barro m (plural barros)[1]

Etymology

Its origin is disputed.[2][3] Houaiss takes it to be inherited from Vulgar Latin *barrum (“clay, mud”), a pre-Roman base, perhaps related to the stems of barranco.[2] Cunha, Machado, the Aurélio and Michaelis also call it pre-Roman, and Machado notes that its Romance relatives are disputed.[4][5][6][7] The DLP thinks it may be a Hispanic Latin word, while Priberam calls its origin controversial and Porto obscure.[8][3][9] Wiktionary takes the base to be Paleo-Hispanic, possibly Celtic, comparing broch (“waste, dregs”) and *barros (“bushy end”), as the DLE does.[1][10]

The same word is Galician barro, Spanish barro and Asturian barru.[1] Corominas dates the Spanish word to 1250–1280 and finds it in Gascon and Languedocian too.[11] The REW also lists it in Occitan, and derives from it Spanish barraca.[12] Older scholars thought of an Arabic word for earth, an idea Engelmann and Gonçalves Viana held and Silva Bastos still offered with a question mark.[13][14]

Earliest recorded meaning

Houaiss and Cunha date the word to the 14th century.[2][4] Machado quotes a list of goods with louça outra de barro que aqui fazem, “other pottery of clay that they make here”, and argues that the word must be older, since its derivatives are recorded much earlier: barrosa in a Latin charter of 968, Barrosum as a surname in 1111 and barreiro in 1128.[5] A Santiago register taxes pedra et barro, “stone and clay”, the mixture of earth and water used in building.[15]

Semantic evolution

The first sense is clay as material for building and for pottery: Cardoso, Barbosa and Pereira render it with Latin argilla and creta, and Bluteau calls it a rich earth for making jugs and crockery.[16][17][18] Bluteau already has the proverbial tirar barro à parede, and Morais in 1789 explains lançar barro à parede as to try whether something can be achieved.[18][19] By metonymy the word names a clay object or figure, and so something of little worth.[2][6] In Brazil it is also an informal word for excrement, and in Portugal for money.[2] In southern Brazil it is the usual word for the mud of wet roads and fields.[20]

  • 1712–1728 – Bluteau records the phrase tirar barro à parede.[18]
  • 1789 – Morais explains lançar barro à parede.[19]

Usage notes

Lançar or atirar barro à parede means to make an attempt and see whether it succeeds.[19][3]

The plural barros “red pimples on a young man's face” is a word of separate origin: the DCECH derives the Spanish and Portuguese word from Latin varus “pimple”.[2][23] An old barro “hamlet, small farm”, recorded by Viterbo in medieval documents, is a form of bairro.[24][25]
