Pronunciation

  • IPA (Classical): [ˈaːr.dɔr][1]
  • IPA (Ecclesiastical): [ˈar.dor][1]

Forms

ārdor m (genitive ārdōris); third declension[1]

Etymology

It is from Latin ārdeō (“to burn”) + -or.[2][3][1]

Earliest recorded meaning

Köbler's earliest source is Plautus, and the OLD's earliest citations are Accius, of fire, flashes of light and heat.[4][2] Köbler dates Plautus c. 250–184 BC and Accius 170–c. 90 BC.[4]

Semantic evolution

It meant a burning, fire, as in Cicero's house whose blaze threatened the city; a flash or gleam of light; fierce heat, as of the sun in Lucretius; and figuratively agitation of mind, passion, eagerness, ardour, as in Cicero; passionate love, as in Lucretius; and intensity, violence.[2][5][6]

In Ecclesiastical Latin it means burning.[7] British Medieval Latin used it for fire, heat, passion and ferocity.[8] English ardour (mid-15th century) is from it through Old French, and French ardeur is inherited from it.[9][1]
