Morphology

high + alert

The phrase is directly compositional: 'high' (above normal/intense) modifies 'alert' (a state of watchfulness), so the meaning 'heightened readiness' is transparently derived from the parts. This gradable adjective + noun pattern is common in English and across languages, so a B1 learner who knows both words will readily infer the MWE meaning.

Etymology

High alert may come from old watchmen who stood in a high tower and shouted an alert when they saw danger. So, because someone high up gave a warning, high alert now means being extra 'ready' and watching for danger.
