Root Explanation

Oxidant is formed from "oxid" (from Latin "oxydare", meaning to combine with oxygen) and "-ant" (a suffix used to form nouns indicating an agent). The word "oxidant" refers to a substance that causes oxidation, meaning it facilitates the combination with oxygen.

Memory Tip

Think of 'oxid' as relating to oxygen and '-ant' indicating an agent, so an oxidant is something that helps substances combine with oxygen.
