Morphology

wise + up

The core sense 'become wise' is derivable from combining 'wise' (having good judgment) with 'up' functioning as a resultative particle indicating a change of state, so learners who know both words can often infer the basic idea of becoming informed. However, the idiomatic nuance (colloquial sense of 'get wise to' or 'stop being naive') and phrasal-verb behavior mean the exact meaning and usage are not fully predictable from the parts, so it is only partially transparent.

Etymology

The phrasal verb wise up may come from the image of someone becoming more wise and turning their understanding up, like a light switching on; when you wise up you suddenly see the true facts and stop being fooled, so it means 'to become aware of the true facts'.
