Morphology

depth + charge

The noun–noun compound is fully compositional: 'depth' (how deep) modifies 'charge' (an explosive), so a learner who knows both words can infer an explosive designed to detonate at a certain depth, typically underwater. This literal combinatory logic is common cross-linguistically and follows normal English compound formation, making the meaning accessible to a B1 learner.

Etymology

The noun depth charge comes from the simple image of an explosive charge that is set to explode at a chosen depth under the water. Ships dropped these charges to hit submarines, so the name now means 'a bomb that explodes at a specific depth underwater'.
