Forms

oruga f (plural orugas)[1]

Etymology

It is inherited from Old Spanish oruga, inherited from Vulgar Latin urūca, an assimilated form of classical ērūca (“caterpillar; rocket (plant)”).[2][3][4][1] This form is found in late Latin authors, from Pliny on.[2] Dozy and Baist derived the Spanish word from an Andalusian Arabic word for “caterpillar, grub, aphid” recorded by Pedro de Alcalá.[2] Corominas rejects this, since the Arabic word is itself a loan from the Romance of al-Andalus, of Latin origin.[2][5]

The Vulgar Latin form also gave Old Occitan auruga, while Catalan eruga, Occitan eruga and Galician eiruga continue the classical one.[2][6] The plant's Italian name, ruchetta, was borrowed into Spanish as ruqueta.[2][6]

De Vaan analyses the classical word as ēr (“hedgehog”) with a suffix taken from a word like verrūca (“wart”): the caterpillar would be named for its rough back.[7][1] Wiktionary also gives a derivation from Proto-Indo-European *ǵʰers- (“to bristle”).[1] The plant name seems to be secondary to the animal name.[1][8]

Earliest recorded meaning

The Fazienda de Ultra Mar (c. 1200, in a 13th-century copy) translates Joel's plague of insects: remasalla de oruga comió la langosta “what the caterpillar left, the locust ate”.[9][10] Corominas's first record is later, a glossary of the Escorial of about 1400.[2][3]

Semantic evolution

Both Latin senses, the larva and the plant, came into Spanish.[2][7] The Moamín of 1250 uses the seed of the oruga plant in a remedy for hawks, and the Gospel of Matthew of about 1260 has oruga for the creature that eats stored treasure.[9][11] Nebrija in 1495 gave both, oruga ierva conocida and oruga gusano.[12][13]

Covarrubias in 1611 called it a well-known herb put in salads, and the name of small worms bred on green leaves.[14] The Diccionario de Autoridades added a sauce of the herb with sugar or honey, vinegar and toasted bread, with a quotation from a cookery book.[15] In the 19th century the Academy's definitions of the larva became zoological, and the 1869 edition listed the expression oruga le dio, said of something lost or wasted.[16][17] The modern sense “caterpillar track” of a vehicle is a comparison with the larva; it also names a tracked vehicle.[4][18]
