The word "confirmation" originates from Latin confirmatio, derived from confirmare ("to strengthen, settle, establish"). The morpheme confirm combines con- (intensive prefix, "thoroughly") + firmare ("to make firm," from firmus, "strong"). The suffix -ation denotes the action or result of the verb. Over time, the term evolved in Middle English (via Old French) to signify both the act of verification and the religious rite of affirming faith.
