Origin of warfare
1425–75; late Middle English werefare, i.e., a faring forth to war; see war 1, fare
Explanation
When two countries fight violently with each other, the conflict is called warfare. Whenever a group engages in war or violence, it can be described with the noun warfare, which is another way of saying "the act of war." Terrorists might use guerrilla warfare tactics against their enemies, and governments may resort to warfare to put down revolutions. The word war originally comes from a Germanic root, werso, which means "to perplex or confuse."
