Morphology

superposition = position (semi-transparent) = super + position

The physics/mathematics sense abstracts 'overlapping/placing' into 'combination of states'; the morphological parts are related but the specific technical meaning is less directly inferable for a B1 learner.

Etymology

Superposition comes from super- ('above') and position ('place'), so it literally means 'placed above'. In physics and math this image helps: different states are like layers 'stacked' or 'placed together', so they act at the same time.
