Pronunciation

  • /ˈtɾut͡ʃa/, [ˈt̪ɾu.t͡ʃa][1]

Forms

trucha f (plural truchas)[1] A document from Huesca of 1181 has the plural truetas, and the DEMel also records the spelling truyta.[2] Leonese has trueita, beside Galician troita.[3]

Etymology

It is inherited from Late Latin tructa (“trout”).[4][5][6][1] The Latin word appears only in late texts: in Saint Ambrose, in the second half of the 4th century, where the manuscripts hesitate between trocta and the usual form, and then in Isidore of Seville and Gregory of Tours;[4][7] Pliny Valerianus has a masculine tructus.[4][7]

The same Latin word gave Portuguese truta, Galician troita, Catalan truita, Old Occitan trocha, French truite and Italian trota.[3][8] The Romance forms point to Latin variants with a long u, a short u and an o; the Spanish word fits the long vowel best, but could also come from the short one.[5][4]

Corominas considers the Latin word a borrowing from another language, probably Celtic.[4][5] With Ernout and Meillet he relates it to Gaulish trucantus, the source of Old Occitan troguen “gudgeon”.[4] The DLE and Wiktionary derive it instead from Ancient Greek τρώκτης (trṓktēs, “gnawer, nibbler”), from τρώγω (trṓgō, “to gnaw”).[6][1] Corominas rejects this: the Greek fish that Aelian describes was a kind of shark, and the Greek words for “trout” recorded in Bova and in Somavera's dictionary of 1707 must themselves come from Latin.[4] The DHLF also finds the Greek word unrelated.[9]

Earliest recorded meaning

Gonzalo de Berceo uses the word for the fish in the Vida de San Millán (c. 1230, known from an 18th-century copy): the saint lived on bread and water, non anguila nin trucha “neither eel nor trout”.[4][10] He uses it again in the Vida de Santo Domingo de Silos (c. 1236), where the dying saint is more pleased by the heavenly voices than by truchas cobdales “trout a cubit long”.[10][4]

Semantic evolution

Corominas finds the word in general use in every period, from Juan Ruiz and Juan Manuel to Nebrija.[4] Thirteenth-century town laws fixed its price, and the Cortes of Alcalá de Henares in 1252 forbade buying fresh trout for resale.[10]

Covarrubias records ayunar, o comer trucha “fast, or eat trout” for people who will not settle for a middle course, and the Diccionario de Autoridades glosses it with Aut Caesar, aut nihil.[11][12] No se toman truchas a bragas enjutas “trout are not caught with dry breeches”, that is, nothing of value comes without effort, is in Cervantes and was written in Chile as early as 1545.[13][14][15]

From 1843 the Academy recorded es muy trucha of a shrewd man who is hard to deceive.[15][16] In Mexico ser muy trucha still means “to be sharp” and ponerse trucha “to keep one's eyes open”; in Argentina and Uruguay the word is colloquial for a person's face or mouth, and a crafty person.[6][17] In New Mexican Spanish it can mean any fish, and in the Canary Islands trucha is also a sweet fried pastry filled with sweet potato or almond, recorded from 1736.[1][18][19]

Usage notes

Trucha de mar is the sea trout, also called reo.[6][23] The DLE has a separate trucha of Guatemala, Honduras and Nicaragua, “a small shop or stall selling haberdashery”;[6][24] Santamaría connected this word with chucho “peddling”.[25] The Academy's dictionaries from the Diccionario de Autoridades to 2001 also gave trucha as a mechanics term for a crane (cabria), which García de Diego derives from Latin *traduculus rather than from the fish.[12][26][27]
