Morphology

invalidity = invalid (transparent) = in + valid + ity

This is a standard noun formation from the adjective 'invalid' meaning the state or quality of being invalid.

Etymology

The word invalidity comes from the parts in- meaning 'not' and valid meaning 'strong' or 'good'. So invalidity is the state of being 'not valid' – not strong or sound, which is why we use it for a wrong or illogical idea or argument.
