Etymology

Middle English merci, mercy "mercy," from early French merci, mercit (same meaning), from Latin merces "price paid for something, wages, reward"

Word Origin

To the ancient Romans, the Latin word merces meant "price paid for something, wages, reward." The early Christians of Rome used the word in a slightly different way. For them it meant the spiritual reward one receives for doing a kindness in response to an unkindness. The word came into early French as mercit or merci with much the same meaning as was later passed on to our Modern English word mercy. But while mercy in English now has the meaning "kindness or pity shown to someone," the word merci in French has lost much of that meaning and is chiefly used today to mean "thank you."
