Morphology
The term is a straightforward descriptive compound: 'ground' (i.e., glass that has been abraded or frosted) + 'glass' conveys a translucent, hazy surface. The radiological sense is a direct visual metaphor — a lung area that looks like frosted/ground glass — so a B1 learner who knows the constituents can reasonably infer the intended meaning.
Etymology
Ground glass in medicine is a simple comparison: doctors say a lung area looks like 'ground' or 'frosted' glass because you can still see shapes but not clear detail. That's why a 'ground-glass' spot on a scan means a light, hazy area where blood vessels or airways are still partly visible.
