Etymology

Origin of unarmed

A Middle English word dating back to 1250–1300; see origin at un- ¹, armed ²

Explanation

When someone is unarmed, they don't have any weapons. Leave your slingshot at home if you want to be officially unarmed. Sometimes the adjective unarmed has the sense of "helpless" or "defenseless," as when you hear about military troops attacking unarmed civilians. The word is constructed by adding the prefix un- ("not" ) to armed, which has meant "prepared for battle" since the 13th century, from its Latin root arma, "tools or implements of war."
