Forms

neto m (plural netos, feminine neta, feminine plural netas, diminutive netinho)[1] Houaiss records netos and neytos in the 13th century and nepto in the 14th.[2]

Etymology

The word for the grandson is a masculine made on the feminine, from Portuguese neta (“granddaughter”), written Old Galician-Portuguese neto in the oldest texts.[2][3][1][4] The feminine continues Late Latin nepta, a form of neptis (“granddaughter; niece”), which Du Cange finds often in 8th-century capitularies.[2][3][5] Houaiss explains that the Latin masculine nepōs (“grandson, nephew”) did not live on in Spanish and Portuguese, so a new masculine was made from the feminine.[2] The DLP and Estraviz derive the word instead from Vulgar Latin *neptus, a remodelling of the Latin masculine, and Nascentes cites Adolfo Coelho and Nunes for that form, with a plural meaning “grandsons” in a Latin charter of 867–912.[6][7][8]

The same pair is Galician neto and Galician neta, Spanish nieto and Spanish nieta, and Catalan net and Catalan neta.[9][7] Corominas calls the Spanish masculine, recorded in 1062, a form proper to the Hispanic languages, drawn from the feminine.[10]

The Latin noun goes back to *neptis, from Proto-Indo-European *néptih₂ (“grandchild, sister's son”).[1]

Earliest recorded meaning

Latin charters already write neptos for grandsons in 867–912, and Houaiss's first date, 995, is the Latin nepta that Machado found.[11][8][2] In Galician-Portuguese the word is recorded from the 13th century: the Cantigas de Santa Maria speak of a man who took great pleasure in his children and his grandsons (dos seus fillos e dos netos mui gran prazer recebia), and the Cancioneiro da Ajuda has it as the masculine of neta.[11][3]

Semantic evolution

The Crónica Troiana calls Pyrrhus the neto of Peleus, and the Crónica Geral uses the word throughout.[11] Bluteau (1712) gives terceiro neto, the son of a great-grandson.[12] In the plural netos also means descendants, posterity.[2][13]

In the old Portuguese bullfight the neto was the horseman who carried the president's orders.[2][6] Portuguese slang uses the word for a glass holding five decilitres, and in the Minho it is a shoot of cabbage.[2][6][13]

Pronunciation

  • Brazil: /ˈnɛ.tu/[1]
  • Portugal: /ˈnɛ.tu/[1]

Forms

neto (feminine neta)[19]

Etymology

The word for “clean, pure” is borrowed from French net (“clean, clear”).[2][3][20][21] Houaiss dates the French word to 1120 and traces it to nitidus (“polished, shining; clean”), of which Portuguese nítido is the learned form.[2] The French word is from a contracted Vulgar Latin *nittus.[1] The Latin adjective is formed from niteō (“to shine”), and its sense “pure, clean”, first found around 400 AD, lives on in the Gallo- and Italo-Romance languages.[1]

Nascentes (1955) instead took the Portuguese adjective straight from the Latin word, through a contracted form, citing Adolfo Coelho and Cortesão, and compared nédio “sleek”.[8] Spanish neto is likewise a borrowing from the Catalan or French word or from Italian netto.[22][9]

Earliest recorded meaning

Houaiss's first record is from 1443, in the sense “very clear, translucent, limpid”;[2][3] Cunha dates the word to the 16th century.[2][3] Morais quotes Camões's pérolas netas “flawless pearls”.[23][13]

Semantic evolution

Morais (1813) defines the adjective as “clean, without defect”.[23] The sense “clear, bright” is now obsolete: Aurélio quotes it from the poet Alberto de Oliveira.[19][2] Wikcionário records a commercial sense, of a quantity counted without its packaging.[24]

Timeline

  • 1443 – Houaiss's first record.[2]
  • 16th century – Cunha's date for the adjective.[3]
  • 1813 – Morais records neto “clean, flawless”, with Camões's pérolas netas.[23]

Meanings

Adjective

  1. (obsolete) Very clear, limpid, bright; nítido.[2][19][25]
  2. clean, spotless, without defect.[21][13]
  3. smooth.[25][24]
  4. net: of a product or weight counted without its packaging.[24]

Usage notes

Neto is also a Portuguese surname: Bluteau notes a Pero Neto who signed a Lorvão document dated in the era 1206, that is AD 1168.[12] Nascentes explains it as a cognomen given to someone who bears the same name as his grandfather.[26]
