vacuitās f (genitive vacuitātis); third declension[1]
Etymology
It is from Latin vacuus (“empty”) + -tās.[2][1] De Vaan reconstructs a Proto-Italic adjective ⟨*wako-⟩ “empty”, from Proto-Indo-European *h₁uh₂-ko-, behind vacō and ⟨vacuus⟩, with Umbrian ⟨anter.vakaze⟩ “let there be an interruption” as a cognate.[3]
Earliest recorded meaning
Köbler's earliest source is Cicero, and the OLD's earliest citations include Cicero and Vitruvius.[4][2] Köbler dates Cicero 81–43 BC.[4]
Semantic evolution
It meant an unoccupied state, emptiness, an empty space, as in Vitruvius; freedom from something undesirable, as in Cicero's vacuitās dolōris “absence of pain”; and freedom from occupation, leisure.[2][5]
In Ecclesiastical Latin it means vanity, emptiness.[6] Medieval Latin used it for leisure, idleness.[7] English vacuity (late 14th century) is from it.[8]
