Noncompliant → It is formed from "non-" (meaning not) and "compliant" (from Latin "compliere", meaning to fulfill or complete). The word "noncompliant" means not fulfilling or adhering to rules or standards.
Think of 'not' ('non-') following the rules ('compliant') — that's why noncompliant means not following the rules.
