Morphology

interior + door

The meaning 'a door inside a building' is directly and transparently derived from combining 'interior' (inside, inner) with 'door' (a barrier for entry). This compositional pattern is common cross-linguistically and follows ordinary adjective + noun semantics, so a B1 learner who knows both words would readily understand the MWE.

Etymology

Interior door names the simple image of a door that sits inside a building: the word interior points to being 'inside', so it is the door that divides rooms. Imagine a door between your bedroom and the hallway that you close to keep out noise and make the room private — that's why it means a door that separates rooms rather than one that goes 'outside'.
