Pronunciation
Forms
quarto m (plural quartos)[1] As an ordinal it agrees: quarto, quarta, quartos, quartas.[1] Houaiss gives a form carto for 1192.[2]
Etymology
It is inherited from Latin quārtus (“fourth”), written Old Galician-Portuguese quarto and Old Galician-Portuguese carto in the oldest texts.[2][3][1] The ordinal, the fraction “quarter” and the noun “room” are one word.[2][3] Houaiss says the noun first meant a quarter of a house and so a private chamber.[2] Nascentes explains the room as a use of the fraction for an indefinite division, not necessarily into four, just as quatro can mean “a few”, as in “between four walls”.[3] Corominas gives the same explanation for Spanish cuarto “room”, which he dates to the 17th century.[4]
The same Latin word is Galician cuarto, Catalan quart, French quart and Italian quarto.[5][1]
The Latin word goes back to *kʷeturtos and *kʷeturtos, from *kʷetwóres (“four”), like Ancient Greek τέταρτος (tétartos).[1][6]
Earliest recorded meaning
A document of 1192–1193 speaks of as tres quartas do padroadigo “three quarters of the patronage”, and the testament of Afonso II (1214) gives a quarta “a quarter” to the hospitallers and to the bishop.[7] The Miragres de Santiago have hũu carto de carneiro “a quarter of mutton”, and the Cantigas de Santa Maria the ordinal: a quarto dia “on the fourth day”.[7]
Semantic evolution
The ordinal and the fraction are medieval.[7] Houaiss dates the noun “a fourth part” to 1720.[2] Bluteau (1712–1728) has the quarto as a cask holding a quarter of a pipe and the quarto of a building, a part of a large house with its own entrance.[8] Morais (1789) adds quarto de dormir “bedroom”, which has become the main sense of the noun.[9][2][1]
Other senses grew from the fraction: a quarter of an hour, a watch at sea or on guard (a quarter of the night), the quarter of a slaughtered animal, the phases of the moon (quarto crescente).[2][10] In north-eastern Brazil fazer quarto is to keep a wake for the dead.[11][2]
