What does "anger" mean?

Anger: A strong passion or emotion of displeasure or antagonism, excited by a real or supposed injury or insult to one's self or others, or by the intent to do such injury. Anger is like A full hot horse, who being allowed his way, Self- mettle tires him. Shak. -- Anger, Indignation, Resentment, Wrath, Ire, Rage, Fury. Anger is a feeling of keen displeasure (usually with a desire to punish) for what we regard as wrong toward ourselves or others. It may be excessive or misplaced, but is not necessarily criminal. Indignation is a generous outburst of anger in view of things which are indigna, or unworthy to be done, involving what is mean, cruel, flagitious, etc., in character or conduct. Resentment is often a moody feeling, leading one to brood over his supposed personal wrongs with a deep and lasting anger. See Resentment. Wrath and ire (the last poetical) express the feelings of one who is bitterly provoked. Rage is a vehement ebullition of anger; and fury is an excess of rage, amounting almost to madness. Warmth of constitution often gives rise to anger; a high sense of honor creates indignation at crime; a man of quick sensibilities is apt to cherish resentment; the wrath and ire of men are often connected with a haughty and vindictive spirit; rage and fury are distempers of the soul to be regarded only with abhorrence.
