Pronunciation

  • /ɪkˈstɹiːmɪst/, /ɛkˈstɹiːmɪst/[1]

Etymology

It is formed from English extreme + -ist.[2][3][4][5] The Shorter Oxford takes it as formed like extremism, with the suffix;[6] the OED notes that extremism is recorded later,[2] and compares French extrémiste, recorded only from 1915 as an adjective and 1917 as a noun.[2] Extreme is from Old French extreme, from Latin extrēmus (“outermost, utmost, last”), the superlative of exterus (“outward”), the source of exterior.[3][2]

Earliest recorded meaning

A person who tends to go to the extreme: 1806, in B. Moseley's Commentary on Lues Bovilla.[2] Etymonline dates the noun, a supporter of extreme doctrines, to 1840,[3] and the first edition of the OED had it from 1846.[7]

Semantic evolution

From the start the word described a person disposed to go to extremes, and especially a member of a party advocating extreme measures.[2][7] Its main use is political or religious: one who holds extreme views or advocates illegal or violent action.[2][8] The adjective is recorded from 1878,[2] and the Shorter Oxford dates it to the early 20th century.[6] The noun extremism followed in 1849.[2]
