Forms

sēditiōsē (comparative sēditiōsius, superlative sēditiōsissimē)[1][2]

Etymology

It is from Latin sēditiōsus (“seditious, factious”) + -ē.[1][3] The adjective, found from Varro on, is formed from sēditiō (“violent discord, rebellion”),[1][4][5] which de Vaan lists among the derivatives of eō1 (“to go”), from Proto-Indo-European *h1ei- (“to go”).[5] Its prefix is sē- (“apart”), from the old ablative of the reflexive pronoun, ⟨*sēd⟩, which de Vaan explains as first meaning “for itself” and then “away, without”.[5]

Earliest recorded meaning

Köbler's first source is Cicero,[6] who uses it in the speeches for Cluentius and for Milo.[7]

Semantic evolution

It means seditiously, mutinously, in a factious way.[1][8] Cicero has the superlative in a letter to Atticus, of speaking in the most provocative way possible, and Tacitus has the comparative.[7][2]

British medieval Latin uses it for discordantly or factiously, of acts done in the course of a violent quarrel or feud, and for treacherously.[9]

Timeline

  • 81–43 BC – Cicero uses it, also in the superlative.[7][2][6]
  • 98–115 AD – Tacitus has the comparative seditiosius.[7][6]
  • 1285 – A British record uses it of a man who allied himself with Llywelyn, the late prince of Wales and enemy of the king.[9]
