Pronunciation

  • IPA (Classical): [kɔn.tɛn.tiˈoː.sʊs][1]
  • IPA (Ecclesiastical): [kon.ten.t͡siˈɔː.s̬us][1]

Forms

contentiōsus (feminine contentiōsa, neuter contentiōsum); first/second-declension adjective[1]

Etymology

It is from Latin contentiō (“struggle, dispute”) + -ōsus, from contendō “to strain, contend”, from con- and tendō “to stretch”.[2][1][3] De Vaan traces ⟨tendō⟩ to Proto-Italic *tend-, Proto-Indo-European *ten-d(ʰ)- (“to stretch”).[4]

Earliest recorded meaning

Gaffiot cites Pliny the Younger, and Köbler's earliest source is Suetonius.[5][6] Köbler dates Suetonius c. 75–c. 150 AD.[6]

Semantic evolution

It meant argumentative, quarrelsome, contentious, as in Pliny, of a debate full of struggle; and in Apuleius persistent, obstinate.[2][5]

In Ecclesiastical Latin it means contentious, rebellious.[7] Medieval Latin used it for one refusing his duty, and iūrisdictiō contentiōsa was jurisdiction in civil disputes.[8][6] English contentious (early 15th century) is from it.[3]

  • c. 125–175 AD – Apuleius uses it of obstinacy.[2][6]
