IPA: /ɪnˈfɔːrsər/
KK: /ɪnˈfɔrsər/
A person who makes sure that rules or laws are followed, often using force or intimidation.
The enforcer made sure everyone followed the rules during the game.
Enforcer → It is formed from "en-" (meaning to cause to be or to put into) and "force" (from Latin "fortis", meaning strong or powerful) and the suffix "-er" (meaning a person who). The word "enforcer" refers to a person who causes strength or power to be applied, typically in the context of law or rules.
Think of someone who 'causes' ('en-') 'strength' ('force') to be applied — that's why an enforcer is a person who ensures rules are followed.
