Morphology

resolver = resolve (semi-transparent) = resolve + er

Formed from 'resolve' + '-er', but the specialized electromechanical device sense (position sensor) is technical and may not be obvious to general learners.

Etymology

The word resolver comes from the Latin parts re- and solvere, which mean 'to loosen' or 'to solve'. In machines, a resolver is a device that 'finds' the exact position of a moving part, so the name fits its job of giving precise position information.
