Morphology

corn + earworm

The phrase literally combines 'corn' (maize) with the notion of an 'ear' + 'worm', so a learner who knows 'corn', 'ear' and 'worm' can infer it denotes a worm/larva that attacks the ear of the corn. This direct noun‑noun compositional pattern is common and cross‑linguistically plausible, making the sense readily derivable without prior exposure.

Etymology

Corn earworm is named for a simple image: a small worm that eats the ear of corn, the part with the kernels. Because these caterpillars eat and damage the ears, the name now means a crop 'pest' that attacks corn and other plants.
