Morphology

turn + one's + back + on

The literal meanings of 'turn' + 'one's' + 'back' + 'on' create a clear physical image (to turn your back toward someone), which gives a plausible clue that the action involves withdrawal or refusal to engage. However, the shift from a physical action to the social meaning 'deliberately ignore or abandon' is a metaphorical/pragmatic extension and not fully predictable from the parts alone, so learners need some inferencing or prior exposure.

Etymology

The idiom turn one's back on comes from the simple image of someone literally turning their back away from a person or place, so they stop facing or helping them. That's why it means 'to ignore' or 'abandon'.
