Forms
vacío (feminine vacía, masculine plural vacíos, feminine plural vacías)[1] Old Spanish wrote the word with ⟨z⟩, vazio, uazio or bazio, for a voiced sound that Nebrija still had and that survives in Cáceres and in Judeo-Spanish.[2][3] In the Cantar de mio Cid and the Poema de Fernán González the word was stressed vázio, under the influence of the present tense of vaciar.[2]
Etymology
It is inherited from Old Spanish vazio, inherited from Latin vacīvus (“empty, unoccupied”).[2][4][5][1] The Latin adjective was an old and rare variant of vacuus (“empty”), which it replaced in Vulgar Latin.[4][6] It is formed from vacō (“to be empty, be free”) with the suffix -īvus, and Plautus and Terence usually wrote it vocīvus.[1][7][8]
The same Latin word is Portuguese vazio, Galician vacío and Asturian vacíu, and Aragonese and Navarrese dialects have vacivo.[9][1][10] Elsewhere it survives mostly as a word for livestock: Catalan baciu names sheep kept for fattening rather than breeding, and dialects of Occitan, French and northern Italy use it for ewes or cows that are not with young.[11][12] Corominas notes the sense “not pregnant” in an Aragonese inventory of 1379 and explains the Catalan feminine baciva from a form *vacciva, crossed with vacca (“cow”).[2]
The classical adjective gave vago (“empty”), still heard in the phrase en vago, and the learned vacuo, recorded about 1449.[2]
Earliest recorded meaning
Corominas dates the word to the Cantar de mio Cid, of about 1140, where it is spelt with ⟨z⟩.[2][4] In the Lapidario of Alfonso X (1250–1279) it describes a stone that is hollow inside: et quando la quebrantan fallan la uazia de dentro “and when they break it they find it empty inside”.[13]
Semantic evolution
In 1611 Covarrubias gave both the noun, “the unoccupied place”, and the sense “vain, foolish and presumptuous”, with the saying una vana y dos vacías for empty talkers.[14] The Academy's dictionary of 1817 listed the senses that the word still has: empty of any body, of a female animal without young, vain, idle, and of a cart, a house or a town without its load or its people.[15]
The noun took on technical senses: the flank between the ribs and the hip, a step of Spanish dance, and in physics a space without matter.[5][16] It also names a lack that is felt, of a thing or a person.[5] In Central America and the Dominican Republic a food eaten vacío is eaten without tortilla or side dish, and in Costa Rica coffee is drunk vacío, on its own.[17]
