IPA: /ˈfjuːdɪst/
KK: /fjuːdɪst/
A person who takes part in a long-standing argument or conflict, often involving families or groups.
The two families have been feuding for generations, and each feudist plays a role in keeping the conflict alive.
Feudist → It is formed from "feud" (from Old French *feude*, meaning a prolonged and bitter quarrel or dispute) and "-ist" (meaning a person who practices or is concerned with something). A feudist is a person involved in or characterized by a feud.
Think of a 'feud' as a long-standing dispute, and the '-ist' means a person involved in that dispute. So, a feudist is someone who is part of a feud.
