Pronunciation

  • /ˈθjenθja/, [ˈθjẽn̟.θja], /ˈsjensja/[1]

Forms

ciencia f (plural ciencias)[1] Old Spanish writes çiençia, sciencia and ciencia, and also siencia and esciencia; the DCECH dates esciencia to about 1310.[2][3] Asturian has cencia.[3]

Etymology

It is inherited from Old Spanish çiençia, borrowed from Latin scientia (“knowledge”), a learned word.[3][4][5][1] The Latin noun comes from sciēns (“knowing, one who knows”), the present participle of sciō (“to know”), with the suffix -ia.[3][6][1] De Vaan thinks the verb is probably a back-formation from nesciō (“not to know”) and traces it to *skh₁-i- (“to incise”), “to know” having developed from “to distinguish, decide”.[7]

The DCECH notes that the other Spanish words of this family are learned too, such as conciencia and consciente, and also necio, from nescius (“ignorant”).[3]

The same Latin noun was taken as Portuguese ciência and French science, which is recorded from 1080.[8][9]

Earliest recorded meaning

The Semejanza del mundo of about 1223 has arte que dizen ares magica que es çiencia de naturas “the art they call magic, which is the knowledge of natures”.[10] The DCECH's first record is Berceo, whose Vida de San Millán (c. 1230, in an 18th-century copy) says Quanto en la cïencia era más embevido, tanto en la creencia era más encendido “the more he was steeped in learning, the more he burned in faith”.[3][10] The Breve diccionario dates it 1220–1250.[4]

Semantic evolution

Alfonso X's prose already uses the word for certain knowledge of things through their principles and causes, for a particular body of doctrine, as la sciencia de la astrologia, and for learning.[11] Covarrubias in 1611 defined it as certain knowledge of a thing through its cause, and traced it to the Latin verb for “to know”.[12] The Diccionario de Autoridades called the faculties of theology, philosophy, law and medicine ciencias, and recorded ciencia infusa, knowledge inspired by God as to Solomon, and cierta ciencia, full knowledge, a formula of royal grants.[13] The formula is found in Mexico in 1532: de su proprio motu e ciencia cierta.[14]

Salvá in 1846 recorded ciencias exactas and ciencias naturales, and the Academy's dictionary of 1884 gave the senses still found today: knowledge through principles and causes, a body of doctrine, learning, and skill in anything.[15][16] The DLE now defines it as knowledge obtained by observation and reasoning, from which testable laws are drawn, and in the plural as the sciences opposed to letters; it also has ciencia ficción.[5][17] Spanish lent the word to Basque, Tagalog and Ilocano.[1]
