Other forms: furies
Fury is wild, violent anger. Beyond irritation, beyond rage, and not remotely under control.
It is the strongest of the ordinary anger words, and it usually comes with an outward sign, so somebody white with fury or shaking with fury is visibly gone. It also describes forces, and the fury of a storm is a standard phrase. In classical myth the Furies were goddesses of vengeance, and they are where the word comes from. Furious is the adjective, and it has been weakened by everyday use in a way that fury has not.
