Expiation → It is formed from "ex-" (meaning out of or from) and "piare" (meaning to atone or make amends). The word "expiation" refers to the act of making amends or atoning for wrongdoing, essentially bringing oneself out of guilt.
Think of 'making amends' ('piare') to 'come out of' ('ex-') guilt — that's what expiation means.
