Morphology

turn + off

The sense 'to repel or cause dislike' is a metaphorical extension of the literal components (turn = change, off = away/switch off) but the emotional/affective meaning is not directly deducible from simple composition. Learners might infer a loss of interest from 'turn off' by analogy with 'switch off', yet the precise sense of causing disgust or aversion typically requires prior exposure, so it is only partially transparent.

Etymology

Turn off comes from turning a switch or knob into the off position so the power stops; you physically turn the control and the machine goes quiet. So it means 'to stop a device'.
