Ultimate origin
Latin (trahō)

Forms

tractātus m (genitive tractātūs); fourth declension[1]

Etymology

It is from tractō “to handle, treat” with the suffix of action nouns -tus.[2][1][3] ⟨Tractō⟩ is the frequentative of trahō “to draw”.[1]

Earliest recorded meaning

The OLD's earliest citation is from Cicero, of the management of an activity.[2] Köbler's first source is Livy; he dates Cicero 81–43 BC.[4]

Semantic evolution

Its literal sense, a handling, touching, is rare and not in Cicero, as Pliny's handling of nuts and plants tamed by handling like wild beasts.[5][2] It meant the management or exercise of an activity, as in Cicero and Quintilian, the treatment or discussion of a subject, a method of treatment, and in Ulpian the consideration of a proposal.[2][3]

In Ecclesiastical Latin it meant a tract, treatise, sermon, homily.[6] Medieval Latin used it of a treatise or written exposition and of a homily, and British Medieval Latin also of a haul of fish.[7][8] Old French traitié “agreement, dealings” gave English treaty in the late 14th century, and English tractate is a learned borrowing.[9][1]
