If you’re mad about something and you’re not going to take it anymore, you’re feeling anger, a strong emotion you experience when you think someone has done you wrong. If you want to scream and kick, you’re feeling anger.
Anger is a powerful emotion that people feel from time to time when someone or something frustrates or annoys them. One of the roots of anger is the Greek word ankhone for "a strangling," which is a perfect description of the way anger actually feels. Indeed, anger can make you feel like strangling someone. Don’t do it! If you’re feeling a lot of anger, it’s good to take a nice, deep breath.
