Root Explanation

Interfacial → It is formed from "inter-" (meaning between) and "facies" (meaning face or surface). The word "interfacial" refers to something that exists or occurs between two surfaces or interfaces.

Memory Tip

Think of something that exists 'between' ('inter-') two 'surfaces' ('facies') — that's what interfacial means.
