Forms
adulterio m (plural adulterios)[1] A popular form adurterio is recorded in Murcia.[2]
Etymology
It is borrowed from Latin adulterium (“adultery”), a learned word taken from Latin in the 13th century.[3][4][5] Wiktionary instead treats it as inherited.[1] Portuguese adultério, Catalan adulteri and French adultère (12th century) were likewise taken from Latin.[6][7][8][9] Popular forms of the Latin word survived only in older Gallo-Romance, such as Old French avoutire and Old Occitan avouteri.[10]
The Latin noun is formed from adulter (“adulterer”) with the suffix -ium according to the OLD.[11] Wiktionary derives it from the verb adulterō (“to commit adultery; to falsify”) instead.[1] The verb is perhaps from ad- and alter (“the other”), and the agent noun may in turn be a back-formation from the verb.[11][1] Spanish has the related learned words adúltero (13th century) and adulterar (early 15th century).[3]
Earliest recorded meaning
The earliest hit in the CDH is the Fazienda de Ultra Mar (c. 1200, in a 13th-century copy), which tells of the vengeance taken por el duelo del adulteryo de Dina su ermana “for the wrong of the defilement of Dinah their sister”.[12] The Fuero de Zorita de los Canes (1218–c. 1250) heads a chapter Del que su muger fallare en adulterio “Of him who finds his wife in adultery”.[12]
Semantic evolution
In medieval texts the word covers illicit or sinful intercourse in general, beside the strict sense of a breach of marriage.[2][13] The Medieval Latin word had the same broad sense of any intercourse outside marriage.[14] Alfonso X's Estoria de España also uses it for the breaking of a law or a church commandment.[15]
The Diccionario de Autoridades (1726) defines it as intercourse between a married woman and another man, a married man and another woman, or two married people.[16] The Academy's dictionary of 1884 adds a legal definition, as the crime of a married woman who lies with a man not her husband, and of the man who knows she is married.[17] The 2001 DRAE still limited it to a partner of the other sex, a restriction the current DLE has dropped; both keep the old sense “falsification, fraud”, now marked as obsolete.[18][5]
