Pronunciation

  • UK: /ɪnˈθuːziˌæst/, /-θjuː-/[1]
  • US: /ənˈθuziˌɪst/, /ɛn-/[1]

Etymology

It is borrowed from Late Latin enthusiasta (“a kind of heretic”), recorded from the 5th century, and its source borrowed from Ancient Greek ἐνθουσιαστής (enthousiastḗs, “a person possessed or inspired”),[2][3][4][5] an agent noun from ἐνθουσιάζω (enthousiázō, “to be inspired or possessed by a god”),[2][4][5] itself from ἔνθεος (éntheos, “possessed by a god”), from ἐν (en, “in”) and θεός (theós, “god”).[4][6] The Oxford Dictionary of English and the Shorter Oxford allow that it came partly through French enthousiaste, which the OED dates to 1544.[6][7][2] The OED notes that the disparaging religious sense followed German Enthusiast, used by Luther in 1524.[2] The word's later senses were influenced by enthusiasm.[2]

Earliest recorded meaning

As a plural name, the Enthusiasts, members of a supposed ancient Christian sect who claimed direct inspiration from the Holy Spirit: 1536, in Richard Taverner's translation of Melanchthon.[2] Merriam-Webster dates the word to 1570, Etymonline to the 1560s.[8][4]

Semantic evolution

Through the 16th and 17th centuries the word was a term of abuse for a person who falsely claimed divine revelation, and for members of various Christian groups (1548);[2][4] Johnson (1755) still defined it as someone who vainly imagines a private revelation.[9] From 1612 it was also used of a person possessed by a god or spirit, in a frenzy.[2] The general sense, a person who pursues a cause or activity with passion, appears in 1748 and became milder over time,[2][4] and since 1835 it has been combined with a noun naming the interest, as in football enthusiast.[2] Collins keeps the religious sense as archaic.[10]
