Forms

casa f (plural casas)[1]

Etymology

It is inherited from Latin casa (“hut, cottage”), and Old Spanish casa has the same form.[2][3][4][1] In Vulgar Latin it replaced domus (“house”) as the word for a dwelling;[5][6] Isidore of Seville still defined it as a rustic shelter woven of stakes, reeds and brushwood.[5][6]

The same Latin word is Portuguese casa, Galician casa, Asturian casa, Catalan casa, Occitan casa, Italian casa and Romanian casă.[7][8][1] In rapid speech before a noun it was shortened to cas, meaning “at the house of” in prepositional phrases, and in the same way to Asturian ca, Catalan ca, Italian ca and the preposition French chez.[2][9]

The origin of the Latin word is uncertain.[10][1] Walde and Hofmann derive it from a root *kat- (“to plait”), and others compare words for “hut” from *ket-; de Vaan thinks that its vowel /a/ and its single /s/ after a short vowel make a loanword more likely.[10][1]

Earliest recorded meaning

The first record is in a charter of 938.[2][3] The Cantar de mio Cid (c. 1140, known from a 14th-century copy) already has the word for the house as a building and property: the people of Burgos fear they would lose „los averes e las casas” “their goods and their houses”.[11] The Fuero de Avilés of 1155 forbids anyone to lodge in a man's house against his will.[12]

Semantic evolution

In the Cid the word also means the household of servants and a town or city (Molina, buena e rica casa).[13] Berceo uses it for a monastery.[5] In Alfonso X's prose it means a building, a lord's estates, a square of the chessboard and an astrological house.[14]

In the Middle Ages and the Golden Age the plural casas was common for a single dwelling; it survives in rural Argentina and in casas consistoriales “town hall”.[2][3] Covarrubias in 1611 described the casa as a poor, rustic dwelling and listed several fanciful etymologies, among them Latin casu “fall”, because any wind threatens it.[15] The Academy's dictionary gave the etymology “Del lat. casa, choza” from 1884.[16]

In Colombia and Chile casa is one decade of the rosary, a use Cuervo and Román criticised.[17][18] In the Dominican Republic and Venezuela it is the person who settles disputes in a gambling house.[19][20]
