Morphology

trimmer = trim (semi-transparent) = trim + er

Formed from 'trim' + '-er' meaning an instrument for making fine adjustments; the link is clear but the technical electronics meaning is domain-specific.

Etymology

An electronic trimmer takes its name from trim ('to adjust or fine-tune'), meaning a small part used to make tiny changes. So a trimmer capacitor is a little device you turn to get the circuit exactly right.
