Morphology

emergency + alert + system

The meaning is directly and transparently built from 'emergency' (urgent incident) + 'alert' (warning) + 'system' (organized set of components), so a learner who knows those words can infer it is a system that issues warnings about emergencies. This compositional pattern is common across languages, so a B1 learner would grasp the general function even if they might not know the specific U.S. institutional details.

Etymology

Emergency Alert System comes from the simple image of a system that sends an alert when there is an emergency. Imagine a loud tone cutting into every radio and TV to 'warn' people at once. That is why the phrase means a way to send emergency messages to many people quickly.
