Forms

rostro m (plural rostros)[1] Old Spanish wrote both rostro and rrostro.[2] Juan Ruiz also has rosto, with the second /r/ lost by dissimilation, as in Portuguese.[3]

Etymology

It is inherited from Old Spanish rostro, inherited from Latin rōstrum (“beak; snout, muzzle”).[3][4][5][1] The Latin noun is a derivative of rōdō (“to gnaw”) with the instrumental suffix -trum, so it was properly “the thing that gnaws”, a bird's beak or the snout of a pig or a dog.[3][6][7] Only very colloquial authors such as Plautus and Petronius applied it to people, as a jibe, much as hocico or jeta are used in Spanish; in later Latin this use became more frequent and gradually lost its mocking tone.[3] The verb goes back to Proto-Indo-European *Hreh₃d- (“to gnaw, scrape”) or *ureh₃d-.[8][1]

The same Latin word is Portuguese rosto (older rostro), Galician rosto, Aromanian rost (“mouth”) and Romanian rost.[9][10][11] Coromines regards Catalan rostre “face” as a borrowing from Spanish, while the learned French rostre “ram of a ship; beak” was taken directly from Latin.[12][13]

Earliest recorded meaning

The first record is in the Cantar de mio Cid (c. 1140), in the scene of the lion that meets the Cid: ante mio Cid la cabeça premió e el rostro fincó “before my Cid it bowed its head and lowered its muzzle”.[14][3] Menéndez Pidal glosses the word here as “snout, mouth”.[15]

Semantic evolution

Throughout the Middle Ages rostro kept its Latin sense of “beak” or “pointed snout”: Juan Ruiz writes of a mule sharpening its rostros and teeth.[3] Applied to people it meant “mouth, lips” with a strongly contemptuous tone, as in Juan Ruiz's monstrous mountain girl with boca de alano e los rrostros muy gordos “a mastiff's mouth and very thick lips”, and the Moriscos of the 16th century still used it for “lip”.[3] Corominas dates the sense “brutish human snout” to about 1280.[4] Alfonso X's prose also uses it for the iron ram of a ship and for a pointed spur of a mountain.[16]

The change to “face” took centuries, and had begun in Latin.[3] A blow en el rostro in the Libro de Apolonio already points that way, and the 14th-century Castigos of Sancho IV use the word for the prominent part of the face, with mouth, nose and eyes.[3] By the 15th century the common language used rostro only for the face, and Covarrubias's mention of the old sense in 1611 is a Latinism.[3][4] Covarrubias and the Diccionario de Autoridades record phrases such as rostro a rostro “face to face”, a rostro firme “face to face, resolutely” and hacer rostro “to stand up to the enemy”.[17][18]

Today the word is formal beside cara, and Moliner notes that the phrases built with it are falling out of use.[19][1] In colloquial Spain rostro has also come to mean “cheek, nerve”, like cara and jeta.[5][20] In Honduras it names the catafalque of a church funeral.[21]

Timeline

  • c. 1140 – the Cantar de mio Cid uses rostro for a lion's muzzle.[14][3]
  • 1218–1250 – the Fuero de Zorita de los Canes doubles the fine when a nose is cut off together with the rostro.[14]
  • 13th century – the first hints of the sense “prominent part of the face”.[4][3]
  • 1270–1284 – Alfonso X's Estoria de España describes ships armed with iron rostros, rams.[16]
  • c. 1280 – the word is used for a brutish human snout.[4]
  • 15th century – rostro means only “face” in the common language.[4][3]
  • 1525 – the first record from the Americas, in Mexico City.[22]
  • 1539 – first record of the derivative derrostrarse, and arrostrar follows about 1580.[4]
  • 1611 – Covarrubias records rostro a rostro and hacer rostro.[17]
  • 1884 – the Academy's dictionary gives the etymology and the obsolete sense “mask”.[23]
