Root Explanation

Subarachnoid → It is formed from "sub-" (meaning under) and "arachnoides" (from Greek "arachnoeides", meaning spider-like). The term refers to the space under the arachnoid membrane, which is named for its spider web-like appearance.

Memory Tip

Think of something that is 'under' ('sub-') a 'spider web' ('arachnoides') — that's why subarachnoid refers to the space beneath the spider-like membrane.
