Etymology
The compound "early-warning" is a modern military and technical term, formed by combining two native English words of Germanic origin. The concept hinges on the literal sense of "early," meaning before the usual or expected time, and "warning," meaning an alert about impending danger. Its logic is transparent: a notification (warning) provided sufficiently in advance (early) to allow for a defensive or evasive response. The term gained prominence during the Cold War era, specifically describing radar systems designed to detect incoming missiles, and has since been extended metaphorically to any system or sign that provides advance notice of a wide range of risks, from financial crises to natural disasters.
