Morphology

boat + bug

The compound is compositionally interpretable—'boat' modifies 'bug' so a learner who knows both words can infer a bug associated with boats or water (or boat‑shaped). However, the precise biological sense given (a carnivorous aquatic insect with paddle‑like hind legs) is more specific than the constituents imply, so the meaning is only partially predictable without prior exposure.

Etymology

Boat bug comes from the insect's look and movement: its flat body and paddle-like back legs let it skim across the water like a tiny boat, and because it is a small bug that eats other insects, the name now means 'a carnivorous water insect'.
