When you conciliate someone, you try to make them less angry and more willing to stop fighting — and you often do it by giving them something they want: more money, an apology, a seat at the table. It is a rather formal word. At home you would just say you were trying to calm someone down, or to make up. You hear it in news about governments, companies, and unions, when one side is trying to take the heat out of a fight. Though actually, it can sound a little cold, as if you are managing people's feelings rather than truly becoming friends again. Reconcile is the warmer cousin: that is when two sides really come back together. Conciliate is often one side trying to win the other over, sometimes by giving in.
