[3][4]

Earliest recorded meaning

It first meant a coarse cloth, in the Life of Saint Alexis (about 1050), and in the first half of the 12th century the poor garment of penance (Cambridge Psalter); the container open at the top is in Wace's Roman de Rou (1160–74).[2][3]

Semantic evolution

Many phrases grew from the container: avoir la tête dans un sac “to be in complete ignorance” (Sévigné, 1675), prendre la main dans le sac “to catch red-handed” (Académie, 1798), the sack race course en sac (1842) and mettre dans le même sac “to lump together” (Zola, 1881).[2] Vider son sac, to say what is on one's mind, is found in 1596.[8] A sac was also the bag holding the papers of a lawsuit (1478).[2][3]

At the end of the 14th century it was used for the belly, whence sac à vin “drunkard” (1485).[3] In slang it has meant money (avoir le sac “to be rich”, 1844, un sac, a thousand francs, 1846, and later ten francs), and sac à puces a dog (1881).[2][1] Donner son sac à quelqu'un “to dismiss” (1808) gave sacquer.[3] Kinds of bag multiplied: sac de nuit (1599), the infantryman's pack (1824), sac de couchage (1904), sac à main (1907) and sac à dos (1957).[2]

Pronunciation

Forms

sac m (plural sacs)[1]

Etymology

The plundering is borrowed from Italian sacco, used especially in “mettere a sacco” “to put to the sack” (14th century).[3][4][5][9] “Sacco” is short for saccomanno (“plunderer”), from Middle High German sakman (“pillager, brigand”), literally “sack man”, a compound of “sak” “sack” and “man” “man”, because plunderers carried their loot off in sacks.[3][4][5] Rey notes that the first element may go back to Latin saccus, but that “saccomanno” has also been derived from a Vulgar Latin verb of Germanic origin.[3] Wiktionary instead derives the word from Old Norse saka.[1]

Earliest recorded meaning

Bloch and Wartburg find it about 1400 in the memoirs of Marshal Boucicaut, a governor of Genoa: mettre la ville à sac; the Grand Robert and the Petit Robert date it 1420, and Rey 1466–67, in metre en saq “to massacre”.[4][5][9][3]

Semantic evolution

Mettre à sac, to plunder a town thoroughly, is recorded from 1527; in the 19th century Balzac weakened it to “to turn upside down”.[3] Middle French also took saquement (1422), saquemand (1596), “pillager” and “pillage”, directly from the German word.[3][4]

Timeline

  • c. 1400 – Mettre la ville à sac, Boucicaut.[4]
  • 1422 – Sacquement “pillager”.[3]
  • 1527 – Mettre à sac.[3]
