Forms

congressus m (genitive congressūs); fourth declension[1]

Etymology

It is from Latin congredior (“to meet”) + -tus, an action noun.[2][1] Congredior is from con- and gradior “to step”.[1]

Earliest recorded meaning

Köbler's first source is Cicero, who says of Vatinius that nobody thinks him worth meeting or approaching.[3][2] Köbler dates Cicero 81–43 BC.[3]

Semantic evolution

It meant a coming together in a friendly or hostile way.[4] As a friendly meeting it was an encounter, interview or conference, often contrasted by Cicero with digressus “parting”, then social intercourse and companionship.[2][5] Lucretius uses it of the coming together of matter, and Cicero of an agreement made by meeting.[2]

As a hostile meeting it was an engagement with an enemy, as Cicero's comparison with the gladiatorial combat of life.[2] Gaffiot also gives the sense of sexual intercourse.[5] Medieval Latin kept the senses of meeting, clash and battle, and British sources used it of a voyage.[6][7] English congress is recorded about 1400, and in the sense of a meeting of people from the 1520s.[8]
