Morphology

undetectable = detectable (transparent) = un + detect + able

The word is formed by adding the negative prefix 'un-' to 'detectable' (detect + -able), yielding 'not able to be detected'.

Etymology

The word undetectable breaks into un- 'not', detect 'to uncover', and -able 'able to'. The root detect is the same as in detective, a person who finds hidden things, so undetectable means 'not able to be uncovered' or 'cannot be found'.
