Forms
sēditiōsus (feminine sēditiōsa, neuter sēditiōsum, superlative sēditiōsissimus); first/second-declension adjective[1]
Etymology
It is formed from sēditiō (“violent discord, rebellion”) with the suffix -ōsus.[2][3][1] De Vaan lists ⟨sēditiō⟩ among the compounds of eō (“to go”), with the prefix ⟨sēd-⟩ “apart”, from Proto-Italic *ei- and Proto-Indo-European *h₁ei- (“to go”).[4]
Earliest recorded meaning
Cato in a speech has “he began to speak seditious words”;[2] de Vaan dates it from Varro,[4] Köbler from Cicero.[5]
Semantic evolution
It is given to or guilty of rebellion or mutiny, factious, as Cicero's states that put seditious men in charge, and of words and acts seditious, as in Cato.[2][3] Of times and conditions it is full of civil strife or turbulent, as Cicero's clever men who left a turbulent life for quiet study.[2][1] Wiktionary adds quarrelsome and troubled.[1]
Church Latin glosses it “seditious, factious, mutinous, turbulent”, and as a noun “conspirator”;[6] Köbler finds it in councils, formulae and the Bavarian law code.[5] Döderlein makes sēditiō a political commotion arising from clear differences of opinion, unlike turbae and tumultus, which disturb public order and peace.[7] English seditious (mid-15th century) is from it, partly through Old French.[8]
