Pronunciation

  • Classical: [a.dɔˈpɛ.ri.oː][1]
  • Ecclesiastical: [a.doˈpɛː.ri.o][1]

Forms

adoperiō (present infinitive adoperīre, perfect active adoperuī, supine adopertum); fourth conjugation[1]

Etymology

It is from Latin ad- + operiō (“to cover”).[2][3][4] De Vaan traces the simple verb to Proto-Italic *op-wer-i(e)- (“to cover up”) and Proto-Indo-European *h₂uer-i(e)- (“to cover”);[5] it is the counterpart of aperiō (“to open”), with the prefix ⟨op-⟩ in place of ⟨ap-⟩.[5]

Earliest recorded meaning

The TLL finds it first in Virgil,[3] who has purpureo adopertus amictu, “covered with a purple cloak”, in the Aeneid.[6][7]

Semantic evolution

Lewis & Short note that it is not used before the Augustan period and mostly in the perfect participle.[6] Livy has capite adopertō, “with the head covered”;[6][8] Ovid writes of ground covered with flowers and of eyes veiled by sleep, adoperta lumina somno;[6][9][8] Columella of eggs covered with salt and of a vine shoot covered with earth.[7][8] It could also mean to shut a door.[8][4] Festus explains the Italian custom of veiling the head by Aeneas having covered his.[3] Medieval writers use it of people dressed in poor clothes and, figuratively, of people seized by terror.[10]
