Morphology
unperceivable = perceivable (transparent) = un + perceive + able
The negating prefix 'un-' is applied to the adjective 'perceivable', giving the clear meaning 'not able to be perceived'.
Etymology
Unperceivable starts with un- meaning 'not' and the rest comes from perceive, which means 'to notice' or 'take in' with your senses, like the familiar word receive. So, unperceivable means 'not able to be noticed', which explains why it describes something impossible or very hard to sense.
