IPA: /ɪkˈstrimɪst/
KK: /ɪkˈstrimɪst/
A person who holds extreme views or takes radical actions, especially in politics or religion.
The extremist group was known for its controversial beliefs and actions.
Extremist → It is formed from "extremus" (meaning outermost or farthest) and the suffix "-ist" (meaning one who practices or is concerned with). The word "extremist" refers to one who holds extreme views or practices, often going to the farthest limits of belief or action.
Think of someone who is at the 'outermost' ('extremus') edge of beliefs — that's why an extremist holds very strong or radical views.
