Penitence is a noun that refers to the act or feeling of being sorry for something done wrong, and showing regret or remorse. It can also refer to the practice of self-denial or self-discipline as a means of repentance for one's sins or misdeeds. Penitence is often associated with religious practices such as prayer, fasting, or other forms of atonement that are meant to make amends for wrongdoings and seek forgiveness from God or others.
