Morphology

permeance = permeate (transparent) = permeate + ance

Formed by a regular derivation from the verb 'permeate' with the noun-forming suffix '-ance', denoting the capacity or state of being permeated, which is inferable from the base.

Etymology

Permeance comes from parts per- 'through' and meare 'to go', and it is the same idea you see in permeate and permeable. So, permeance is about how easily gases or water vapor can 'go through' a material.
