Pronunciation
Forms
queijo m (plural queijos)[1] Houaiss records the historical spellings queso (in a Latin legal text of 1188–1230), queixo (1312), queyio (14th century) and queyjo (15th century).[2]
Etymology
It is inherited from Latin cāseus (“cheese”), written Old Galician-Portuguese queijo in the oldest Portuguese texts.[2][3][1] Nascentes and Aurélio pass it through an archaic queiso, and Nascentes's fuller dictionary cites Menéndez Pidal, who sets up a form *caisu with the i moved into the first syllable.[4][5] Houaiss adds that the word came by way of Spanish queso, recorded in Spain from 980, whereas Wiktionary and the other dictionaries derive it straight from the Latin word.[2][1]
The same Latin word is Galician queixo, Italian cacio and Romanian caș, besides the Spanish word.[1] Corominas notes that it survived in Romanian, Italian, Sardinian, Castilian and Portuguese, while Gallo-Romance and Catalan replaced it with Latin formaticus “(cheese) made in a mould”, whence French fromage and Italian formaggio.[6][2] The Latin word was also borrowed early into Germanic, giving German Käse and English cheese.[2][1]
De Vaan reconstructs *kāsejo- with a query, and finds that every proposed etymology rests on weak assumptions: the old link with Proto-Indo-European *kwath₂- (“to boil, ferment”) would leave an unexplained loss of the w.[7][1] The Latin word may have been borrowed from a neighbouring Italic language, perhaps Sabine.[1]
Earliest recorded meaning
In a Latin legal text of 1188–1230 the Romance word already appears, spelt queyso in the phrase in anafaga, et in sal, et in queyso.[4][2] The first dated Portuguese record in Houaiss is queixo of 1312.[2] The Cantigas de Santa Maria speak of bon queijo rezente “good fresh cheese”.[8]
Semantic evolution
The sense “cheese” has stayed at the centre of the word since the Middle Ages.[2] Morais's dictionary of 1789 already extends it to things shaped like a cheese, such as queijo de figos, a cake of dried figs pressed into a round, and a brawn made from a pig's head.[9] Houaiss dates the slang sense “profitable business” to 1899, and Caldas Aulete records the related sense “an easy source of gain”.[2][10]
Informal Brazilian Portuguese uses the word for the full moon and for a bald head, and in Ceará for a patch of another colour sewn into the seat of trousers; in Portugal it can mean a buttock, and é queijo “it's cheese” means “it is easy” or “it is good”.[2][11] The phrase ter a faca e o queijo na mão “to have the knife and the cheese in one's hand” means to have full power over something.[12][10]
Portuguese passed the word into Malay and Indonesian as keju, into Tetum as keiju and into Guinea-Bissau Creole as keju.[1]
