Forms

conciencia f (plural conciencias)[1] Old Spanish texts spell it conciencia, conçiencia, conciençia and, closer to Latin, consciencia.[2] A form congencia occurs at the end of the 14th century in Pedro de Veragüe.[3]

Etymology

It is borrowed from Latin cōnscientia (“knowledge, consciousness”), a learned word like the rest of the family of ciencia.[3][4][1] The DLE and Wikcionario add that the Latin noun is a calque of Ancient Greek συνείδησις (suneídēsis).[5][6]

The Latin word is formed from cōnsciēns, the present participle of cōnsciō (“to know together, be aware”), with the suffix -ia.[3][7][1] The verb is con- added to sciō (“to know”).[7] Its first sense was knowledge shared with someone else; the sense of knowledge of oneself, and with it the moral sense, came later.[8][9]

Beside it Spanish has consciencia, a spelling closer to the Latin, which the DLE keeps for awareness and consciousness rather than for the moral sense.[10] The DTME notes that both spellings appear in the 13th century, ⟨conciencia⟩ in 1256 and ⟨consciencia⟩ in 1270, and that the hesitation between them has lasted to the present.[11]

Earliest recorded meaning

Corominas's first record is the Partidas of Alfonso X.[3][12] There it is the inner knowledge of good and evil: the law quotes Saint Augustine, sol que mi conciencia no me acuse delante Dios “so long as my conscience does not accuse me before God”.[13][14] The CDH has an earlier hit in the Libro de los doce sabios (dated c. 1237), but in a copy of the late 14th or early 15th century.[14]

Semantic evolution

Covarrubias in 1611 explains it, after Nebrija, as knowledge of oneself and of the good or evil in one's mind, and records ancho de conciencia “not scrupulous” and en mi conciencia “upon my word”.[15] Autoridades in 1729 calls it a purely Latin word and keeps the same definition.[16] The Academy's 1817 edition defines the phrase a conciencia as said of work done solidly and without fraud.[17]

The psychological sense, the mind's knowledge of itself, leads the definition in the Academy's 2001 edition.[18] The current DLE puts the moral senses first and refers the sense of being awake and aware to consciencia.[5] Phrases include conciencia de clase “class consciousness”.[5] In 1855 Baralt criticised con toda seguridad de conciencia as a pedantic Gallicism, preferring en conciencia and a conciencia.[19]

Timeline

  • a1260 – a mid-13th-century manuscript of the New Testament has mi conciencia, “my conscience”.[14]
