What does permeation mean?
Permeation is the process of spreading through or passing into a material, environment, or group. In science, it can describe the movement of a liquid, gas, or other substance through a porous barrier or across the components of a material. In social and cultural contexts, it refers to the gradual diffusion of ideas, attitudes, habits, or influences through an institution or population. The word suggests a process that is often continuous and relatively diffuse rather than a single, obvious act of entry. It is related to “permeate,” the verb describing the act itself, and “permeability,” the property that makes a material able to allow passage. Permeation is useful when discussing both physical movement and the subtle spread of ideas or practices through a society.

Where does permeation come from?
Permeation was formed in the early 19th century from Latin permeare, “to pass through” or “penetrate,” with the suffix -ation added in the usual English pattern for forming nouns of process. Latin permeare combines the prefix per-, meaning “through,” with meare, “to go or pass.” Its relatives include “permeate,” “permeable,” “permeability,” and “impermeable,” all reflecting the same idea of passage through a material or barrier.
