The adjective ferocious means more than merely angry or active. Picture the wildest, most savage animal you can imagine — it's a ferocious beast.

Although we most often think of the word ferocious as referring to wild animals, it can also be used to describe anything characterized by an extremely high level of energy or even violence. For example, you might endure ferocious winds during a hurricane and fans at a soccer match often display a ferocious devotion to their team.
