Morphology

stay + alert

The meaning 'to remain vigilant or watchful' is directly and compositionally derived from 'stay' (to remain) + 'alert' (mentally watchful). This verb + adjective pattern is a straightforward, cross-linguistically common construction, so a B1 learner who knows both words will readily infer the MWE meaning.

Etymology

Stay alert comes from the image of a guard who must stay in one place and be alert, ready to shout 'alert' when danger comes. So, it means 'remain watchful'.
