argūmentōsus (feminine argūmentōsa, neuter argūmentōsum); first/second-declension adjective[1]
Etymology
It is from Latin argūmentum (“argument, subject matter”) + -ōsus, from arguō (“to make clear, prove”).[2][1][3] ⟨arguō⟩ goes back, according to de Vaan, to Proto-Italic *argu- (“bright”), from Proto-Indo-European *h₂erǵ-u- (“white”).[4]
Earliest recorded meaning
Its earliest source is Quintilian.[3][5] Köbler dates Quintilian c. 35–95/96 AD.[3]
Semantic evolution
It meant abounding in subject matter, rich in matter, carefully worked, as of a work in Quintilian, and rich in proof, argumentative, as in Sidonius and Acron.[2][6][5]
In Ecclesiastical Latin it meant rich in material or proof, busy.[7] Medieval Latin used it for skilled in argument and for contriving.[8] British Medieval Latin used it for assiduous, busy, as an epithet of the bee, for persuasive, convincing, and for ingeniously contrived.[9] English argumentose and Spanish argumentoso are from it.[1]
