Forms

espaço m (plural espaços)[1] Old Galician-Portuguese also wrote spaço.[2][3]

Etymology

It is inherited from Latin spatium (“racecourse; open space, extent; interval”), written Old Galician-Portuguese espaço and Old Galician-Portuguese spaço in the oldest texts.[4][2][1][5] García de Diego counts the Portuguese and Galician word among the inherited outcomes, while he treats the Spanish one as a learned word.[6] Corominas calls the Spanish word semi-learned.[6][7]

The same Latin word is Galician espazo, Spanish espacio, Catalan espai, French espace and Italian spazio.[8][1]

The origin of the Latin word is uncertain: de Vaan considers a derivative of *sph₁-to- (“prospered, fattened”), hence “extended”, possible but unprovable, and finds a link with pateō (“to be open”) difficult.[9][1] Figueiredo (1899) had suggested the same root as the Latin verb.[10]

Earliest recorded meaning

In the medieval chronicles the word is mostly temporal: the Crónica Troiana uses it for time given to do something, and the Crónica Geral for a respite or delay (nõ llj derõ outrosi grande espaço “nor did they give him much time either”).[3] The Miragres de Santiago have por espaço de quatorze anos “for a period of fourteen years”.[3]

Semantic evolution

The temporal sense “interval, period, delay” and the spatial “extent, room, distance” have lived side by side since the Middle Ages.[3] Barbosa's 1611 dictionary notes that the Latin word is said both of place and of time.[11][4] Morais (1813) records de espaço “slowly, at leisure” and the printer's space, the piece that separates words in the composing stick.[12] Houaiss and Aulete also give the infinite extent containing all bodies, the universe beyond the Earth's atmosphere, and the specialised senses of mathematics, physics and Kantian philosophy.[4][13] The 20th century brought espacial and compounds such as espaçonave and ciberespaço.[2][1]
