Etymology

The word "regretful" combines "regret," derived from Old French regreter (to lament, feel sorrow), with the suffix "-ful," meaning "full of." The Old French term likely stems from a Germanic root grētan (to weep), reflecting the emotional weight of remorse. Over time, "regret" evolved to denote sorrow for past actions, and "-ful" transformed it into an adjective describing someone characterized by such feelings.
