Pronunciation

  • Classical: [ˈdʊk.tʊs][1]
  • Ecclesiastical: [ˈduk.tus][1]

Forms

ductus m (genitive ductūs); fourth declension[1] An inscription has a neuter ductum.[2][3]

Etymology

It is from Latin dūcō (“to lead, draw”) + -tus, a fourth-declension action noun.[2][3][1] De Vaan traces dūcō to Proto-Italic *douk-e- and Proto-Indo-European *deuk-e/o- (“to draw”).[4] Cognate with Middle Welsh dwc (“leads, brings”) and Albanian nduk (“to pull”).[4]

Earliest recorded meaning

De Vaan and Köbler date it from Plautus,[4][5] who in the Amphitruo speaks of a commander who conducted the state's business under his own command.[2]

Semantic evolution

Its first sense is military leadership or command, and Ovid uses it figuratively of a girl captured under his leadership.[2] It also means the conveyance of water, and aquae ductus, also written as one word, is an aqueduct, as in Cicero's letters and Frontinus' work on the aqueducts of Rome.[2][6] It means a movement in a particular line, as Seneca's carver guiding his skilled hand along the breast, a line drawn or an outline, and a linear arrangement, as Cicero's line of the city wall.[2] In rhetoric it is a line of treatment, as in Quintilian.[2] It also means drawing or pulling, as Columella's pruning done with a draw of the knife, and a draught of fish.[2]

Church Latin glosses it leadership, direction, purpose, and the swing of a censer.[7] In medieval Latin it can mean carting.[8] English borrowed duct in the 1640s.[9]
