What term characterizes a feeling of great anger?

The term that characterizes a feeling of great anger is "irate." This word specifically denotes a high level of anger, often with an implication of being visibly upset or enraged. Understanding the nuances of this word is important, as it captures not just a mild irritation but a strong emotional response typically associated with frustration or annoyance.

In contrast, the other options convey very different emotions. Indifferent indicates a lack of interest or concern, which is the opposite of experiencing any strong feelings, including anger. Amused suggests a state of finding something funny or entertaining, which is generally antithetical to the experience of anger. Calm indicates a peaceful or composed state, which stands in stark contrast to feelings of anger. Thus, "irate" is the only term that accurately describes a significant and intense emotional response of anger.
