Forms
monstruo m (plural monstruos)[1] Older forms are mostro (Libro de Alexandre, and still in Cervantes, Lope and Vélez de Guevara), mostruo (Alonso de Palencia, 1490) and monstro (Lope, Covarrubias).[2] Oudin already preferred monstruo, and Autoridades made it the standard form.[2]
Etymology
It is borrowed from Late Latin monstruum, an alteration of Latin monstrum (“portent, prodigy; monster”).[2][3][4] Corominas explains the ⟨u⟩ by the influence of monstruōsus (“monstrous”), at a time when Latin wavered between forms such as mortuus (“dead”) and mortus.[2] The DLE and García de Diego also derive it from the Latin noun, with the ⟨u⟩ of monstruoso.[5][6] Wiktionary calls it a learned borrowing.[1]
The Latin noun was a word of religion: a prodigy that warned of the will of the gods, from moneō (“to warn, remind”).[3][7][8] Wiktionary derives it from Proto-Italic *monestrom, formed from the verb with the instrument suffix -trum.[1] De Vaan notes that the regular outcome would have lost the ⟨n⟩, which was brought back from the verb.[9] The verb goes back to *moneje- and Proto-Indo-European *mon-eie- (“to make think of, remind”), a causative related to the root of mente.[9][4] From it Latin formed mōnstrō (“to point out, show”), whence mostrar.[2][9]
Earliest recorded meaning
Corominas's first record is mostro in the Libro de Alexandre, of about 1250.[2][3] The DEMel lists the same text.[10] A translation of Jacques de Vitry's history of Jerusalem, of the mid-14th century, describes an animal quasi mostruo de espantable bramido “like a monster with a fearful roar”.[11] In Enrique de Villena's Eneida of 1427–1428 (in a copy of 1442), a maravilloso monstro is a portent: blood drips from a branch torn from the ground.[11]
Semantic evolution
In the 15th century the word was used for frightful creatures and visions, and for a person who lived against nature.[11] In 1548 a text from Santo Domingo speaks of monstruos humanos, people born with deformities.[12] Cervantes used both monstruos and mostruos, and the insult monstruo de naturaleza.[13] For Calderón the word could mean “hybrid”.[2]
Autoridades defined it as a birth or product against the regular order of nature, and by extension anything extremely large or out of the ordinary.[14] The Academy added a very ugly person or thing in 1817 and a very cruel, wicked person in 1884.[15][16] By 2001 it also had the colloquial sense of a person far above the common run in some activity, and the nonsense verses with which a composer shows a librettist where the stresses must fall.[17] Moliner records its use in apposition with the sense “splendid”.[18] In Chile el monstruo is the audience of the Viña del Mar song festival.[19] In the Dominican Republic monstruo, feminine monstrua, is a friendly form of address.[20]
