amity (n.)

mid-15c., "friendly relations," especially between nations, from Old French amitie, earlier amistie (13c.) "friendship, affection, love, favor," from Vulgar Latin *amicitatem (nominative *amicitas) "friendship" (source also of Spanish amistad), corresponding to Latin amicitia, from amicus (adj.) "friendly," which ultimately is from amare "to love" (see Amy).
