Root Explanation
Undersea → It is formed from "under-" (meaning beneath) and "sea" (from Old English "sǣ", meaning large body of water). The word "undersea" refers to something that is located beneath the surface of the sea.
Memory Tip
Think of being 'beneath' ('under-') the 'large body of water' ('sea') — that's what undersea means.
