Forms

noz f (plural nozes)[1] Old Galician-Portuguese wrote noze and noce;[1] Wiktionary also lists the variants anoz, noç and nuace.[1] The Portuguese dialect form anoz is recorded in the TLPGP.[2]

Etymology

It is inherited from Latin nux (“nut”), through a Vulgar Latin form with an open /ɔ/, *nŏce, written Old Galician-Portuguese noze and Old Galician-Portuguese noce in the old language.[3][1][4] Nascentes calls the change of the Latin /u/ unexplained, and Wiktionary also finds the reasons for this early lowering unclear.[5][1] Corominas suggests that the variant may owe its vowel to a Celtic word for the nut.[6]

The same Latin word is Galician noz, Spanish nuez, Catalan nou, Occitan notz, French noix, Italian noce and Romanian nucă.[7][1]

The Latin noun goes back to *knuks, and its cognates are Celtic and Germanic: Old Irish cnú, Old Norse hnot and Old English hnutu.[8][1] Wiktionary connects the Germanic words with Proto-Germanic *hnuts, the source of nut.[1] Because the word is found only in Italic, Celtic and Germanic, has different suffixes in each, and belongs to the vocabulary of trees and fruits, de Vaan concludes that it was borrowed from a non-Indo-European language.[8]

Earliest recorded meaning

In the Cantigas de Santa Maria the nut is already the measure of something worthless: que te non cost'hũa noz “that it should not cost you a nut”, Sol duas nozes non vales “you are not worth even two nuts”.[9] Cunha dates the word to the 13th century, Houaiss to the 14th, from Cunha's medieval index.[3][4]

Semantic evolution

From the walnut the word spread to other hard-shelled fruits: Houaiss and Aurélio define it in botany as any dry, indehiscent fruit with a single seed, such as that of the palms.[4][10] In the chronicles of the East it named the nutmeg: Dalgado quotes João de Barros (1552) listing canella, crauo, maça, noz among the spices, and Castanheda describing the noz que chamamos mozcada.[11] Folqman's dictionary of 1755 has Nos moscada, and Morais (1813) distinguishes several kinds of walnut.[12][13]

Transferred senses name things shaped like a nut: the thickened part of the anchor through which the stock passes, the frog of a violin bow, and in older usage the catch on which the string of a crossbow was held.[4][14] Silva Bastos records the slang sense “head”, which Houaiss and Priberam still give as informal.[15][4][14] A small lump of something, such as butter, is also a noz.[14][16]
