concord
Agreement and harmony among people who work together peacefully.
Concord means agreement or harmony between people or groups. When a family reaches concord about where to go on vacation, everyone feels satisfied with the decision. When nations work together in concord, they cooperate peacefully instead of fighting.
The word suggests genuine agreement where different sides find common ground and unite in purpose. A classroom might reach concord on new rules everyone thinks are fair, or a team might work in concord when all the players understand their roles and trust each other.
The opposite of concord is discord, which means disagreement and conflict. Where concord brings people together, discord pulls them apart. When a group that was fighting finally reaches concord, it's like everyone can finally work together smoothly instead of pulling in different directions.
