KK: /pəˈrɒksɪd/
A type of chemical compound that contains a high amount of oxygen, often used in various chemical reactions and processes.
Hydrogen peroxide is a common example of a peroxid used for disinfection.
Peroxid is formed from "per-" (meaning through or thoroughly) and "oxide" (from Greek "oxys", meaning acid or sharp, and "-ide", a suffix used in chemistry to denote a binary compound). The term refers to a compound containing two oxygen atoms, indicating a thorough or complete oxidation process.
Think of 'per-' meaning thoroughly and 'oxide' relating to oxygen — this helps you remember that peroxid refers to a compound with a thorough presence of oxygen.
