Have you ever heard of a permeant in chemistry?

Yeah, I think it refers to something that can pass through membranes, right?

Root Explanation
Permeant is derived from "per-" (meaning through) and "meare" (from Latin "meare", meaning to pass or go). The word describes something that passes through or is capable of penetrating.
Memory Tip
Think of something that goes 'through' ('per-') and 'passes' ('meare') — that's why permeant means capable of passing through.
