If you are in a conversation and you don’t know the answer, where do you go? Have you considered looking up the origin? Find the key term mentioned and look up it’s Etymology. Etymologies are not definitions; they’re explanations of what our words meant and how they sounded 600 or 2,000 years ago. If you want to have a good conversation, start with the etymology.
Here is something I looked up on Etymoline. The word “Volcano” originated in the 1610s, from Italian vulcano “burning mountain,” from Latin Vulcanus “Vulcan,” Roman god of fire, also “fire, flames, volcano” (see Vulcan). The name was first applied to Mt. Etna by the Romans, who believed it was the forge of Vulcan. Earlier form in English was volcan (1570s), from French.
