Morphology
superfluidity = superfluid (transparent) = super + fluid + ity
The noun 'superfluidity' is transparently derived from the adjective 'superfluid' by adding the suffix '-ity'.
Etymology
Superfluidity breaks into super- meaning 'above' or 'more than', as in superhero, fluid meaning 'liquid' or 'flow', and -ity that makes a 'state'. So superfluidity is the 'state' of a liquid that behaves 'above' normal liquids by flowing with 'no friction'.
