Latin verruncō

Pronunciation

  • Classical: [aː.wɛrˈrʊŋ.koː][1]
  • Ecclesiastical: [a.verˈruŋ.ko][1]

Forms

āverruncō (present infinitive āverruncāre, perfect active āverruncāvī, supine āverruncātum); first conjugation[1] Old forms are the perfect subjunctive āverruncāssint in Pacuvius and the infinitive āverruncāssere, from an old future in -āssō.[2]

Etymology

It is formed from Latin ab- + verruncō (“to turn out”).[3][1] De Vaan lists it, from Cato on, under verrō (“to sweep”);[4] he thinks the simple verb is probably made from a lost noun, possibly preserved in the god Averruncus named by Varro, which presupposes a stem meaning “one who sweeps, one who wards off”.[4] The sweeping verb goes back to Proto-Italic *wors-e/o- and Proto-Indo-European *urs-e/o- (“to wipe”).[4] The OLD compares āverrō (“to sweep away”).[2] Varro, like the ancient grammarians after him, explained it from āvertō (“to turn away”).[3]

Earliest recorded meaning

Cato (234–149 BC)[5] uses it in a prayer in his treatise on farming, asking that calamities and bad weather be kept off: uti calamitates intemperiasque prohibessis, defendas averruncesque.[6]

Semantic evolution

Lewis and Short call it a very ancient word, peculiar to the language of religion.[6] It is used of warding off evils and prodigies: a line of Accius quoted by Cicero has di averruncent, “may the gods avert it”, and Livy speaks of rites performed to avert prodigies.[6] The word stayed rare; later writers who use it include Arnobius and Fulgentius.[3]
