Pronunciation

  • IPA: /ɪnˌθjuːzɪˈæstɪk/ (UK); /ɪnˌθuːziˈæstɪk/ (US)[1]

Etymology

It is partly borrowed from New Latin enthusiasticus and partly borrowed from Ancient Greek ἐνθουσιαστικός (enthousiastikós, “inspired”),[2] from ἐνθουσιαστής (enthousiastḗs, “one inspired”)[2][3] or ἐνθουσιάζω (enthousiázō, “to be possessed by a god”),[4][5] ultimately from ἔνθεος (éntheos, “possessed by a god”).[6] It is the adjective of enthusiasm and enthusiast.[2]

Earliest recorded meaning

Disparagingly, of people falsely claiming divine inspiration: 1578.[2] Merriam-Webster and Etymonline date the word from about 1600–1603, when it meant relating to possession by a god.[7][4]

Semantic evolution

For two centuries the word was mostly disparaging: it described religious movements that claimed direct inspiration (from 1578),[2] irrational delusion in religion (1690s),[4] and in other fields people moved by irrational impulses (1692 to 1850).[2] From 1632 it was also used of poetic inspiration.[2] The modern, approving sense, ardent and keen, appears from 1741,[2] and eager or pleased about something from 1777;[2] Etymonline dates the main modern sense to 1786.[4]
