Forms

lors[1] Old French lur (about 1100), lores (1119) and lors (about 1135).[2][3]

Etymology

It is inherited from Old French lores, inherited from Late Latin illā hōrā (“at that hour”), an ablative of time made of illa (“that”) and hōra (“hour”) (compare heure);[3][4][5][1][6] its development parallels that of or “now”.[4] The diphthong /ao/ passed through /au/ to /o/; the final ⟨e⟩ was lost because the word is unstressed, and an adverbial ⟨s⟩ was added.[3] Littré instead took it from Old French l'ore “the hour”.[7]

Earliest recorded meaning

The Chanson de Roland (about 1100) has lur “then, at that moment”.[2][3]

Semantic evolution

In the 17th century lors used alone almost went out of use in favour of alors, a compound found from 1250 but rare until the 15th century.[3][4] It survives in fixed phrases: the preposition lors de (1599), which Vaugelas thought inelegant; the adverbs dès lors (1225–1230, Guillaume de Lorris; causal from 1798), pour lors (14th century, “in that case” in La Bruyère, 1688) and depuis lors (1677); and the conjunctions dès lors que (Chrétien de Troyes, 1176–1181), lors que (about 1200) and lors même que (Fléchier, 1675).[2][3][8]

From lors que came lorsque (1454), long written separately; its /s/ came to be pronounced only late (lorke in 1632).[3][4]
