Morphology

upper + side

The meaning 'the highest or uppermost surface' is directly and compositionally derived from 'upper' (toward the top) + 'side' (surface), so a learner who knows both words can infer the MWE meaning. This is a common, literal compound-like pattern across languages and follows standard English adjective+noun composition, making it immediately understandable to B1 learners.

Etymology

Upper side names the upper or top side of something — the part you see from above, like the top of a box or the sunny face of a rock. So it is used to mean 'the highest surface' of an object.
