Morphology

under + glass

The meaning is directly built from 'under' (beneath) + 'glass' (a transparent cover), so a B1 learner who knows both words can infer that something is kept or displayed beneath a glass cover. This is a straightforward spatial/compositional pattern found across many languages, making the expression immediately comprehensible without prior exposure.

Etymology

The phrase under glass comes from the picture of an object placed under a glass case in a museum or shop. So, being under glass today means it is 'kept safe' and 'on show' for people to see.
