Forms

seguridad f (plural seguridades)[1]

Etymology

It is inherited from Old Spanish seguridat, inherited from Latin sēcūritās (“freedom from care; safety; guarantee”).[2][1][3] Corominas lists it among the derivatives of seguro, with the form in ⟨-t⟩ in Berceo, and notes that the earlier word was seguranza, still used in Salamanca and Asturias.[4][5] Nascentes calls the Portuguese word semi-learned.[6]

The same Latin word is Catalan seguretat, Portuguese seguridade and Italian sicurtà.[7][8][9] French borrowed it as sécurité about 1190, but used it little before the 18th century.[10]

The Latin noun is formed from sēcūrus (“free from care, safe”), itself from sē- (“without”) and cūra (“care”).[11][1][12] De Vaan traces the last to Proto-Italic *kʷoisā- (“care, watch”) and Proto-Indo-European *kʷeis- (“to heed”).[12]

Earliest recorded meaning

The CDH's first record is in Berceo's Vida de Santo Domingo de Silos (c. 1236, in a late 13th-century copy), where the saint is said to win safety for pilgrims: a los peregrinantes gana seguridad.[13] The Aragonese Vidal Mayor (c. 1250) uses seguridat in the legal sense “surety”: De dar fiança o seguridat.[13]

Semantic evolution

Nebrija glosses it with Latin securitas and otium “ease”, and Percyvall (1591) with English “safetie”.[14][15] The Diccionario de Autoridades (1739) defined three senses: the state of things that makes them firm and free from risk, certainty, and a surety or bond of indemnity, mostly in money matters.[16] The Academy's 1884 edition gave the etymology from Latin securitas.[17]

The legal sense “surety” is common in documents from the Americas, from Nicaragua in 1529 on.[18] Today it is obsolete, while the word has gained the sense of a service that guards a person, firm or building, and fixed phrases such as seguridad social “social security” and seguridad ciudadana “public safety”.[2][19] Moliner's senses range from firmness and certainty to protection against risk and self-assurance.[20]

Timeline

  • c. 1236 – Berceo's Vida de Santo Domingo de Silos;[13] Corominas dates the word 1220–1250.[13][5]
  • c. 1250 – seguridat “surety” in the Vidal Mayor.[13]
  • 1513 – Nebrija's Vocabulario glosses it with securitas and otium.[14]
  • 1529 – first record from the Americas, in Nicaragua.[18]
  • 1591 – Percyvall translates it “safetie”.[15]
  • 1739 – the Diccionario de Autoridades defines three senses.[16]
  • 1884 – the Academy's dictionary derives it from Latin securitas.[17]
