arms-control

The term is a modern compound noun formed in the 20th century, directly combining two established English words to address a specific geopolitical concept. The first element, "arms," derives from the Latin arma, which originally meant tools or equipment but narrowed in meaning to specifically denote weapons of war. The second element, "control," has a journey from Latin through French, originating from the idea of checking accounts against a duplicate register (contra rotulum). Literally, "arms-control" signifies the regulation or restraint imposed upon weapons. This compound logically encapsulates the core objective of international diplomacy aimed at limiting military arsenals to promote stability and security.
