Pronunciation

  • Northern: [ˈko̞s.tə][1]
  • Balearic, Central: [ˈkɔs.tə][1]
  • Northwestern, Valencia: [ˈkɔs.ta][1]

Forms

costa f (plural costes)[1] The DCVB records /kɔ́stə/, /kɔ́sta/, /kɔ́stɛ/ and /kɔ́stɔ/, the final vowel varying with the dialect.[2] A charter of 978 writes chosta.[3]

Etymology

The word for the coast, the slope and the rib is inherited from Latin costa (“rib; side”), a word that in the Romance languages came to be applied above all to the sides and slopes of mountains and to the coastline.[3][2][4][5][1]

The same Latin word is Italian costa, French côte, Occitan còsta, Portuguese costa and Romanian coastă.[6][1] The inherited Spanish cuesta (“slope”) stands beside costa (“coast”), which the REW takes as a borrowing from Catalan.[6]

The Latin noun has no secure etymology: it has been compared with the Slavic word for “bone”, Proto-Slavic *kostь, a connection de Vaan rejects and Derksen thinks quite possible.[7][1]

Earliest recorded meaning

In its topographical sense the word is frequent from the 10th century in charters in Latin or half Catalan: Balari and Bastardas–Bassols collect examples from 941 on, and a charter of 978 in the cartulary of Sant Cugat bounds a piece of land ad ipsa chosta “at the slope”.[3] The bodily sense is recorded from the 13th century, as in Llull's Blanquerna: God made Eve d'una costa que li trasch “from a rib that he took from him”.[3]

Semantic evolution

From the rib the word passed to the back, on which loads are carried: Jaume I's men leave a town with what they can carry en les costes e en les mans, and Eiximenis puts a pack-saddle a les costes.[3][8] From this came the phrase a costes “on one's back”, used figuratively by Muntaner of fighting ab la febre a costes;[3] girar les costes “to turn one's back, to flee” is in a war report of 1304.[3]

In the Pyrenees costa can mean a very steep mountainside, and it is in mountain names such as Costabona;[3] Onofre Pou glosses it as a way up or down.[3] Faraudo also records it at sea for a shroud of a galley (1352), for the splints of a scabbard, and as a preposition meaning “beside”.[8]

Among the derivatives, acostar “to bring near” is recorded in 1250, costat “side” in Llull, and costaner in Labèrnia's dictionary of 1839.[4] The DIEC2 marks the sense “rib” as old and gives first the coast, then the steep slope.[9]

Forms

costa f (plural costes)[1]

Etymology

The word for costs and expenses is a deverbal noun from Catalan costar (“to cost”), first recorded in 1598.[11][5][1] The DCVB thinks it was more probably taken from Spanish costa, noting that the older Catalan word is cost.[2] The verb comes from Latin constō (“to stand firm; to cost”).[11]

Earliest recorded meaning

Coromines and the GDLC date the noun to 1598, and Coromines also finds it in Torra's dictionary of 1640.[11][5]

Semantic evolution

The DCVB gives the senses “cost”, “what a thing costs” and “the expenses of a lawsuit”.[2] The DIEC2 keeps the phrase a costa de “at the cost of” and the plural for court costs.[9]
