Etymology

It is inherited from Old Spanish arroyo, inherited from Vulgar Latin *arrugium, the masculine counterpart of Latin arrugia (“long gallery of a mine”), a word that Pliny recorded in Spain.[2][3][4] Corominas calls it a pre-Roman Hispanic word, and the DLE also says that it is of Hispanic origin.[2][5] Pliny's testimony suggests that the Romance word first meant an artificial channel for water and only later a natural stream; the BDELC links the meaning to the water that ran through the mine galleries.[2][3]

The same word is Portuguese arroio and Galician arroio.[6][2][1] The feminine form reappears in the southwest of France, in Basque arrolla (“irrigation ditch”) and in Béarnese arroulho, and Basque has arroil (“ditch, gorge”), closer to Pliny's sense.[2] Corominas connects the dialectal Catalan roll, a kind of irrigation channel in Valencia, with this Basque-Gascon variant.[2][7] It is also found in the Alps and northern Italy (Italian roggia, Venetian roza, Friulian roie, Ladin roia) and in Sardinian arroja.[2][8] The Sardinian forms and the West Leonese arruoyo of 1246 point to a variant with a short /o/ beside the /u/ of Pliny's form.[2]

Corominas considers it very uncertain that the Latin word is Indo-European;[9][1] Lewis and Short related it to runcō (“to weed”) and Ancient Greek ὀρύσσω (orússō, “to dig”), and Wiktionary also mentions a possible Punic origin.[2][9][1] Bertoldi proposed that the word originally began with r-, and that the a- was added by the Ibero-Basque avoidance of an initial r.[2]

Earliest recorded meaning

The word appears first in Latin charters, in the Latinised form arogium (Asturias, 775); the Spanish form arroyo is written in a charter of San Pedro de Arlanza of 929.[2] In Alfonso X's prose it already means “a small stream”: in the Estoria de España (1270–1284) the arroyos de la sangre “streams of blood” run until they fill every place, and in the General estoria men dig in an arroyo and water flows.[10]

Semantic evolution

Old Spanish used the word for a small watercourse, for its bed, and figuratively for a stream of any liquid, such as blood.[10][11] Covarrubias (1611) recorded the proverb la mar que se parte, arroyos se haze “the sea that is divided becomes streams”, which he applied to an estate shared among many heirs, and Autoridades repeated it in 1726.[12][13] Salvá (1846) added the sense “the part of a street where the water runs”, which the Academy entered in 1869 together with the phrase poner a uno en mitad del arroyo “to throw someone out into the street”.[14][15] From this street sense the DLE derives the pejorative sense of a wretched, helpless situation (salir del arroyo).[5][16]

In the River Plate and other parts of South America arroyo is a short river that can be navigable, a sense that Alemany labelled American in 1917.[17][18][5] English borrowed arroyo from American Spanish in 1845, as a Californian word for a watercourse or dry stream bed.[19]
