The noun comity means a state of civility or courtesy between people, organizations, and nations. It's a hoped-for mutual respect and friendliness, although too infrequently the case in politics and business. Comity is one of those rare words that has retained its original meaning through the ages. The Latin adjective cÅmis, courteous, friendly, developed into the noun cÅmitÄtem, meaning courtesy or friendliness and ultimately into English comity in the 16th century.
