Morphology

Kuiper + belt

Because 'Kuiper' is a proper name with no lexical meaning for learners and 'belt' only gives a vague idea of a band or region, a B1 learner who knows the constituents would not be able to infer the specific astronomical sense (a region beyond Neptune containing icy bodies). The term is a named scientific concept whose full meaning is not compositional or predictable from its parts, so it is not transparently derivable.

Etymology

Kuiper belt is named after the astronomer Gerard Kuiper, and the word belt gives the image of a wide 'ring' of many small, icy bodies beyond Neptune, so the name means that distant region of the Solar System.
