Pronunciation

  • Classical: [kõː.fɫaˈɡraː.ti.oː][1]
  • Ecclesiastical: [koɱ.flaˈɡrat.t͡si.o][1]

Forms

cōnflagrātiō f (genitive cōnflagrātiōnis); third declension[1]

Etymology

It is formed from Latin cōnflagrō (“to burn up”) + -tiō.[2][3] The verb is a compound of flagrō (“to blaze”),[1] which goes back to Proto-Italic *flagro- and Proto-Indo-European *bʰl̥g-ro- (“burning”).[4]

Earliest recorded meaning

Seneca has it first, in the Natural Questions, setting the flood that covered all the plains beside the burning in which most living things were parched.[3][2]

Semantic evolution

It was a rare, post-Augustan word.[5] Suetonius used it for the eruption of Vesuvius,[2][6] Lactantius of perishing by fire,[6] and Arnobius in the plural.[3] Theological writers applied it to the burning of the world at the end of time.[7]

Medieval Latin used it for fires of every kind: a city burnt by fire from heaven, the burning of castles in war, subterranean fire and the fire of hell, and in philosophy and theology for the world-conflagration.[7][8] English conflagration (1550s) comes from it, through French or directly.[9]

Timeline

  • 4 BC–65 AD – Seneca contrasts a universal flood with a universal burning.[3][10]
  • c. 75–c. 150 AD – Suetonius uses it for the eruption of Vesuvius.[2][10]
  • c. 250–317 AD – Lactantius speaks of perishing by fire.[6][10]
  • 354–430 AD – Augustine uses it in the plural, in the City of God.[3][10]
  • 1550s – English borrows it as conflagration.[9]
