Etymology

The word for mud and clay is inherited from Old Spanish barro, inherited from Vulgar Latin *barrum (“clay”), an old pre-Roman word that Spanish shares with Portuguese, Gascon and Languedocian.[2][3][1] The DLE suggests a Celtic origin and compares Middle Irish broch (“rubbish”) and Gaulish *barros (“thicket”).[4][1] Wiktionary takes it to be Paleo-Hispanic or Iberian, and García de Diego Celtic or Iberian.[1][5] Covarrubias in 1611 thought it Arabic, from a word for uncultivated land, or Greek, from the word for “weight”, and the Diccionario de Autoridades repeated the Arabic explanation.[6][7]

The same word is Portuguese barro, Galician barro, Asturian barru, Aragonese bardo, Italian barro and Old Occitan bart.[3][8][1] The REW notes that it is missing in northern France.[3]

Earliest recorded meaning

The earliest hit in the CDH is Abraham de Toledo's Moamín, a treatise on hunting animals (1250, in a copy of the later 13th century), which advises keeping hawks on perchas de barro acerca de tierra “perches of clay near the ground”.[9] Alfonso X's Picatrix (1256), the oldest original, has un tiesto de barro “an earthenware pot”.[9][10] Corominas dates the word 1250–1280.[2]

Semantic evolution

In medieval texts barro was both mud and potter's clay, and Alfonso X uses it for the bitumen mortar of the Tower of Babel.[11][12] Nebrija rendered it with Latin argilla.[13] The Diccionario de Autoridades defined it as earth mixed with water, whether mud made by rain or a mixture for walls, bricks, tiles and pots, and also as a drinking vessel of scented clay, a búcaro.[7] The Academy's 1817 edition recorded the proverb Barro y cal encubren mucho mal, of a fair surface hiding what is bad.[14] The 1899 edition added the figurative sense “worthless thing, trifle”, and the DLE today also has “dishonour, moral degradation”.[15][4]

In the River Plate barro is a blunder made through carelessness, usually without ill intent.[16][17][18]

Pronunciation

  • /ˈbaro/, [ˈba.ro][1]

Forms

barro m (plural barros)[1]

Etymology

The word for a pimple is inherited from Latin varus (“pimple, pustule”).[22][2][23][1] Corominas explains the double /r/ of the Spanish and Portuguese word by the influence of verruga; a real blend of the two words gave Asturian bérrago (“tumour in cattle”) and Galician bérrego.[22] Álava and the north of Burgos keep the single /r/ in the forms ⟨varo⟩ and ⟨baro⟩.[22][24]

The same word is Portuguese barro and Old Occitan vare (“larva”); Catalan barb is a slight change of an older ⟨bar⟩, made by folk etymology after barba (“beard”).[22][25] It passed early into Andalusian Arabic, which formed from it a derivative meaning “pimply”.[22]

The Latin word goes back to Proto-Italic *waros; de Vaan compares Lithuanian vìras (“tapeworm larva; pimple”) and marks the Indo-European reconstruction as uncertain.[26][1] Wiktionary derives it from Proto-Indo-European *wer- (“raised spot”) and relates it to varix (“varicose vein”) and verrūca (“wart”).[1] It is not the same word as the adjective “bow-legged”, which de Vaan treats separately.[26]

Earliest recorded meaning

The DME's first record is Chirino's Menor daño, of 1428 but printed in 1505, which has barros del rostro “pimples of the face”.[11] Corominas dates the word to Nebrija (c. 1495), who already writes it with b- and -rr-: Barro que nace en la cara “a pimple that grows on the face”, Latin varus.[22][2][11]

Semantic evolution

Covarrubias in 1611 described the barro as a reddish mark on the face, chiefly of youths beginning to grow a beard, and, following Nebrija, traced it to the Latin word for a pimple.[6] The Academy's 1817 edition used the plural for these marks, and also for small tumours on mules and cattle.[14] In Soria the word names a swelling raised on livestock by the larvae of the horsefly, and in Cespedosa it came to mean the horsefly itself.[22] The Canary Islands use it for a pimple, and Leonese for a grub that grows under the skin of cattle.[27]

Timeline

  • c. 1495 – Nebrija gives Latin varus.[22][11]
  • 1591 – Percyvall glosses it “wheals, pimples”.[28]
  • 1611 – Covarrubias records the sense “red mark on the face” and derives it from varus.[6]
  • 1817 – the Academy records the sense “small tumours in cattle”.[14]
  • 1917 – Alemany derives it from Latin varus.[29]

Meanings
