Forms

dúzia f (plural dúzias)[1] Old Galician-Portuguese wrote duzea and duçea;[2][3][4] duzia is recorded from 1351.[2][3][4]

Etymology

It is inherited from Vulgar Latin *duocina, written Old Galician-Portuguese duzea and Old Galician-Portuguese duçea in the oldest texts.[2][3][5][1] Houaiss calls the origin obscure: the Late Latin form is a reconstruction, proposed as a blend of duodecima and duodecena, in which the -i- of Latin duodecim (“twelve”) would have played the decisive part.[2] Wiktionary gives either that form or ducena as the source, both from the Latin numeral.[1] Nascentes instead starts from a supposed old Old Galician-Portuguese *dozena, like the Spanish word, which would have moved its stress under the influence of doze and then raised its stressed vowel.[6] The Latin numeral is a compound of duo (“two”) and decem (“ten”).[7][1]

The neighbouring languages derived their words for “dozen” from the numeral in the same way: Spanish docena, French douzaine and Occitan dotzena; the French word passed into Italian dozzina, German Dutzend and English dozen.[8]

Earliest recorded meaning

Houaiss's first record is duzea in 1269, from Cunha's index of medieval Portuguese.[2] Lorenzo's chronology has sex duçeas de pixotas “six dozen hake” in 1289 and vj duzeas de pixotas in 1303: the word was a unit for counting goods, here fish.[4]

Semantic evolution

The meaning has stayed “a set of twelve things of the same kind” since the 13th century.[2][3] Morais (1813) already records das dúzias “of little worth”, a phrase still used for a mediocre doctor or poet.[9][5] Other phrases are meia dúzia “half a dozen; a few” and às dúzias “in great numbers”, and the dúzia de frade “friar's dozen” or dúzia de treze is thirteen sold for the price of twelve.[2][10] Figueiredo (1899) adds a familiar plural, dúzias “a quantity”.[11] In Brazil a dúzia can also be a hand of bananas cut from the bunch.[12]
