Morphology

imperceivable = perceivable (transparent) = im + perceive + able

The negative prefix 'im-' directly negates 'perceivable' to give 'imperceivable', following standard English derivation.

Etymology

Imperceivable breaks into im- 'not' and perceive 'to notice or take in'. So imperceivable means something you cannot notice or detect.
