Root Explanation
Noneffective → It is formed from "non-" (meaning not) and "effective" (from Latin "effectivus", meaning producing an effect). The word "noneffective" means not producing an effect or not effective.
Memory Tip
Think of 'non-' meaning not, and 'effective' meaning producing an effect — so noneffective describes something that does not produce an effect.
