Pronunciation

  • IPA (Classical): [seːˈkuː.rɪ.taːs][1]
  • IPA (Ecclesiastical): [seˈkuː.ri.tas][1]

Forms

sēcūritās f (genitive sēcūritātis); third declension[1]

Etymology

It is from Latin securus (“free from care”) + -tās.[2][1]

Earliest recorded meaning

Cicero writes to Atticus that he will see a wonderful unconcern, and uses it for Democritus' calm of mind, Greek Ancient Greek εὐθυμία (euthumía).[2][3] Köbler dates Cicero 81–43 BC.[4]

Semantic evolution

It meant freedom from anxiety, calmness, and of manner assurance, as Quintilian's unaffected style.[2] In a bad sense it was complacent carelessness, as in Curtius.[2][5] It also meant freedom from danger, safety, as Velleius' hope of lasting security for the empire, and immunity from punishment.[2] Personified, Sēcūritās appears on imperial coins, and Ulpian uses it of security for a debt.[2]

In medieval Latin it was a safe-conduct, a promise not to take revenge or do violence, and a document containing such a promise.[6] English security is recorded in the early 15th century, and surety came through Old French seurté around 1300.[7]
