Permeation, noun
Permeation refers to the process by which a substance or element penetrates or spreads throughout another material, medium, or space. It is the act of permeating or passing through something, usually involving the movement of molecules or particles from one side to the other.
In a physical or chemical sense, permeation is often used to describe the capacity of a substance to diffuse or flow through another substance, such as when a gas permeates into a solid or liquid. It is a phenomenon that occurs due to concentration differences or pressure gradients, with particles naturally moving from areas of higher concentration or pressure to those of lower concentration or pressure.
In the context of biological or physiological systems, permeation is commonly associated with the movement of substances through membranes or tissues. This natural process allows for the exchange of various molecules, ions, or nutrients between cells and surrounding environments.
Permeation can also be used in a broader sense to describe the gradual spread or influence of an idea, belief, or concept. In this context, it refers to the gradual permeation of ideas or ideologies throughout a society or culture, often leading to social changes or reforms.
Overall, permeation involves the act of substances or ideas progressively spreading, diffusing, or passing through a medium or space, whether it be physical, chemical, or metaphorical in nature.

The word "permeation" is derived from the Latin word "permeatio", which comes from the verb "permeare", meaning "to pass through" or "to penetrate". "Permeare" is a combination of the preposition "per", meaning "through", and the verb "meare", meaning "to go" or "to pass". Thus, the Latin root implies the action of something passing or penetrating through a substance or material. This term has been adopted in English to refer to the process of something penetrating or spreading through another substance.
