Morphology

back + out

The meaning 'to move out of a space by reversing' is directly and compositionally derived from 'back' (to move backward) + 'out' (away from the interior). This motion verb + particle pattern is common and cross-linguistically transparent, so a B1 learner who knows both words will readily understand the MWE.

Etymology

Back out creates the picture of someone stepping back and out of a room or meeting, turning away at the last minute. That's why back out means 'to decide not to do something you promised'.
