Morphology

blow + the + whistle

The literal meanings of 'blow' and 'whistle' (to produce sound with a whistle) give a visible metaphor of sounding an alarm, so a learner might guess it signals or calls attention to something. However, the specific sense 'to report or expose wrongdoing' is a conventionalized, culturally bound extension that is not fully predictable from the parts without prior exposure, so it is only partially transparent.

Etymology

The idiom blow the whistle comes from the image of someone literally blowing a small whistle to make people notice a problem, like a referee stopping a game or a guard sounding an alarm. So, to blow the whistle today means 'to report' or 'expose' wrong or illegal actions.
