Morphology

undetected = detected (transparent) = un + detect + ed

The adjective is formed by adding the productive negative prefix 'un-' to 'detected', producing the straightforward meaning 'not detected'.

Etymology

Undetected starts with un- meaning 'not' and comes from detect, which means 'to find', like a detective who looks for clues. So undetected describes something that was 'not found' or 'not noticed'.
