Pronunciation

  • IPA (Classical): [ˈsaː.nɪ.taːs][1]
  • IPA (Ecclesiastical): [ˈsaː.ni.tas][1]

Forms

sānitās f (genitive sānitātis); third declension[1]

Etymology

It is from Latin sānus (“healthy, sane”) + -tās.[2][1] De Vaan reconstructs ⟨sānus⟩ as Proto-Italic *sāno-, mechanically Proto-Indo-European *seh₂-no-, and suggests it may be from a root “to tie” (“in place, in order”) or from the root “to satisfy” of satis.[3]

Earliest recorded meaning

The OLD's earliest citation is Plautus, of health.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant healthy condition, health of body; from Cicero soundness of mind, sanity, good sense, as in ad sānitātem redīre “to come to one's senses”; and in rhetoric the soundness of a style free of faults.[2][5]

In Ecclesiastical Latin it means soundness, health, sanity, and Medieval Latin used it for a miraculous cure.[6][7] English sanity (early 15th century, first “health”) is from it, and it survives as French santé, Italian sanità and Romanian sănătate.[8][1]

Timeline

  • c. 250–184 BC – Plautus uses it of health.[2][4]
  • 81–43 BC – Cicero uses it of soundness of mind and of style.[2][4]
  • early 15th century – English sanity is recorded.[8]
