Pronunciation

  • UK: /vɒlˈkeɪ.nəʊ/, /vɒlˈkɑː.nəʊ/[1]
  • US: /vɑlˈkeɪ.noʊ/, /vɔlˈkeɪ.noʊ/[1]

Etymology

It is borrowed from Italian vulcano (“burning mountain”) (also volcano),[2][3][4][5] ultimately from Latin Volcānus (also Vulcānus), Vulcan, the Roman god of fire and metalworking,[2][3][5] whose name was also used for fire, flames and a volcano.[2][4] The Romans applied it to Mount Etna, which they believed was Vulcan's forge.[2][4][6] The OED notes that Italian vulcano is first found in 1555 in translations of Spanish accounts of the Americas, and that its use as a common noun followed volcán;[3] the American Heritage Dictionary takes the Italian word from that Spanish one or from volcão.[7] Earlier English forms were vulcane (late 14th century) and volcan (1570s), from volcan and Spanish.[2][4]

Earliest recorded meaning

A mountain or hill with a crater or vent through which lava, rock and gases are or have been thrown out: 1613, in Samuel Purchas's Pilgrimage, spelled vulcano;[3][4][8] Etymonline dates it to the 1610s.[2] The spelling volcano is recorded from 1690.[4]

Semantic evolution

Merriam-Webster's Book of Word Histories notes that the Romans placed Vulcan's forge under Etna, while the Greeks set Hephaistos's on the volcanic island of Lemnos.[9] Johnson (1755) defined the word simply as "a burning mountain".[10] Figurative use for a person or thing liable to burst out violently is recorded from 1690, and for a suppressed violent passion from 1697.[3] The word was also applied to a violent eruption of fire or smoke (1699) and to things that throw out fire like a volcano, such as a cone-shaped firework (1785).[3] The rare verb, to erupt or to utter explosively, dates from 1867.[3]
