Etymology
Origin of ferocious
First recorded in 1640–50; from Latin ferōc-, stem of ferōx “savage, fierce” ( fer(us) “wild” ( see feral 1, fierce) + -ōx “having such an appearance”; akin to eye ( def. ), oculus ( def. ), -opsis ) + -ious
Explanation
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.
