penitence

The word 'penitence' originates from the Latin verb paenitēre, meaning 'to cause to be sorry' or 'to repent'. This Latin root itself is of uncertain origin, though it may be connected to a Proto-Indo-European root implying a sense of lack or insufficiency, conceptually linked to the feeling of regret for an inadequacy or fault. The suffix -entia was added to form the noun paenitentia, denoting the state or condition of being repentant. Through Old French penitance, the term entered Middle English, where it evolved to signify the sincere feeling of remorse and the desire for atonement, a meaning it retains in modern spiritual and secular contexts.
