IPA: //frɒnˈdɜːr//
KK: /fron-dur/
A person who opposes or rebels against authority, especially in a political context.
The frondeur challenged the government's decisions during the protest.
Frondeur → The word originates from French, derived from "fronde" (meaning sling) and the suffix "-eur" (indicating a person who performs an action). A frondeur is thus a person who uses a sling, metaphorically referring to someone who rebels or opposes authority.
Think of someone who 'slings' ('fronde') their discontent against authority — that's why a frondeur is a rebel.
