A more thorough explanation:

Definition: Peccavi (pe-kay-vI or pe-kah-vee) is a Latin word that means "I have sinned." It is used as an acknowledgment or confession of guilt.

• After being caught cheating on the exam, the student said, "Peccavi. I know what I did was wrong."
• When confronted about stealing money from the cash register, the employee said, "Peccavi. I'm sorry for what I did."

These examples show how peccavi is used to admit wrongdoing and take responsibility for one's actions. It is a way to confess guilt and seek forgiveness.
