Pronunciation

  • /kosˈtado/, [kosˈt̪a.ð̞o][1]

Forms

costado m (plural costados)[1]

Etymology

It is inherited from Latin costātus (“having ribs”), used as a noun in the neuter, *costātum.[2][1][3][4] The Latin adjective is formed on costa (“rib; side”).[5][6] The same word is French côté, Catalan costat, Occitan costat, Italian costato, Portuguese costado, Galician costado and Asturian costáu.[1][7]

The Latin noun has been compared with Old Church Slavonic кость (kostĭ, “bone”).[8][1] Derksen thinks the kinship quite possible, but de Vaan rejects it, because the Slavic word goes back to a form that could not give the Latin one, and treats the Latin noun as an isolated word without etymology.[8][1] Its own popular outcome is cuesta, which first meant “back” and then “slope”.[9]

Earliest recorded meaning

The Cantar de mio Cid (c. 1140, in a 14th-century copy) tells how Longinus struck Christ: diot' con la lança en el costado, dont ixió la sangre “he struck you in the side with the lance, whence the blood came out”.[10][11][12] The first record in a text without a later copy is the Poridat de poridades (c. 1250).[10]

Semantic evolution

Berceo uses the word for the side of the body and also for the back: sé que los mis costados sobarán la correa “I know the strap will beat my back”.[10][13] In Alfonso X's prose it is the side of the body, a side of anything, a rib, and in geometry each of the lines that form an angle.[14] Nebrija renders it with Latin latus and pleura, and dolor de costado with pleuresis.[15][16]

The Diccionario de Autoridades adds the flanks of an army and the sides of a ship.[17] The plural for the four grandparents' lines appears in the Americas in 1547, in a man limpio de todos quatro costados “of pure descent on all four sides”, and the Academy recorded the phrase noble de todos cuatro costados in 1884.[18][19] In Mexico costado was a railway platform, and in rural Bolivia and north-western Argentina it means pneumonia, a sense Asturian costáu shares.[20][21][22][7]
