Pronunciation

  • Classical: [fak.tiˈoː.sʊs][1]
  • Ecclesiastical: [fak.t͡siˈɔː.s̬us][1]

Forms

factiōsus (feminine factiōsa, neuter factiōsum); first/second-declension adjective[1]

Etymology

It is from Latin factiō (“faction, party”) + -ōsus.[2][1][3] factiō is a noun of faciō “to make, do”, which de Vaan traces to Proto-Italic *fak-i- and Proto-Indo-European *dʰh₁-k- (“to make”), from the root Proto-Indo-European *dʰeh₁- (“to put”).[4] Varro explained it from doing things together, as he explained axitiōsae from acting together, and Festus says both were used of people doing something jointly.[3]

Earliest recorded meaning

Köbler dates it from Plautus,[5] who has busy tongues and idle hands, and a man described as rich and influential.[2][6]

Semantic evolution

It is first busy or active, then having a powerful following or connections, influential.[2] From that it is belonging to or forming a faction, factious or turbulent: Cicero writes of men who become bribers and party men to gain the greatest power.[2][6] Lewis & Short call it classical and give sēditiōsus, turbulentus and praepotēns as related words.[6] Church Latin glosses it quarrelsome,[7] and in Medieval Latin it is a person engaged in a feud.[8]

Timeline

  • c. 250–184 BC – Plautus of a busy tongue and an influential man.[2][5]
  • 81–43 BC – Cicero of factious men seeking power.[2][5]
