Morphology

unintelligible = intelligible (transparent) = un + intelligible

The negative prefix 'un-' directly reverses the meaning of the common adjective 'intelligible', so the meaning is easily derived.

Etymology

Unintelligible starts with un- meaning 'not' and the rest, intelligible, comes from a root that means 'to understand' and shows up in words like intelligent and intelligence. So, unintelligible means 'not able to be understood', which is why we use it for speech or sound that people cannot understand.
