permeationn.

Brit.

/ˌpəːmɪˈeɪʃn/, U.S.

/ˌpərmiˈeɪʃ(ə)n/

Origin: Either (i) a borrowing from Latin. Or (ii) a borrowing from Latin, combined with an English element. Etymons: Latin permeation- , permeatio ; Latin permeāt- , permeāre , -ion suffix¹.

Etymology: Either < post-classical Latin permeation-, permeatio passage from one place to another (a1540), or independently < classical Latin permeāt-, past participial stem of permeāre permeate v. + -ion suffix¹. Compare French †perméation penetration (1641; 1611 in sense ‘(of a fluid) easy running’). Compare later permeate v.

The action of permeating something; the fact of being permeated; penetration, pervasion, diffusion.
