Morphology

water + cannon

The meaning 'a machine that shoots water at high pressure' is directly and compositionally derived from 'water' (the liquid) + 'cannon' (a device that fires projectiles): essentially a cannon that fires water. This modifier–noun combination is conceptually transparent and has clear cross-linguistic counterparts, so a B1 learner who knows both words would likely infer the MWE's meaning.

Etymology

The compound noun water cannon comes from the image of a large cannon that fires strong jets of water, like a weapon. Because these machines were used to 'push people back', the name now means a powerful device police use to disperse crowds.
