Morphology

invisible = visible (transparent) = in + vis + ible

The adjective is a standard negative formation from 'visible', and its meaning is directly interpretable as 'not visible'.

Etymology

The word invisible comes from the parts in- meaning 'not' and visible meaning 'able to be seen', the same root as vision, so it literally means 'not able to be seen', like a cloak that hides someone from sight.
