Furious means extremely angry, the kind of anger that feels like it's boiling over. When you're furious, you're so angry that you might feel your face get hot, your heart pound, and your whole body tense up. The anger is so intense it takes over your thoughts and physical reactions.

You might become furious when someone breaks a promise that really mattered to you, or when you discover that a friend has been lying to you for weeks. A teacher might feel furious after catching a student cheating again. Parents sometimes become furious when their children do something dangerous, like running into the street without looking.

When someone works at a furious pace, they're working with explosive energy and speed, as if their fury has been channeled into action. A furious storm means one that's violently powerful.

Being furious is a natural human emotion, but it can make it hard to think clearly and deal with the actual problem.
