The oldest texts write mercit, the Passion mercet, and merci appears in the 10th century.[3][4]
Etymology
It is inherited from Latin mercēs (“wages, reward”), through its accusative.[1][3][5][6] The Latin noun is formed from merx (“merchandise”).[7][1] In popular Latin it took the sense of price, whence favour, found in Merovingian Latin, and then the grace granted in sparing someone.[5] Medieval Latin used it for goodwill and pity, a ruler's grace and his free discretion,[8] and Christian writers for heavenly grace.[4]
Its Romance cognates include Italian mercè and Spanish merced.[5][9] Gamillscheg traces the phrases meaning “by the grace of God” to an old use of the ablative as a sentence adverb with the person in the oblique case.[10]
Earliest recorded meaning
The first record is mercit in the Sequence of Saint Eulalia, which the TLFi dates to 881 and the OGR and Tobler–Lommatzsch to the 9th century or about 900, in the sense of grace, mercy and pity.[6][11]
Semantic evolution
From the start the word meant the grace of sparing someone, and Old French built set phrases on it: crïer merci “to beg for mercy” about 1135, sanz merci “without pity” in Chrétien's Perceval, and estre en la merci d'aucun “to be at someone's discretion” in Erec et Enide.[6] In Chrétien it is the pardon granted at the end of a fight, and an interjection for begging it.[12] From about 1200 it was also the favour a lover hopes for from his lady.[6][3]
Phrases such as vostre merci “by your grace” turned it into a formula of thanks, whence merci “thanks” and the verb for thanking,[9] and Bloch and Wartburg date its use as a term of politeness to the 14th century.[5] granz merciz already thanks someone about 1135.[6] Old French also used the word for a fine set at the lord's discretion and for a kind of due,[3][13] and Spanish vuestra merced, the same courtesy formula, gave the pronoun Spanish usted.[9]

Anglo-Norman
The AND first cites the word from the beginning of the 13th century and lists the spellings marci, merchi, mercie, mercit and mercy.[2] Insular use was strongest in law: beside mercy and thanks the AND records the amercement, phrases for putting oneself at mercy and for incurring an amercement, and Dieu merci “thank God”.[2] Middle English merci came from Old French,[18] and Etymonline dates English mercy from the late 12th century.[19]
