Pronunciation

  • Classical: [ˈsʊp.tʊs][1]
  • Ecclesiastical: [ˈsub.tus][1]

Forms

subtus (not comparable)[1] Also spelled suptus.[2]

Etymology

It is from Latin sub (“under”) with the ending of intus (“within”),[2][3][4]

Earliest recorded meaning

Köbler and Lewis & Short record it in Plautus,[5][3] and de Vaan dates it from Cato;[4] it meant “below, underneath”.[2]

Semantic evolution

It was mostly an early Latin word, found in Cato, Varro and Livy but not in Cicero or Caesar.[3] Livy tells how the Romans attacked with siege works above ground, while subtus Macedones cuniculis oppugnabant “the Macedonians attacked from below with tunnels”.[3] Vitruvius already uses it as a preposition with the accusative,[2][6] and this use spread in Late Latin, in the Vulgate and the grammarians,[7][6] and in medieval Latin, meaning “beneath, under”.[8] It is the source of Italian sotto,[6][1] Romanian subt and Friulian sot.[1]

Timeline

  • c. 250–184 BC – Plautus uses it.[5][3]
  • 234–149 BC – Cato uses it in On Agriculture.[4][6][5]
  • c. 84–c. 25 BC – Vitruvius uses it as a preposition.[2][6][5]
  • 59 BC–17 AD – Livy writes of the Macedonians attacking from below with mines.[3][5]
