Morphology
undetectably = undetectable (transparent) = un + detect + able + ly
The adverb is a straightforward -ly derivative of 'undetectable', whose meaning ('not able to be detected') is directly built from 'detect' + '-able' with negation 'un-'.
Etymology
Undetectably breaks into parts: un- 'not', detect, the same root as in detective, meaning 'to uncover or find', plus -able 'can be' and -ly 'in a way'. So undetectably means 'in a way that cannot be uncovered or noticed'.
