Pronunciation

  • Classical: [ˈpro.ʊt][1]
  • Ecclesiastical: [ˈprɔː.ut][1]

Forms

prout [1] Horace scans it as one syllable.[2]

Etymology

It is formed from prō (“in front of; in proportion to”) and ut (“as”).[2][1][3] De Vaan derives ⟨prō⟩ from Proto-Italic *prō and Proto-Indo-European *pro (“in front of, before”), cognate with Oscan pru (“before, for”) and Ancient Greek πρό (pró, “before, forth”), and ⟨ut⟩ from Proto-Italic *kʷutV(s) (“how”), from the interrogative stem Proto-Indo-European *kʷu- (“where, how”), cognate with Oscan puz (“that, as”).[4]

Earliest recorded meaning

Köbler gives Cicero as its first author,[3] who speaks of silver plate that was enough “as the means of a man of Thermae allowed”.[2]

Semantic evolution

It is according as or in proportion as, as in Cicero, and with ita it introduces alternatives, according to whether … or, as Seneca's animals coloured according to whether they receive the light straight or slanting.[2] It is also in so far as or inasmuch as, as Livy's small golden crown given to Jupiter “inasmuch as their means were not great”.[2][1]

Church Latin glosses it “according to, in proportion to, just as, insofar as”,[5] and in medieval Latin it is also in order that.[6] Köbler finds it often in charters, councils and the law codes.[3]

Timeline

  • 81–43 BC – Cicero in the sense “according as”.[2][3]
  • 59 BC–17 AD – Livy in the sense “inasmuch as”.[2][3]
