This is the noun for how easily water, gas, or other stuff can pass through a material. A sponge has high permeability: liquid goes through with almost no fight. Thick plastic has very low permeability: almost nothing gets through. You will meet the word in science, building, and medicine — soil that drinks rain, cloth that lets sweat out, the thin wall of a cell. Though actually, in ordinary talk people more often just say “it lets water through,” and keep permeability for labs, textbooks, and reports. It is not about a person being easy to talk into things; that is a different idea.
