Morphology

water + bug

The compound 'water bug' is directly compositional: it denotes a 'bug' associated with 'water', so a learner who knows 'water' and 'bug' can infer an aquatic insect. This noun+noun modification pattern is common cross-linguistically and follows standard English compounding, making the meaning immediately accessible to a B1 learner.

Etymology

The noun water bug may come from people finding small, light-brown cockroaches in wet places like sinks and bathrooms. Because the bug was often near water, people started to call it a water bug, so today the word usually means a small household 'pest'.
