The word "confirm" originates from Latin confirmare, combining con- (intensifying prefix meaning "thoroughly") and firmare ("to strengthen," from firmus, meaning "steady" or "strong"). The term entered Middle English via Old French confirmer, retaining its core sense of reinforcing truth or stability. Over time, it expanded to include formal validation (e.g., agreements) and religious sacraments.
