Forms

cōnsessus m (genitive cōnsessūs); fourth declension[1]

Etymology

It is from Latin cōnsīdō (“to sit down together”) + -tus, a noun of action.[2][3] The verb is con- and sīdō (“to sit down”), which de Vaan traces to Proto-Italic *sizd-e/o- and the reduplicated present Proto-Indo-European *si-sd-e/o- (“to sit down”).[4] Cognate with Umbrian sistu (“let him sit down”), Sanskrit सीदति (sī́dati, “sits down”) and Ancient Greek ἵζω (hízō, “to sit down”).[4]

Earliest recorded meaning

Its first example in the OLD is in Afranius, who speaks of “our meeting or gathering”.[2][5]

Semantic evolution

In Classical Latin it is a gathering or assembly of people sitting together, especially a court of jurors, as in Cicero's speeches, and the audience in a theatre or at games.[2][6] An inscription uses it for the right to a seat.[2] The abstract sense, a sitting together or the permission to sit beside someone, is only post-classical, in the Historia Augusta and the Theodosian Code.[6] Church Latin glosses it “assembly, a sitting together”,[7] and in British medieval Latin consessus Regius was the court of King's Bench.[8]

Timeline

  • 2nd half of the 2nd century BC – Afranius of a gathering.[2][5]
