Etymology: The word "volcanisms" is simply the plural of "volcanism," which names volcanic activity, and it is one of those terms that arrived in English by way of French. Its ancestry runs back to Vulcan, the Roman god of fire and forge-work, whose name in Latin was "Vulcanus." Italian developed "vulcano" from that name for the fiery mountains of the Mediterranean, and French and Spanish followed with their own versions, "volcan" in both. English borrowed "volcan" in its French form, and the word then took on the suffix "-ism," a Greek-derived ending that turns a noun into the name of a process, condition or doctrine. "Volcanism" thus means, literally, the state or activity of volcanoes. The suffix itself came into Latin and then French with the same sense, so the whole word is a layered mix of Roman mythology, Italian place-naming and Greek word-building.
