fanaticus

Etymology and origin of the Latin word fanaticus

History

Pronunciation

  • IPA (Classical): [faːˈnaː.tɪ.kʊs][1]
  • IPA (Ecclesiastical): [faˈnaː.ti.kus][1]

Forms

fānāticus (feminine fānātica, neuter fānāticum, adverb fānāticē); first/second-declension adjective[1]

Etymology

It is formed from fānum “temple, shrine” with the suffix -āticus.[2][1][3] Fānum is related to festus “festive”, according to Etymonline.[3] Some ancient writers derived it from Faunus.[4]

Earliest recorded meaning

Köbler and the TLL date it from Cicero,[5][4] who calls a man a homo fanaticus, a fanatic, for attending a rite out of an old woman's superstition.[2]

Semantic evolution

Its first sense was “of a temple”, as in an inscription recording temple funds (pecunia fanatica), and as a noun it meant a temple servant or devotee, especially of Bellona or Cybele.[2][6] Festus records that a tree struck by lightning was called fanatica.[2] More often it meant inspired by orgiastic rites, frenzied, as of the eunuch priests of Cybele in Livy, and then frantic or mad in general, as in Cicero's “superstitious and almost fanatic philosophers”.[2][6]

In Christian Latin it meant pagan or of pagan ritual, and as a noun a pagan priest or a heathen.[7] English borrowed it in the 1520s as English fanatic, first meaning “insane person”, and the sense “zealous person” followed in the 1640s.[3]
