Morphology
impermeableness = impermeable (transparent) = im + permeable + ness
The noun is formed by adding '-ness' to the adjective 'impermeable', producing the expected meaning 'the quality of being impermeable'.
Etymology
Impermeableness is made of im- meaning 'not' and permeable, from a root that means 'pass through', as in permeate. So impermeableness is the quality of 'not letting liquids pass through', like a raincoat or a dam that keeps water out.
