Etymology

It is inherited from Old French mercit, inherited from Latin mercēs (“wages, reward; price, (Late Latin) favour, mercy”), accusative “mercēdem”.[2][3][4][5][6] The Latin word meant “wages, reward, pay, interest”; in Late Latin it took the senses “price” and “favour, grace shown in sparing someone”, and Christian writers used it for kindness, pity and divine grace.[3][2][4] Rey and Littré relate it to merx (“merchandise”), the GLLF to mereō (“to earn, deserve”).[3][7][8]

Cognate with Italian mercé, Old Occitan merce, Catalan mercè, Spanish merced and Portuguese mercê.[9][7] Spanish “vuestra merced” “your grace” became the pronoun Spanish usted.[9]

Earliest recorded meaning

It is first found in the Séquence de sainte Eulalie (881), meaning “grace, mercy, pity”: the poem asks that Christ have mercit on us after death.[2][3][7]

Semantic evolution

The sense “mercy” survives in phrases no longer clearly understood: crier merci (about 1135) and demander merci (1176–1181) “to beg for mercy”, sans merci “pitiless” (1181–1190), Dieu merci “by the grace of God” (about 1100) and à la merci de “at the discretion of” (1538).[2][3][4] In courtly language it was the favour a lover won from his lady (about 1200), whence le don de merci (1462) and La Fontaine's don d'amoureuse merci.[2][3]

As a word of thanks it appears as granz merciz in the Couronnement de Louis (about 1135); Bloch and Wartburg trace it to phrases such as vostre merci “thanks to you”.[2][4] Long feminine, it became masculine (Marot, 1539) because the invariable old adjective in grand merci was taken for a masculine, grand merci passed into English as gramercy.[3][4] Merci as a polite refusal dates from 1897.[3] The verb remercier (14th century) was formed through the old verb mercier.[4]
