Resentment is a form of anger and thus the above definition of anger applies equally to it. The difference between the two is mainly one of duration and expression. Resentment is typically a smoldering, low-burning, lasting, and repressed form of anger. It results from holding on to (nursing, indulging) a perceived past injury, or from an inability to express the anger openly to and punish or hurt the perceived offender, who holds a superior position (age, authority, control, power, etc.). In either case, the anger remains unresolved and can flare up again.
