Pronunciation

Forms

lacs m (invariable)[1] Old French laz and las; the spelling lacs appears about 1360, in Froissart.[2][3][4]

Etymology

It is inherited from Old French laz, inherited from Latin laqueus (“noose, snare, net”).[5][6][7] The Latin word was a hunting term, later used figuratively for a trap, and Rey thinks it was probably borrowed, perhaps from Etruscan, like many Latin words with the same ending.[7] The old spelling was still found in 1636.[5] The modern spelling with ⟨c⟩ follows the related lacer and lacet.[5][2][4] Littré explains the modern form as the old stem with the ⟨s⟩ of the old forms added.[8]

Cognate with Italian laccio, Old Occitan latz, Spanish lazo and Portuguese laço.[8][4][9][1] The Spanish word is the source of lasso.[1]

Earliest recorded meaning

It first appears as laz in the Chanson de Roland (about 1100), for the laces that tied the helmet to the hood of the hauberk.[5][7]

Semantic evolution

From its first sense of a cord used to fasten something, lacs was used about 1150 for the laces of a tunic and, in 1388, for the silk cord on which the king's seal hung from his letters.[5][7] A figurative use for bonds appears in the first half of the 12th century, in the Cambridge Psalter.[5] The hunting sense, a noose or snare to catch game, is found in Marie de France about 1170, and its figurative use for a trap a few years later.[5][7]

Both the hunting sense and the figurative trap have since fallen out of use, and the word is now much less common than its diminutive lacet.[7] Lacs d'amour, an ornamental cord in the shape of a figure eight lying on its side, is recorded from 1420 and still occurs.[5][7] Bloch and Wartburg call the word only literary today.[4] The Old French word passed into English as lace in the early 13th century.[10]

Usage notes

Littré gives the pronunciation /lɑ/ and says the ⟨c⟩ is never pronounced, with the ⟨s⟩ heard only in liaison.[8] The phrase tomber dans le lac “to fail, come to nothing” is traced back to tomber dans les lacs “to fall into a trap”.[7]
