Etymology
It is inherited from Latin causa (“cause, reason; matter, question”), and Old Spanish cosa has the same form.[2][3][4][1] In Vulgar Latin the word, starting from the sense “matter, affair”, became a synonym of rēs (“thing”) as early as the 4th century AD.[2][3] The DHLF links the change to the frequent use of the two Latin words side by side in legal language.[5] Medieval Latin texts use the word for “thing, property”.[6][7]
The same Latin word is Portuguese coisa, Galician cousa, Asturian cosa, Catalan cosa, Occitan causa, French chose and Italian cosa.[8][9][1] Spanish later borrowed the Latin word again as the learned doublet causa.[9][1]
De Vaan notes that the Latin noun was spelt with ⟨ss⟩ in inscriptions until the 1st century BC, and that Walde and Hofmann connect it with cūdō (“to strike”), whereas Ernout and Meillet doubt an Indo-European origin.[10] Wiktionary also gives its further origin as unknown.[1]
Earliest recorded meaning
The Glosas Silenses, of the second half of the 10th century, have the first record.[2][3] In the Cantar de mio Cid (c. 1140, known from a 14th-century copy) Burgos is forbidden to sell the Cid todas cosas cuantas son de vianda “all things that are food”.[11] The sense is “thing, object” from the start.[12]
Semantic evolution
The word developed many grammaticalised uses.[2] In negative sentences it came to mean “nothing”, from Alfonso X to Tirso de Molina, and still does in Aragonese.[2][13] It could also mean “person”, as in the Crónica sarracina of about 1430.[2] In the Golden Age cosa que… meant “lest”, and in Argentina popular cosa de means “so as to”.[2] Berceo uses it for “matter”, “miracle” and even “life”.[14]
Covarrubias in 1611 explained the riddle formula ¿qué es cosa y cosa? “what is it?”, the source of quisicosa.[15][16] Autoridades follows Alejo Venegas and Covarrubias in deriving cosa from causa.[17] In several Central and South American countries cosa is a euphemism for the sexual organs and for menstruation.[18] In Argentina the masculine coso is used for something whose name one doesn't recall;[2] Corominas takes it from Italian.[2]
