Forms

noix f (invariable)[1] Old French noiz (1155), noix from the 13th century.[2][3] Anglo-Norman also had neys, nois and noyz.[4]

Etymology

It is inherited from Old French noiz, inherited from Latin nux (“nut, walnut”).[5][2][1][6] The Latin word named any fruit with a hard shell and kernel, especially the walnut, and in the plural also the walnut tree.[2][7]

Cognate with Romanian nucă, Italian noce, Occitan noga, Catalan nou, Spanish nuez and Portuguese noz.[8][9] Rey compares Old Norse hnot and an Irish word, and takes them back to an Indo-European root found only in the West;[2] the Petit Robert calls the Latin word perhaps related to English nut, German Nuss and Dutch noot.[8]

Earliest recorded meaning

It is first found as noiz in Wace's Brut (1155), meaning the fruit of the walnut tree.[5][2]

Semantic evolution

With a qualifier the word named the fruit of other trees with woody shells (1179): noix de coudre for the hazelnut, then noix vomique (13th century), noix de coco (1610) and noix de cajou (1694, as noix d'acajou).[2][5] In Old French it stood for a thing of very little worth after a negative, an idea found again, without continuity, in à la noix “worthless” (1896 or 1901) and in the familiar use for a stupid person (1915).[2][5] Une noix de beurre, a small amount, dates from 1931.[2][5]

Technical senses grew from the idea of a swelling or rounded part: the notched nut of a crossbow (about 1195), a part of the gunlock (1690), and in butchery the fleshy part of a leg of mutton (1690) or of veal (1762).[2][5]
