However, in my experience, most people are not good at defining precisely what anger is. Therefore, it is important to get the meaning of anger and related terms clear in our minds before we proceed. First of all, anger is an emotion, an inner feeling. Although there are often outward signs that sometimes accompany anger, for example, a tensed face and a raised voice, anger itself is an inner experience. This is an excellent definition.
Anger is a hostile feeling.
Synonyms for anger are fury, resentment, rage, wrath, and indignation. An angry person often feels like yelling at, shaking, or in some way getting back at another person for something the other person has done. Anger can be supported by a philosophy that one should get angry or mad in certain situations, but the anger itself is still an emotion or feeling. Anger is an upset feeling, although not all upset feelings are anger. Anger is almost always preceded by some type of injury or frustration to the individual.
