Morphology

killer + whale

The compound is fully compositional: a B1 learner who knows 'killer' and 'whale' can infer it denotes a whale associated with killing or predatory behavior (i.e., a type of whale). Although taxonomically it is an orca (a dolphin species), the noun+noun composition directly signals a kind of whale, making the meaning transparent and cross-linguistically accessible.

Etymology

Killer whale may come from old sailors who saw these black-and-white animals hunting big whales. They called them 'whale killers' and the words whale and killer were put together as killer whale, which is why the name means a whale that hunts and can kill large animals.
