Pronunciation

  • Classical: [deˈuː.roː][1]
  • Ecclesiastical: [deˈuː.ro][1]

Forms

deūrō (present infinitive deūrere, perfect active deussī, supine deustum); third conjugation[1]

Etymology

It is from Latin dē- (“down, thoroughly”) + ūrō (“to burn”).[2][1][3] De Vaan traces ūrō to Proto-Italic *ouse/o- (“to burn”) and Proto-Indo-European *h₁eus-e/o- (“to burn”).[4] Cognate with Sanskrit ओषति (oṣati, “to burn, scorch”), Ancient Greek εὕω (heúō, “to singe”) and Old Norse ysja (“fire”).[4]

Earliest recorded meaning

The TLL records it from Lucilius on.[3] Its first sense is to burn up completely.[2][5]

Semantic evolution

It means to burn thoroughly or burn down.[2][6] Caesar uses it of the burnt screens of siege towers, the Bellum Hispaniense of a burnt town, and Livy of villages, crops and farmland burnt as the land was laid waste;[3][5][7] Tacitus has part of the Circus and the Caelian Hill burnt down.[7] Gellius uses it of burning books, and Minucius Felix of writings burnt in an assembly.[5] Lewis and Short call it frequent in the historians, rare elsewhere, and absent from Cicero.[7]

It was also used of cold and other forces that wither as if by burning:[2][8] Livy has a winter that had blighted the trees, Curtius coastal lands blasted by the north wind, and Seneca a serpent that scorches whatever its breath touches.[2][5]
