Morphology

clamp + down + on

The literal parts ('clamp' = press/fix, 'down' = downward, 'on' = targeting) suggest physically pressing something, which maps metaphorically onto restricting or suppressing an activity. The enforcement sense ('take strict action to stop') is a figurative extension that is partially guessable but not fully predictable for a B1 learner without prior exposure.

Etymology

Clamp down on comes from the image of a clamp, a tool that is pressed down to hold something tight and stop it moving. So it now means taking strong action to 'stop' or 'reduce' something unwanted or illegal.
