Pronunciation

  • Classical: [ˈɔp.strɛ.poː][1]
  • Ecclesiastical: [ˈɔb.stre.po][1]

Forms

obstrepō (present infinitive obstrepere, perfect active obstrepuī, supine obstrepitum); third conjugation[1] It is also spelled ops-.[2][3]

Etymology

It is from Latin ob- + strepō (“to make a noise”).[2][3][1] The verb strepō goes back to Proto-Italic *strepe/o-; de Vaan doubts that it is inherited from the parent language, since it is found only in Latin and Germanic.[4] Cognate with Old Norse þrefa (“to quarrel”) and Old English þræft (“quarrel”).[4]

Earliest recorded meaning

Köbler's first source is Cicero,[5] who speaks of orators who seem in a way to drown themselves out when they speak.[2]

Semantic evolution

It is to make a louder noise against someone or something, often of disturbing an activity, as in Pliny the Younger's household whose games and his studies do not disturb each other.[2] Transitively it is to drown with noise, as in Cicero's deeds that seem drowned by the shouting of soldiers.[2] Horace uses it of the violent Aufidus roaring and of the sea resounding at Baiae.[2][6] Seneca has it of clamouring against something, and Pliny the Elder of a thing that counteracts another.[2]

Timeline

  • 81–43 BC – Cicero of drowning one's own speech and of soldiers' shouting.[2][5]
  • 65–8 BC – Horace of the roaring river Aufidus.[2][5]
  • 4 BC–65 AD – Seneca of protesting with prayers.[2][5]
  • 23/24–79 AD – Pliny the Elder of a counteracting effect.[2][5]
