Morphology

trap + door

The meaning is directly compositional: 'trap' (a device to catch) + 'door' (an entry) yields a door that covers or forms a trap/opening in a floor or ceiling. This literal compound follows normal English compounding patterns and is likely inferable by a B1 learner who knows the two constituents.

Etymology

Trap door comes from the idea of a trap, a hidden opening that could 'catch' or hide things, and door, the cover in a floor. In theaters and old houses people or objects could be sent through this hidden cover to 'appear' or 'disappear', so today it means a hidden door set into a floor or ceiling.
