a strong feeling of displeasure and usually of antagonism 2 : rage
Just to be clear, we're talking about what is essentially an emotion, which one way or another is not our strong suit. I'm just as uncomfortable dealing with my own anger as I am at seeing it in others, and tend to avoid it or overlay it with at least a calm demeanor. It always seems to me, at any rate, to be something to be controlled or avoided, not indulged. The few times I've indulged there have been mixed results: that anger/betrayal thing prompted me to withdraw into a shell of self-destructive behavior for three years instead of doing the logical thing and exploring whether or not I'd actually been betrayed. I may have blown a lifetime relationship with that stunt.
more from our good friends at Merriam Webster:
mean an intense emotional state induced by displeasure. anger,
the most general term, names the reaction but in itself conveys nothing about intensity or justification or manifestation of the emotional state <tried to hide his anger
more frequent in literary contexts, may suggest greater intensity than anger,
often with an evident display of feeling <cheeks flushed dark with ire
suggests loss of self-control from violence of emotion <screaming with rage
is overmastering destructive rage that can verge on madness <in her fury
she accused us all of betrayal>. indignation
stresses righteous anger at what one considers unfair, mean, or shameful <a comment that caused general indignation
is likely to suggest a desire or intent to revenge or punish <rose in his wrath
and struck his tormentor>.
I struck a tormentor once. That worked out well. No, really. :-)
