Meaning

noun harmony of people's opinions or actions or characters

noun concurrence of opinion

noun a written agreement between two states or sovereigns

originFrom Middle English accorden, acorden, borrowed from Old French acorder (compare modern French accord and accorder), from Vulgar Latin *accordāre, from Latin concordāre via prefix substitution (with Latin ad-), ultimately from Proto-Indo-European *ḱḗr ~ *ḱr̥d-, and thus distantly related to English heart (via Proto-Germanic *hertô).
