Etymology

It is from argūmentor “to argue” with the suffix -tiō; ⟨argūmentor⟩ is from argūmentum, from arguō “to make clear, prove”.[2][1][3] De Vaan traces ⟨arguō⟩ to Proto-Italic *argu- (“bright”), from Proto-Indo-European *h₂erǵ-u- (“white”).[4]

Earliest recorded meaning

The OLD's earliest citation is from the Rhetorica ad Herennium, of a line of argument.[2] Köbler dates it 86/82 BC.[5]

Semantic evolution

A rhetorical term, most frequent in Cicero, it was the presentation of arguments for a case, argumentation, and a particular proof or line of argument.[2][6][7]

In Ecclesiastical Latin it was argument, debate, proof, evidence.[8] British Medieval Latin used it for argument, reasoning, as in Aldhelm in 671.[9] English argumentation came through Old French in the mid-15th century.[3]
