Forms

riñón m (plural riñones)[1]

Etymology

It is inherited from Old Spanish reñón, written ⟨rennon⟩ in the oldest texts, inherited from Vulgar Latin *rēniō (“kidney”), a derivative of Latin rēn, rēnis (“kidney”).[2][3][1][4][5] The DLE gives the Latin simple word alone as the etymon.[6] This older form still appears in Lope de Vega and in La Pícara Justina.[2]

Most Romance languages have forms that presuppose the Vulgar Latin word: Catalan ronyó, earlier renyó, Occitan renhon, French rognon and Italian rognone.[2][7][8] In Portuguese, French and Italian the Latin simple word lives on as Portuguese rim, French rein and Italian rene, beside the derivatives that name more particularly the edible kidneys of animals.[2][9] Corominas thinks this was probably the first sense everywhere, but finds it hard to say whether it explains the creation of the derivative or whether the Latin dialect synonym nefrones influenced it.[2] The BDELC adds that Castilian kept the plural of the simple word, renes, all through the Middle Ages, but early tended to make the derivative the general word.[3]

The origin of the Latin word is uncertain.[10][1] De Vaan finds a connection with Baltic words for the loins and a reconstruction Proto-Indo-European *srēn- (“hip, loins”) conceivable, and also mentions *h₂r-ēn (“kidney”) beside the Celtic words for the kidney.[10] Wiktionary adds a link with Ancient Greek φρήν (phrḗn, “midriff, mind”).[1]

Earliest recorded meaning

Alfonso X's Lapidario (c. 1250, in a manuscript of the middle of the 13th century) speaks of the stone that forms inside the human body en la uexiga o en los rennones “in the bladder or in the kidneys”, and of a stone that breaks the stone formed in the bladder or the kidney.[11][5] Corominas's first record is the Glosario de Toledo, of about 1400.[2][3]

Semantic evolution

The plural renes, used as a feminine, lasted beside riñón for a long time: the Fuero Juzgo sets a payment for a man wounded en las renes, and Nebrija, Juan de Pineda, Sigüenza and Correas still use it.[2] Nebrija (c. 1495) has ren o riñón de animal.[2][12] Don Quixote speaks of a man long sick de los riñones.[2]

The sense “the heart or centre of a place or time” is found in G. A. de Herrera's en el riñón del invierno, and in Chile in 1545 and 1551 (el riñón de la tierra).[2][13] The Diccionario de Autoridades records it, together with the phrase tener cubierto el riñón “to be well off”, from a well-fed animal whose kidney is covered in fat.[14] The Academy added the mining sense of a rounded lump of mineral in 1899.[15] In Mexico, Chile and Uruguay a kidney-shaped hospital basin is a riñón.[6][16] In the Canary Islands más feo que un riñón is said of a very ugly person.[17]
