Root Explanation

Superoxide → It is formed from "super-" (meaning above or beyond) and "oxide" (from Greek "oxys", meaning acid or sharp, and "-ide", a suffix used in chemistry to denote a compound). The word "superoxide" refers to a compound that contains an oxygen molecule with a higher oxidation state than typical oxides, thus indicating its elevated reactivity.

Memory Tip

Think of 'super-' meaning 'above' and 'oxide' referring to a type of oxygen compound — this helps you remember that 'superoxide' is a more reactive form of oxygen.
