Pronunciation
Forms
soir m (plural soirs)[1] Old French ser (about 980), seir (1080), soir (about 1160).[2][3][4]
Etymology
It is inherited from Old French seir, inherited from Latin sērō (“late, too late”), an adverb formed from sērus (“late”).[5][2][6][3][7] Old Occitan had both ser (about 1135), from “sērō”, and “sera” (about 1160), from a Late Latin noun “sēra” “evening” that also gave Italian sera.[2][6] Spanish tarde and Portuguese tarde and Catalan “tarda” “evening” come in the same way from Latin tardē (“slowly; late”), while classical vesper survives in vêpres.[2][6] Rey compares “sērus” with Sanskrit सायम् (sāyám, “evening”) and Old Irish “sír” “long”.[2]
Earliest recorded meaning
It is first found in the Passion de Clermont (late 10th century) as ser, the last hours of the day.[5][2]
Semantic evolution
From Old French on it was used after the name of a day and after hier and demain (her seir, 1080).[2][5] A seyr et a matin “unceasingly” (late 11th century) became le soir et le matin (1480); du soir au matin (1668) and du matin au soir (1670) once meant “very quickly”.[2] The word meant “the west” (1341) and, figuratively, old age (1552, le soir de la vie, 1635).[2][5]
In 1690 it was used of the second half of the afternoon, a sense kept in journal du soir, and also of the part of the night up to bedtime, a sense later taken by soirée.[2][5] À ce soir is recorded in 1756, Quebec French says à soir for ce soir, and in African French soir may mean the afternoon.[8][2]
