Forms

idiota m or f (masculine and feminine plural idiotas)[1]

Etymology

It is borrowed from Latin idiōta (“layman; uneducated person”), from Ancient Greek ἰδιώτης (idiṓtēs, “private person; layman; ignorant person”).[2][3][1] The BDELC takes it straight from the Greek word.[4] García de Diego calls it a learned word.[5]

The Greek noun is formed from ἴδιος (ídios, “one's own, private”) with the suffix -ώτης (-ṓtēs).[6][1] In Greek it meant a private person as opposed to the State or to an official, then a layman as opposed to an expert, and an ignorant person.[6][4] Latin used it for an ordinary person, a layman or amateur, and Medieval Latin for an unlettered person, a recent convert and a lay brother.[7][8]

Gómez de Silva derives the modern sense from French idiot.[9] García de Diego derives zote “dolt” from a base Vulgar Latin *idiotus that reached Spanish through French.[5]

Earliest recorded meaning

The first record is in Berceo's Milagros de Nuestra Señora (stanza 221), in the sense “unlettered”: a priest who knew only one Mass is denounced to his bishop, qe era idïota, mal clérigo provado “that he was an ignoramus, proved a bad cleric”.[2][10][11] The CDH's copy of the text is of the 18th century.[10]

Semantic evolution

In the 14th century Pedro de Cuéllar's Catecismo (1325) uses it for unlearned clergy, and Fernández de Heredia's Plutarch for a private man, as in Greek: beuir como hombre ydiota en su tierra “to live as a private man in his own country”.[10] The sense “ignorant, unlettered” lasted through the Golden Age;[2][4] Juan de Valdés still used the word as a neologism, and Cervantes uses it in the Quijote.[2][4] Nebrija's Latin dictionary of 1492 glosses Latin idiota as one who knows nothing but his own, and Percyvall in 1591 translates it “an idiot, a lay”.[12][13]

Autoridades still defines it as an ignorant person without learning, and reports two etymologies, from Greek words meaning “one's own language” and “plebeian”.[14] The Academy's dictionary of 1843 has “a rustic, dull and very ignorant person”.[15] Domínguez in 1846 already gave “stupid, wholly incapable of thought” and a medical sense.[16] According to Corominas the modern sense reached the Academy's dictionary in 1869.[2][4] The 1884 edition defines it as “lacking understanding, imbecile”.[17] The DLE now gives “foolish” first, then “conceited without reason” and the medical sense, and marks “uneducated” as obsolete.[3]
