resentment (n.)

c. 1600, "feel pain or distress" (a sense now obsolete); 1620s, "take (something) ill, consider as an injury or affront; be in some degree angry or provoked at," from French ressentir "feel pain, regret," from Old French resentir "feel again, feel in turn" (13c.), from re-, here perhaps an intensive prefix (see re-), + sentir "to feel," from Latin sentire "to feel, think" (see sense (n.)).

It sometimes could have a positive sense in English, "appreciate, be grateful for" (1640s), but this is obsolete. Related: Resented; resenting.

1943 in the psychological sense, "state arising from suppressed feelings of envy and hatred that cannot be acted upon," a word from Nietzsche, from German ressentiment, from French ressentiment (see resentment). The French word also was borrowed as obsolete English resentiment (16c.) "feeling or sense (of something); state of being deeply affected by (something)."
