KK: /ˈlɔːmən/
A person who is responsible for enforcing the law, such as a sheriff or a marshal.
The lawman arrived just in time to stop the robbery.
Lawman → The word is formed from "law" (from Old English *lagu*, meaning a rule or regulation) and "man" (from Old English *mann*, meaning a person). A lawman is a person who enforces or upholds the law.
Think of a 'person' ('man') who is associated with 'rules' ('law') — that's why a lawman is someone who enforces the law.
