Latin plumbum

Pronunciation

  • IPA (Classical): [ˈpɫʊm.bũː][1]
  • IPA (Ecclesiastical): [ˈplum.bum][1]

Forms

plumbum n (genitive plumbī); second declension[1]

Etymology

The origin is uncertain, and it is probably a loanword.[2][3] It was long compared with Ancient Greek μόλυβδος (mólubdos, “lead”), but Beekes argued, and de Vaan accepts, that it is unlikely to be related to the Greek word and is closer to Celtic Proto-Celtic *ɸloudom (“lead”), seen in Old Irish lúaide (“lead”).[2][1] The Celtic word has been explained from Proto-Indo-European *plew- (“to flow”), as “the flowing metal”, but this cannot give Latin plumbum, so the Latin word too is probably borrowed from another language.[2][1] De Vaan mentions a Berber word for lead, itself a loan, as possibly the same wanderword,[2] and Köbler places its source in the Iberian Mediterranean.[4]

Earliest recorded meaning

De Vaan and Köbler date it from Pacuvius, in the 2nd century BC.[2][4] In Pacuvius it means lead used as a missile: “it hails with lead and stones”.[5]

Semantic evolution

The main sense was the metal lead, also called plumbum nigrum, while plumbum album or candidum was tin.[5][6] By metonymy it named things made of lead: a sling bullet, a water pipe, a lead ruler for drawing lines, and in Prudentius a scourge weighted with lead.[5][6] Pliny the Elder also uses it for a livid disease of the eye.[5][6]

In medieval texts it meant a leaden vessel[7] and a seal of lead.[4]

Timeline

  • 220–130 BC – Pacuvius uses it of lead shot.[5][4]
  • c. 50 BC – Caesar reports that plumbum album (tin) is found in Britain.[5][4]
  • 81/79–52/50 BC – Catullus writes of parchment ruled with lead.[5][4]
  • 23/24–79 AD – Pliny the Elder distinguishes black and white lead and names an eye disease plumbum.[5][4]
  • early 14th century – English borrows the word through Old French as English plumb, a lead weight on a line.[8]
