Forms

nu (feminine nua, masculine plural nus, feminine plural nuas)[1] The medieval forms are nuu and the feminine nua, recorded from the 13th century;[2][3] nuu is still written in the 15th century.[2][3]

Etymology

It is inherited from Latin nūdus (“naked”), written Old Galician-Portuguese nuu in the oldest texts.[2][3][1][4] García de Diego records the old form in Catalan too, and the modern form in Galician as well as Portuguese.[5]

The same Latin word is Galician nu, Old Spanish nuo, French nu and Italian nudo;[6][5][1] the Spanish nudo “naked” is a learned word.[6][5][1] De Vaan reconstructs a PIE adjective Proto-Indo-European *nogʷs “naked”.[7] Wiktionary gives *nogʷedʰós, from *nogʷós.[1] Cognates are Ancient Greek γυμνός (gumnós), Sanskrit नग्न (nagná) and Old English nacod, the source of English naked.[1][7]

Earliest recorded meaning

The Cantigas de Santa Maria have pero ando nuu e mui mal parado “but I go naked and in a very poor state” and senon da camisa, toda nua “all naked but for her shift”.[8] A cantiga d'escarnho of Estevan da Guarda has que fiquedes nuu “that you may be left naked”, of a man's wealth.[8] The Miragres de Santiago speak of clothing os que erã nuus “those who were naked” and of a espada nua, an unsheathed sword.[8]

Semantic evolution

Beside “naked”, the medieval language already used the word of an unsheathed sword.[8] Bluteau's dictionary records meio nu “half-naked” and the use of nu for a person in rags.[9] Folqman has espada nua.[10] Later senses extend it to things without covering, leaves or ornament (pés nus, árvores nuas, paredes nuas), to plain unadorned speech and to the undisguised truth, as in a verdade nua e crua.[2][11]

As a noun nu means nakedness and, in the visual arts, a figure of the naked body (nu artístico).[2][12]
