Protestant
UK: ˈprɒtɪstənt | US: ˈprɑːtɪstənt
n. 1. A member or adherent of any Christian denomination that separated from the Roman Catholic Church during the Reformation.
n. 2. (protestant) A person who protests or objects to something.
The term "Protestant" originated in 1529 during the Diet of Speyer, where German princes and cities formally protested against the Catholic majority's decision to revoke toleration for Lutheranism. The Latin root protestari ("declare publicly, testify") combines pro- (forth) + testari (witness), reflecting the reformers' public defiance. The suffix -ant (from Latin -ans) denotes "one who does," thus labeling adherents as "those who protest." Over time, it expanded to describe all non-Catholic Western Christian traditions.
