From fundamentalism (fundamentals plus -ism) plus the adjective suffix -ic. Fundamentalism emerged in early 20th-century Protestant theology and expanded to other domains.
The word often carries negative connotation in secular discourse, but it's historically rooted in the 'Fundamentals'—1920s pamphlets defending literal Bible reading against modernism.
