Synonyms & Antonyms

Root Explanation

Nonionic → It is formed from "non-" (meaning not) and "ionic" (from Greek "ion", meaning to go or to move, and the suffix "-ic", meaning pertaining to). The word "nonionic" describes something that does not pertain to ions or does not have an ionic charge.

Memory Tip

Think of 'non-' meaning 'not' and 'ionic' relating to 'movement' or 'ions' — so nonionic means something that does not involve ions.
