Forms

laisser[1] Old French laissier, lessier and lesser, lazsier in the Eulalie.[2][3][1]

Etymology

It is inherited from Old French laissier, inherited from Latin laxō (“to loosen, slacken; to release; to leave”), from laxus (“loose, slack”).[4][2][5][6] Besides “to loosen, release”, the Latin verb meant “to quit, abandon, give up” and, in Late Latin, “to allow”, with an infinitive from the 5th–6th centuries.[2] It is related to lâcher.[1][2]

Old French also had a verb laier, still used in Picardy, Lorraine and Franche-Comté and behind délai and relais, Rey derives it from a Late Latin “*laggare”, an early alteration of “laxāre” after a Gaulish “*laggos” “slack”, while Wiktionary takes it from Gothic 𐌻𐌰𐌲𐌾𐌰𐌽 (lagjan, “to lay”) and Diez, cited by Littré, from Latin lēgō (“to bequeath”).[2][1][7] Wiktionary also allows some influence of Old High German lāzan (“to let”).[1]

Cognate with Romanian lăsa, Italian lasciare, Occitan laissar, Catalan deixar, Spanish dejar and Portuguese deixar; the /d/ of the Spanish and some southern forms is unexplained.[8][9]

Earliest recorded meaning

It is first found about 881 in the Séquence de sainte Eulalie, both with an infinitive, a lui nos laist venir “may he let us come to him”, and in the sense “to leave, abandon”: volt lo seule lazsier “she wants to leave the world”.[4][7]

Semantic evolution

The main senses of the Latin verb had passed into French by the end of the 12th century.[2] With an infinitive it expresses permission (laisser entrer, about 881, laisser courre, about 1050), also reflexively (se laisser mourir, about 1160).[4][2] Se laisser aller (1617) came to mean “to give way to one's inclinations” and “to neglect oneself” (1656).[2] The verb also meant “to keep in a state” (late 10th century), “to release” (1176–1181) and “to permit” (1160–1174).[4]

The sense of separation, “to go away from” a place or person, is as old (about 881), and, from it came “to leave behind” what one cannot take (about 1100), “to bequeath” (about 1100, Roland), and “to leave a mark or trace” (16th century, laisser un mauvais goût, 1690).[4][2][10] The sense “to give up, refrain from” is found from the 10th century; the classical ne pas laisser de “not to fail to” goes back to the 11th, while ne pas laisser que de was condemned by Thomas Corneille in 1687.[2][4] The noun lais “legacy” (1250) was respelled legs in the 15th century after Latin lēgātum, which cut it off from laisser.[9]
