What does fundamentalist mean?
A fundamentalist is a person who holds to a strict, literal interpretation of religious texts or doctrines, typically resisting liberalizing or modernizing readings. The word originated in early twentieth-century America among conservative Protestants who defended what they saw as the 'fundamentals' of the Christian faith, but its scope has since broadened dramatically: today it can describe hardline adherents within Christianity, Islam, Judaism, Hinduism, and other traditions, and by extension anyone who treats a secular creed — whether nationalism, Marxism, or free-market economics — with unyielding devotion. Used as an adjective, 'fundamentalist' characterizes movements, regimes, or institutions built on such rigid belief. Because the term often carries connotations of intolerance, anti-intellectualism, or extremism, it is frequently deployed pejoratively in public discourse, and careful speakers distinguish genuine description from insult. Its journey from a self-description of devout believers to a general label for dogmatic rigidity makes it a revealing case study in how words evolve with cultural conflict.
A person who adheres strictly and literally to the beliefs of a religion or, by extension, an ideology, often rejecting modern or moderate interpretations.

The word 'fundamentalist' was born in America around 1920, coined from a series of conservative Christian essays called 'The Fundamentals' — before spreading to describe hardliners of every faith and even politics.

Etymology of fundamentalist
The noun derives from 'fundamental,' which comes from Latin 'fundamentum,' meaning 'foundation' (from 'fundare,' to lay a base), via English use of the plural 'fundamentals' for core doctrines. The specific term 'fundamentalist' arose in American Protestant circles around 1920, associated with 'The Fundamentals,' a series of essays published between 1910 and 1915 defending traditional Christian doctrine against liberal theology and historical criticism. Related forms include 'fundamentalism' and the adjective 'fundamentalist'; cognates rooted in the same Latin word include 'fundamental,' 'founder,' and 'foundation.'

How fundamentalist is actually used
Though originally specific to early twentieth-century American Protestantism, the term is now applied across religions and, sometimes critically, to secular ideologies. It frequently carries negative connotations — implying rigidity, intolerance, or anti-modernism — so writers should take care to distinguish neutral description from polemical use. The adjective form is common in phrases like 'fundamentalist movement' or 'fundamentalist regime.'
