Root Explanation
Supercoil → It is formed from "super-" (meaning above or over) and "coil" (from Old French *coiler*, meaning to twist or wind). The word "supercoil" refers to a structure that is twisted or wound in a manner that is above or beyond the normal coil.
Memory Tip
Think of something that is twisted or wound 'above' ('super-') the usual way — that's what a supercoil is.
