The word "volcano" itself evolved from the Latin "Vulcanus" through various stages of development:
* Vulcanus (Latin)
* Vulcan (Medieval Latin)
* Volcano (Italian)
The name "Vulcanus" was applied to the volcanic island of Vulcano in the Aeolian Islands, Italy. From there, the term spread to other volcanic formations and eventually became the general term for any mountain that erupts with molten rock, ash, and gases.
