penitential

the word penitential is built upon the latin verb paenitēre, meaning 'to repent'. this verb itself is of uncertain origin, though it may be connected to a root expressing a sense of lack or insufficiency, hinting at the feeling of regret. the suffix -ent was added to form the present participle stem, creating a sense of 'repenting'. finally, the adjectival suffix -ial was appended, shifting the word to describe anything pertaining to the act or state of repentance. thus, the literal construction 'of or pertaining to repenting' evolved into the modern abstract meaning describing rituals, feelings, or writings associated with penance and contrition.
