Forms

pecho m (plural pechos)[1] Old Spanish texts use the plural los pechos with a singular sense;[2] Corominas found no certain example of the singular pecho before the late 15th century.[3] DEMel records the form payto in charters of San Vicente de Oviedo dated 1028, and also pecto and plecho.[2] Asturian has pechu and Aragonese peito.[4][5]

Etymology

It is inherited from Old Spanish pechos, inherited from Latin pectus (“breast, chest”).[3][6][7][1] The Latin word was a neuter, so the Romance form continues its accusative, which was the same as the nominative and gave Old Spanish a form ending in -s; that form was felt as a plural, and the medieval texts use that plural form for one chest, until the singular pecho appears at the end of the Middle Ages.[3] Catalan went the same way: its old singular pits came from the neuter, was later taken for a plural, and a new singular Catalan pit was drawn from it.[8]

The same Latin word is Portuguese peito, Galician peito, Asturian pechu, Aragonese peito, Old French piz, Italian petto and Romanian piept.[9][5][1] The French descendant pis lost the sense “chest” to poitrine and kept the rural sense “udder”.[10] Spanish peto “breastplate” is a doublet borrowed from the Italian word, and pectoral is a learned borrowing of Latin pectorālis.[6][1]

The Latin word goes back to *pektos.[11][1] De Vaan thinks Old Irish ucht (“breast, chest”) a likely cognate, if it comes from an earlier *pektu-; he rejects a link with Tocharian, whose word belongs to another root, and finds Sanskrit पक्ष (pákṣa-, “wing”) too far in meaning.[11] Wiktionary lists Proto-Indo-European *pekt-, *pek- and *peg- (“breast”) among the suggested roots and calls the further origin uncertain.[1]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, known from a 14th-century copy) already has the plural with the sense of one chest: „metiól' la lança por los pechos” “he thrust the lance into his chest”.[12][3] In Alfonso X's Lapidario (1250–1279) a stone helps a man who suffers a cough or another illness „en los pechos”, that is, in the chest.[13]

Semantic evolution

In Old Spanish the plural los pechos was said of the chest of men and women alike, of the breast of a bird and of the brisket of a sacrificed ram; the sense “a woman's breasts” is found in Juan Ruiz.[3][13] In the slang of the underworld the word was turned round by metathesis into chepo, recorded in 1609.[3]

Covarrubias in 1611 described the chest as the seat of courage and listed phrases built on that idea: hombre de pecho “a brave man”, tomar a pechos “to take something to heart”, descubrir el pecho “to tell one's secret”.[14] The Diccionario de Autoridades noted that pecho was used for a woman's breast “for more decency” than teta, and the Academy's dictionaries kept that remark into the 19th century.[15][16] The Academy's editions also gave the figurative senses “inner self”, “courage, constancy” and “strength of the voice for singing or speaking”, which are still in the DLE.[16][7]

In 1884 the Academy separated the old word for a tribute, which it derived from Latin pactum, into an entry of its own.[17] In the Americas pecho also names the breaststroke (Ecuador, Chile, Argentina, Uruguay) and a cut of beef from the brisket (Central America, Ecuador, Bolivia, Uruguay).[18]

Timeline

  • c. 1140 – the Cantar de mio Cid uses los pechos for the chest of a warrior.[12][6]
  • c. 1215 – the Vida de Santa María Egipcíaca (in a 14th-century copy): the saint strikes her breast in penance.[12]
  • 1250–1279 – Alfonso X's Lapidario uses the word for the chest as the seat of a cough, and for the breast of a bird.[13]
  • 1513 – Nebrija's Vocabulario has the singular pecho “part of the body”, Latin pectus.[19]
  • 1525 – the first record from the Americas, in Mexico City, of a horse “abierto de los pechos”.[20]
  • 1609 – the slang form chepo is recorded.[3]
  • 1611 – Covarrubias lists hombre de pecho, tomar a pechos and other phrases.[14]
  • 1884 – the Academy gives the etymology from Latin pectus and makes the tribute a separate entry.[17]
