Root Explanation

Peroxy is formed from "per-" (meaning through or thoroughly) and "oxy" (from Greek "oxys", meaning sharp or acid). The term refers to a compound containing two oxygen atoms, indicating a thorough or complete presence of oxygen.

Memory Tip

Think of 'per-' meaning thoroughly and 'oxy' relating to oxygen — this helps you remember that 'peroxy' refers to a compound with a complete presence of oxygen.
