An excuse for a fault is an attempt at partial justification; as, one alleges haste as an excuse for carelessness. Confession is a full acknowledgment of wrong, generally of a grave wrong, with or without apology or excuse. Plea ranges in sense from a prayer for favor or pardon to an attempt at full vindication. Defense, exculpation, justification, and vindication are more properly antonyms than synonyms of apology in its modern sense, and should be so given, but for their connection with its historic usage. Compare CONFESS; DEFENSE.
