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 It sometimes could have a positive sense in English, "appreciate, be grateful for" (1640s), but this is obsolete.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