Morphology

preselection = selection (semi-transparent) = pre + select + ion

The morphological parts are clear, but the sense refers to a specialized radio filtering process that is technical and may not be fully deducible by general learners.

Etymology

Preselection comes from pre- meaning 'before' and selection from select, meaning 'choose'. In radio use, a preselection is a first 'choosing' step before the main receiver that lets only the right frequencies through, like a small filter that keeps out other stations.
