Ultimate origin
Proto-Indo-European (*wert-)

Pronunciation

  • Classical: [ˈproːr.sʊs][1]
  • Ecclesiastical: [ˈprɔr.sus][1]

Forms

prōrsus (not comparable)[1] Manuscripts of Plautus read prōsus throughout, and the spelling also appears in Varro, Cicero and Seneca.[2] An uncontracted prōversus is also recorded.[3]

Etymology

It is a contraction of ⟨*prōvorsus⟩, from prō (“forward”) and vorsus, the old form of versus (“turned”), the participle of vertō (“to turn”).[2][3][1] De Vaan derives the verb from Proto-Italic *wert-e/o- and Proto-Indo-European *wert-e/o- (“to turn”), cognate with Umbrian kuvertu (“let him turn back”).[4]

Earliest recorded meaning

Köbler gives Plautus as its first author,[5] who has “you are an absolutely unique poet for this” in the Asinaria;[2] Ennius has a wave that rolls forward and back.[2]

Semantic evolution

In early Latin it is forwards, straight ahead, often with rūrsus, as in Ennius, and straight to a place without stopping, as Terence's “see that he doesn't rush straight here”.[2][6] Its usual sense is thoroughly, absolutely, utterly, before or after the word it strengthens, often with a negative, as Plautus' “there is no way the girl will not be given a dowry”, and with demonstratives, as Cicero's “I feel exactly as you write”.[2][6] After et it marks the stronger of two terms, and it links a clause to what precedes, in fact, in short, as Sallust's summing up of Catiline's face: “in short, madness was in his face and look”.[2]

The adjective is straight or direct, mostly post-Augustan, and prōrsa ōrātiō is straightforward speech, prose, whence the noun prōsa.[6][1] Church Latin glosses it “wholly, absolutely, straight on, precisely, certainly”.[7]

  • c. 250–184 BC – Plautus in the sense “absolutely”.[2][5]
