Morphology

crack + down

The verb 'crack' carries a literal sense of breaking and a metaphorical sense of applying force or punishment, and 'down' functions as a directional/intensifying particle, so a learner could partially infer a meaning related to strong action. However, the specific sense 'to take severe measures to stop or control behavior' is an idiomatic extension that is not fully predictable from the parts, making comprehension only partially transparent to a B1 learner.

Etymology

Crack down may come from the image of someone using a heavy tool to crack something down with a hard hit to make it stop. So to crack down on bad behavior means to take strong action to 'stop or control' it.
