Derivations
Forms
fiancer[1] Old French fiancier, Picard fianchier;[2][3][4] Anglo-Norman fiancer and fiauncer.[2][3][4]
Etymology
It is formed from French fiance (“pledge, trust”) + -er, first as Old French fiancier.[3][1][5] The noun fiance, “oath of fealty” and later “trust”, is from French fier1 (“to trust”), with the suffix -ance.[3][6] The verb fier1 comes from Vulgar Latin *fīdō (“to entrust”), formed from Latin fīdus (“faithful”).[7][8]
Meyer-Lübke lists Italian fidanzare “to betroth” and Old Occitan fizansar “to promise” beside it;[8] Littré gives the Occitan form as fiansar.[9]
Earliest recorded meaning
Its first sense was “to pledge one's word, to promise on oath”: the TLFi's first record is in Chrétien de Troyes's Erec et Enide, about 1170.[3][6][5] Littré quotes a 12th-century line where the two sides jurer et fiancier (“swear and pledge”) never to start a war again.[9]
Semantic evolution
The sense “to engage oneself to marry a woman” is found in Gerbert de Montreuil's Violette (1225–1229),[3][6] and Bloch and Wartburg date the modern sense to Beaumanoir in 1283, the older sense “to make an engagement” lasting until the 15th century.[7] Froissart still used it of a captured knight pledging himself as prisoner.[9] The past participle was used as a noun, fiancée, by 1367, and the reflexive se fiancer is recorded from 1736.[3][6]
From 1833 the verb is used figuratively, “to unite harmoniously”, a literary use found in Quinet and later in Verlaine.[3][6][2]
