Morphology

Nearctic = near + arctic (semi-transparent) = near + arctic

Formally combines 'near' + 'arctic', but the technical biogeographic meaning (covering most of North America) is domain-specific and not fully predictable from the components.

Etymology

Nearctic comes from the parts near ('close') and Arctic ('the cold north'). So as a noun it names the region of North America that lies near the Arctic and shares its typical plants and animals.
