Morphology

back + door

The constituent meanings 'back' (rear) + 'door' (entrance) directly suggest a rear or less-visible entrance, and this physical image readily extends to the idea of an unofficial or secret route, so learners who know the words can often infer the basic sense. However, the use as an abstract method for bypassing rules is a metaphorical extension rather than a strictly compositional meaning, so it may not be fully predictable to a B1 learner without some exposure.

Etymology

Back door is the real door at the rear of a building that people use to come and go quietly or privately. That's why it means a 'secondary or private entrance'.
