Forms

realidad f (plural realidades)[1]

Etymology

It is borrowed from Medieval Latin reālitās, formed from Late Latin reālis (“real, actual”) with the suffix -tās.[2][3][4][1] That adjective is from Latin rēs (“thing”), whose plural meant “things, reality, nature”.[2] The Spanish word can also be analysed as from Spanish real + -idad.[1]

DICCA-XV, however, derives the 15th-century word from real “royal”, a sense it has in one early text (see below), while other texts of the same time already have the sense “reality, truth”.[5][6] The same Medieval Latin word gave Catalan realitat and French réalité.[7][8]

Earliest recorded meaning

Corominas dates the word to Oudin's dictionary (1607).[2][3] The CDH has it two centuries earlier.[6] In Juan Alfonso de Baena's poems (1406–1435, in a copy of about 1465) a king is praised for his grant realidad, together with his franqueza “generosity” and realeza “royalty”, which DICCA-XV relates to real “royal”.[6][5] The sense “truth, reality” is found in Mose Arragel's translation and glosses of the Bible of Alba (1422–1433), la rrealidat del mandamiento diuino “the truth of the divine commandment”, and in Enrique de Villena's glosses on the Aeneid (1427–1428), segúnd la realidat “according to what really happened”.[6] The earliest copy that is not later than the text is the record of the Cortes of Toledo of 1436, which speaks of the rrealidad e verdad delos proçesos “the reality and truth of the proceedings”.[6]

Semantic evolution

Oudin (1607) already recorded the phrase en realidad de verdad “in actual truth”, and Autoridades defined the word as the physical and real existence of a thing and as “truth, sincerity”.[2][9] The phrase is found in the Americas from 1551, in Guatemala and Yucatán.[10] The Academy kept these two senses until the 1884 edition, which still glossed realidad as “truth, ingenuousness, sincerity”.[11][12] The modern dictionary has instead the sense “what is effective and practical, as opposed to the fanciful”, and the computing term realidad virtual.[13] In philosophy the word also names the essence of a thing, apart from its appearance.[14]
