Root Explanation

Subterranean → It is formed from "sub-" (meaning under) and "terra" (meaning earth). The word "subterranean" refers to something that exists or occurs under the earth's surface.

Memory Tip

Think of something that is 'under' ('sub-') the 'earth' ('terra') — that's why subterranean means below the surface.
