Forms
alerta m or f (masculine and feminine plural alertas)[1] In Argentina, Uruguay, Venezuela and other American countries the noun is often masculine, el alerta.[2]
Etymology
It is borrowed from Italian all'erta, literally “on the height”, a phrase built on erta (“ascent, slope”), the noun use of erto (“raised, steep”), originally the participle of the old verb ergere (“to raise”).[3][4][5][1] The Italian verb continues Latin ērigō (“to raise, set upright”) through a contracted form *ergere,[4][6][7] and the Latin verb is formed of ex- and regō.[8]
The phrase was at first a call to soldiers to rise and stand on guard against an attack.[3][4] Bénaben explains it as a summons to go up to the high ground and watch for the enemy.[9] According to Corominas, the Italian phrase stare allerta is found from the second half of the 15th century, and the adjective since Dante.[3] Nocentini dates the adverb allerta to 1536.[10] From Italian the word also passed into French alerte in the 16th century and into the other Romance languages,[3] for example Portuguese alerto (“watchful”).[6]
Older scholars connected the word with Latin alers (“skilful, clever”), an adjective found only in Latin glossaries.[3] Corominas, like Heraeus before him, rejects the idea, because the word never occurs in texts and may itself be a Latinisation of the Romance word.[3]
Earliest recorded meaning
The CDH's earliest record is in the Corónica de Adramón of about 1492, where someone secretly tells his men to keep watch: que estuvyesen al ojo alerta.[11][1] Corominas's first record is in Torres Naharro's Seraphina (1517), which says that one must estar alerta to follow characters speaking four languages.[3][12] In both the word is an adverb meaning “on the watch, attentively”.[12][11]
Semantic evolution
The adverb, used with estar, andar or vivir, is the oldest and most frequent use in the Golden Age.[12][13] Fernández de Oviedo used it as an adjective in the 1540s, describing an animal with ears pricked up and alert, and Classical Spanish also formed the adjective alerto (first half of the 16th century, Castillejo) and the verb alertar;[14] Corominas described both as old-fashioned in his day.[12][3] The Quijote has both estar alerta and the adjective in oydo alerto.[14] Autoridades (1726) records the phrase ojo alerta “look out!”, and guesses that the word comes from Latin erectus, because a sentry stands on high ground.[13]
The noun entered the Academy's dictionary in 1817 as the call that sentries pass to one another so as not to fall asleep, or give to the troops so that they are ready.[15] In 1884 the Academy gave the Italian etymology and described ¡alerta! as an interjection of the sentries.[16] Today the noun mostly means a state of watchfulness or a warning, and the authorities grade it in colours: alerta amarilla, alerta naranja, alerta roja.[5][17] In Tenerife and La Palma alerta is also the name of a children's team game played with a handkerchief.[18]
