Pronunciation

  • Classical: [sʊ.pɛr.waˈkaː.ne.ʊs][1]
  • Ecclesiastical: [su.per.vaˈkaː.ne.us][1]

Forms

supervacāneus (feminine supervacānea, neuter supervacāneum); first/second-declension adjective[1] It is also spelled ⟨supervacuāneus⟩, in Cicero's De natura deorum and in Sallust.[2][3]

Etymology

It is from Latin super- (“over, above”) + vacō (“to be empty”) + -āneus.[2] Lewis and Short and Georges take the second part from vacuus (“empty”).[4][5] De Vaan lists it among the derivatives of vacō, which goes back to Proto-Italic *wako- (“empty”) and Proto-Indo-European *h₁uh₂-ko-.[6]

Earliest recorded meaning

Köbler and de Vaan date it from Cato,[7][6] whose farm manual lists spare presses and windlasses for the press room, extra to those in use.[2][4]

Semantic evolution

Its first sense is additional or spare.[2][5] Cicero's supervacanea opera is work done in spare hours, as in the De senectute.[4][3] More often it means superfluous or redundant:[2][8] Cicero uses it of whatever in a tree is superfluous and has no use, Sallust writes that it is needless to discuss something, and Livy uses it of a useless speech and of a consul held to be superfluous.[2][3][5] Of letters and other acts it means needless, serving no purpose, as when Cicero fears that his letters will be thought unnecessary.[2][4]

Ecclesiastical Latin used it for superfluous,[9] and British medieval writers for superfluous, redundant and needless.[10]

Timeline

  • 234–149 BC – Cato uses it of spare equipment for a press room.[2][7]
  • 81–43 BC – Cicero uses it of superfluous things and needless letters.[2][7]
  • 86–34 BC – Sallust uses the form supervacuāneus.[2][7]
  • 59 BC–17 AD – Livy uses it of a useless speech.[5][7]
