Definition of the word permeation

The word "permeation" has its roots in Latin and Middle English. The Latin word "permeare" means "to penetrate" or "to pass through", and this concept was later borrowed into Middle English as "permeaten". Over time, the spelling and meaning of the word evolved. By the 15th century, the term "permeation" referred to the act of passing or filtering through a pore or membrane. In chemistry, the term gained further significance in the 17th and 18th centuries as scientists studied the process of liquids diffusing through solids. Today, "permeation" is commonly used in fields such as materials science, biology, and medicine to describe the movement of substances through a medium or across a boundary.
