Root Explanation

Interstitial → It is formed from "inter-" (meaning between) and "sistere" (meaning to stand). The word describes something that stands or exists in between spaces.

Memory Tip

Think of something that exists 'between' ('inter-') two things that 'stand' ('sistere') — that's what interstitial means.
