Pronunciation

  • /ˈplomo/, [ˈplo.mo][1]

Forms

plomo m (plural plomos)[1] Old Spanish texts have plomo and, more rarely, plonmo and promo.[2]

Etymology

It continues inherited from Latin plumbum (“lead”).[3][4][5][1] The same Latin word is Portuguese chumbo, Galician chumbo, Asturian chombu, Aragonese plomo, Catalan plom, Occitan plom, French plomb, Italian piombo and Romanian plumb.[6][7][3]

The initial ⟨pl⟩ is unexpected: in inherited words Castilian turns it into ⟨ll⟩, as in llano, and García de Diego notes that no Castilian form with ⟨ll⟩ is found, while the Portuguese and Galician forms show the regular development.[7][3][1] Meyer-Lübke took the Spanish word for a loan from Catalan, and Cuervo thought it might come from Aragonese.[6][3] Corominas holds both possible and says more evidence is needed.[3] He thinks a Mozarabic origin unlikely, since Mozarabic would have kept the ⟨mb⟩, although most Spanish lead today comes from Almería; before the reconquest of Almería, he suggests, lead may have come from Aragon or Catalonia, where it is mined.[3] He does not rule out a conservative pronunciation of the upper classes for the name of a metal, but rejects Cuervo's idea that the following /m/ preserved the /p/ by assimilation.[3] Wiktionary adds the possibility that it is a semi-learned word taken early from Latin.[1] Portuguese also has the learned prumo (“plumb line”).[8]

The Latin word was traditionally compared with Ancient Greek μόλυβδος (mólubdos, “lead”), a link that de Vaan, after Beekes, rejects.[9][10][1] De Vaan connects it rather with a Celtic word for lead, Wiktionary's Proto-Celtic *ɸloudom, but since the two cannot be derived from one Indo-European form, both are probably loans from another language.[9][1] Boutkan and Kossmann point to a Berber word for lead.[9][1] The Academy calls the Latin word one of Hispanic origin, and the DHLF a loan from a Mediterranean language, perhaps Iberian, since lead came from Spain.[5][11]

Earliest recorded meaning

The earliest record in a Spanish text kept in its original is a pact of friendship of 1242, which mentions a king's seello de plomo “lead seal”.[12] Corominas's first date is 1243, in a document published by Menéndez Pidal, and he also cites the Libro de Apolonio (c. 1240, in a 14th-century copy), where a character escriuyó en hun plomo con hun grafio d'azero letras “wrote letters on a sheet of lead with a steel stylus”.[3][4][12]

Semantic evolution

In the 13th century the word named the metal, as in Alfonso X's Lapidario (a stone en su peso semeia al plomo “is as heavy as lead”), and also a weight of lead, as in his astronomical works of 1277.[13] Nebrija gave both the metal and the mason's plomo, the plumb line.[3] Covarrubias (1611) explained estar a plomo la pared “the wall stands plumb” by the small lead weight at the end of the mason's cord, and desplomada for a wall out of true.[14]

The Autoridades (1737) added any piece of lead, such as weights or the sinkers of nets, and by metonymy bullets, with a quotation from Calderón.[15] The Academy's 1817 edition recorded the colloquial sense of a tiresome person, said in es un plomo.[16] In the 19th century plomo was also the lead seal put on cloth at factories and customs.[17] Modern Spain uses the plural plomos for the fuses of an electric circuit.[5][18] In much of Latin America plomo is also an adjective, “lead-grey”, and in Mexico it can mean a gunfight.[19][20][21]
