Morphology

moving + staircase

The meaning is directly compositional: 'moving' modifies 'staircase', so a learner who knows both words can infer a staircase that moves to transport people between floors. This adjective+noun composition is a common and predictable pattern in English (and in many languages there are analogous constructions or a lexicalized equivalent like 'escalator'), so the expression is immediately accessible to a B1 learner.

Etymology

Moving staircase comes from the simple image of a staircase whose moving steps go around like a belt and carry people who stand on them. So it means 'a stairway with steps that move' used to take people between floors.
