Morphology

run + riot

The components 'run' (move quickly) and 'riot' (noisy disorder/revelry) together suggest uncontrolled or disorderly behaviour, so a learner who knows both words can likely infer the general meaning. However, the collocation 'run riot' is a conventionalized, somewhat metaphorical idiom whose exact usage and nuance are not fully predictable from the parts alone, so it is best classed as partially transparent.

Etymology

Run riot comes from a clear picture: imagine weeds that run across a garden or a crowd that moves everywhere and makes a riot. So, Run riot now means 'to behave in a wild or uncontrolled way'.
