Misbehavior → It is formed from "mis-" (meaning wrongly or badly) and "behavior" (from Old French *comportement*, meaning conduct or manner of acting). The word "misbehavior" refers to conduct that is wrong or bad.
Think of 'mis-' meaning wrong and 'behavior' referring to how someone acts. This helps you remember that misbehavior is acting in a wrong way.
