permeation
UK: ˌpɜːmiˈeɪʃən | US: ˌpɜːrmiˈeɪʃən
n. the process of spreading or diffusing through a substance or space
n. the act of penetrating or passing through something
The word "permeation" derives from Latin permeare ("to pass through"), combining per- (through) and meare (to pass, go). The suffix -tion nominalizes the verb, forming a noun indicating the action or result of permeating. The root meare is also seen in words like "permeable" and "impermeable," reflecting the concept of movement or passage. Over time, "permeation" evolved to describe the gradual diffusion of substances (e.g., liquids, gases) through barriers or materials, emphasizing the idea of thorough penetration.
