Morphology

sluice + gate

Given knowledge of 'sluice' (a passage controlling water) and 'gate' (a barrier), the compound 'sluice gate' is directly interpretable as the gate that controls water flow. The construction is fully compositional (noun+noun technical compound) despite being domain-specific, so a B1 learner who knows the constituents will understand the meaning.

Etymology

The noun sluice gate comes from a simple image of farmers and mill workers using a sliding wooden sluice and a gate to hold back water and then open it to let the water flow where needed. That's why today it means 'a gate you open or close to control the flow of water'.
