Etymology

Origin of arms

C13: from Old French armes, from Latin arma; see _arm ²

Explanation

Arms are weapons. If a rebel group starts acquiring arms, it becomes a clear threat to its opponents. If you hear references on the news to "the arms race" or "arms exports," you know the subject is guns, bombs, bullets, and other weapons and ammunition. Any country with an army has some quantity of arms that can be used for self defense or military actions. In 1300, it was armes, "weapons of a warrior," from the Latin arma, "weapons," and also "tools of war."
