IPA: /ˈskɔːf.lɔː/
KK: /ˈskɔfˌlɔ/
A person who regularly breaks the law or ignores legal rules, often showing disrespect for authority.
The scofflaw parked his car in a no-parking zone and ignored the ticket.
Scofflaw is a blend of "scoff" (from Middle English *scoffen*, meaning to mock or deride) and "law" (from Old English *lagu*, meaning a rule or regulation). The term describes a person who scoffs at or disregards the law.
Think of someone who 'mocks' ('scoff') the 'rules' ('law') — that's why a scofflaw is someone who disobeys the law.
