Root Explanation

Substrate → It is formed from "sub-" (meaning under) and "stratum" (from Latin, meaning layer). The word "substrate" refers to a layer that lies beneath another layer.

Memory Tip

Think of something that is 'under' ('sub-') another 'layer' ('stratum') — that's what a substrate is, a foundational layer.
