Forms

conventiō f (genitive conventiōnis); third declension[1]

Etymology

It is from conveniō “to come together, agree” with the suffix -tiō.[2][3][1] The OLD calls it a doublet of contiō “assembly”, the contracted form of the same word.[2] The Senatus consultum de Bacchanalibus (CIL 1.581) has the archaic ablative ⟨conventionid⟩.[2][4]

Earliest recorded meaning

The OLD's earliest citation is the inscription CIL 1.581, where it means an assembly of the people, the sense contiō usually has.[2] The TLL notes that apart from a few places it is not read before Sallust.[4]

Semantic evolution

Varro uses it of an assembly, and Paulus' epitome of Festus glosses in conventione as in contione.[3][2] In law it meant a woman's passing into her husband's control (in manum conventio), as in Gaius, and the suing of a defendant, as in Ulpian.[2] From Sallust onwards it meant an agreement, compact or covenant, the sense Livy, Seneca and the Digest use.[2][3] The TLL says it becomes frequent from the 3rd century AD.[4]

In Ecclesiastical Latin it meant an agreement, concord, or an assembly.[5] Medieval Latin added the senses of a religious community, a convent, and in law a summons or claim.[6] English convention came into English in the early 15th century, both as “a formal agreement” and as “a formal meeting”.[7]
