Forms

nucă f (plural nuci)[1]

Etymology

It is inherited from Latin nux (“nut”), as the DEX, MDA2 and the DLR give it.[2][3][4] Tiktin explains that Romanian split the Latin noun into a masculine *nucus for the tree and a feminine *nuca for the fruit, on the model of pirus and pira, which gave păr and pară.[5] Ciorănescu instead treats the word as a Romanian feminine made on the tree name nuc: Romanian names trees with masculines and their fruits with feminines, as with măr and prun.[6] Șăineanu also calls it a form drawn from the masculine,[7] and Wiktionary gives both explanations.[1]

Aromanian has nuc and nucã, and Megleno-Romanian nucă.[6][1] In the other Romance languages the Latin word names the fruit: Italian noce, Sardinian nuge, French noix, Occitan notz, Catalan nou, Spanish nuez and Portuguese noz.[6][8][9] The Latin noun goes back to Proto-Italic *knuks and is related to Old Irish cnú and Old English hnutu.[1][10] Because the root is found only in Italic, Celtic and Germanic and has an unusual shape, de Vaan takes it to be a loan from a non-Indo-European language.[10]

Earliest recorded meaning

Tiktin dates the first record to 1532, in a document.[11] In Romanian texts the plural nuci appears twice in the Bucharest Bible of 1688.[12] MDA2 and the DLR date the first record they quote to about 1705, the phrase găoci de nuci “nutshells” in a text printed in Gaster's chrestomathy.[3][4]

Semantic evolution

The word names the fruit of the walnut tree and, as a mass noun, its edible kernel.[3][2] Compounds name other nuts and seeds: nucă-de-cocos “coconut”, older nuca-cocului, nucă galică “gall nut”, and nucă-de-mare or nucă tămâioasă “nutmeg”.[3][13] The Lexicon of Buda (1825) already gives a technical sense, the nut of a screw or press.[14] Șăineanu records nuca genunchiului “kneecap” and the sense “woody outgrowth on trees”, as in nuci de stejar “oak galls”.[7] The DEX adds a mechanical sense, a rod ending in a ball that forms a joint in machines.[2]

The fruit appears in fixed comparisons: a se potrivi ca nuca-n perete “to fit like a nut on a wall” means not to fit at all, and Tiktin gives German wie die Faust aufs Auge as its equivalent.[2][11][8] Another phrase answers “never”: când o face plopul nuci “when the poplar bears walnuts”.[3]
