Reconciliation means restoring friendship or harmony after a disagreement, conflict, or period of separation. When two friends have a serious fight and then work through their hurt feelings to become friends again, that process is reconciliation. The word involves genuinely repairing the relationship so both people can trust and care about each other again, going beyond simply ending the argument.

Reconciliation takes effort from both sides. After a conflict between siblings, reconciliation might involve honest conversations where each person explains their feelings, offers apologies, and agrees to treat each other better. It means acknowledging what went wrong and choosing to move forward together, rather than pretending the problem never happened.

The word appears in many contexts. Countries that fought wars sometimes go through reconciliation, working to build peaceful relationships for the future. In accounting, reconciling your checkbook means comparing two records to make sure they match and fixing any differences. In all these uses, reconciliation involves bringing things back into agreement or harmony after they've been out of sync. The goal is to restore something that was broken or divided.
