regretful

the word 'regretful' is a relatively modern english formation, built upon the older noun and verb 'regret'. the core element 'regret' entered english from old french 'regreter', which itself has debated origins but is likely of germanic stock, related to old norse 'gráta' (to weep). the suffix '-ful' is a native english element from old english, used to create adjectives meaning 'characterized by' or 'full of'. therefore, 'regretful' literally means 'full of regret', directly and transparently conveying its modern sense of feeling sorrow or remorse for past actions or events.
