Forms

conventum n (genitive conventī); second declension[1]

Etymology

It is from Latin conveniō (“to come together, agree”), the neuter of its perfect participle used as a noun.[2][3][4] That verb is a compound of com- and veniō (“to come”), which goes back to Proto-Italic *gʷn-je/o- and Proto-Indo-European *gʷm-ie/o- (“to come”).[5]

Earliest recorded meaning

It is found in the Rhetorica ad Herennium, of agreements kept without laws, and in Cicero,[6][7] who speaks of constancy and truth in what is said and agreed.[6][4][8]

Semantic evolution

It was mainly a legal word for an agreement between parties: Cicero has stāre conventīs, to abide by agreements, and the pair pactum conventum, “a pact agreed”, or pacta conventa, which recurs in the jurists and in a formula from Baetica.[6][4][8] Livy speaks of arbiters of agreements, and Gellius of a secret agreement between two people about changing the order of letters.[6][4] The word is still used in the Code of Justinian in 530.[6]

Timeline

  • 81–43 BC – Cicero uses it of agreements and in the phrase pactum conventum.[6][7]
  • 59 BC–17 AD – Livy speaks of arbiters of agreements.[6][7]
  • c. 165 AD – Gellius uses it of a secret agreement.[6][7]
  • 530 AD – A law in the Code of Justinian uses it.[6]

Meanings

Noun

  1. An agreement, compact, covenant.[2][3][4]
  2. pactum conventum, pacta conventa: an agreed pact, agreements stipulated.[6][8]

Usage notes

It is distinct from conventus, an assembly or meeting, though both come from the same verb.[2][4]
