Excuse. In jurisprudence, an excuse or justification is a defense to criminal charges that is distinct from an exculpation. Exculpation is related concept which reduces or extinguishes a person's culpability and therefore a person's liability to pay compensation to the victim of a tort in the civil law.
Our explanations can give a matter-of-fact account of what happened. Our goal with an explanation is to advise or update the other person about a particular action, event, or situation. On the other hand, the motivation behind an excuse is to convince someone that we are justified in our action or lack of action. Excuses provide the back story for why something happened. While providing an excuse, we often defend our position. We may apologize for not meeting expectations or commitments. Sometimes we plead for forgiveness so that we can resume the relationship without guilt.
