conciliate

A council is "an assembly or meeting for consultation, advice, or discussion," and it is often the task of a council to conciliate opposing views. It seems fitting, therefore, that the words "council" and "conciliate" both derive from the Latin word concilium, which means "assembly" or "council." "Conciliate" comes to us from the Latin conciliatus, the past participle of the verb "conciliare" (meaning "to assemble, unite, win over"), which in turn is from "concilium." ("Council," on the other hand, derives from the Anglo-French cunseil or "cuncile," from "concilium.") Other "concilium" descendants in English include "conciliar" ("of, relating to, or issued by a council") and the rare "conciliabule" ("a clandestine meeting especially of conspirators or rebels").
