Morphology

screw + up

The verb 'screw' has a core sense of twisting/tightening and the particle 'up' often signals increase/completion, so the image of 'twisting/tightening' maps reasonably to 'contorting the face' — learners can partially infer the meaning. However this is a metaphorical extension from a mechanical sense and the exact bodily-contortion sense may not be fully predictable without exposure, so it is not fully transparent.

Etymology

Screw up may come from the simple image of twisting and crumpling something: you screw a piece of paper up into a ball and ruin it. That's why it means 'to make a mistake' or 'to ruin something'.
