Morphology

questionable = question (transparent) = question + able

The adjective is a regular derivation from the verb 'question' with the productive suffix '-able', meaning 'able to be questioned' or 'open to doubt'.

Etymology

The word questionable comes from question ('an asking') and the ending -able ('able to be'). So it literally means 'able to be questioned', which is why something questionable is open to doubt or may not be honest.
