Root Explanation

Nontoxic → It is formed from "non-" (meaning not) and "toxic" (from Latin "toxicum", meaning poison). The word "nontoxic" means not poisonous or harmful.

Memory Tip

Think of 'non-' meaning not, and 'toxic' referring to poison — so nontoxic describes something that is not harmful.
