Vesuvium

Part of speech: noun

Definitions

1. A stratovolcano located on the Gulf of Naples in Italy, known for its catastrophic eruption in AD 79 that buried the cities of Pompeii and Herculaneum; also referring to geological features and volcanic activity associated with this mountain
2. An Italian volcano famous for explosive eruptions that have caused significant historical damage; it also denotes the volcanic structures and phenomena linked to this prominent mountain near Naples
3. A volcano in southern Italy renowned for its deadly eruption in the 1st century causing widespread destruction; the term also encompasses the geological formations and eruptions originating from this volcanic peak

Etymology: The mountain that buried Pompeii and Herculaneum in 79 AD is called Vesuvius in English, and "vesuvium" is a Latinized variant of that name, not the usual English form. Its ancient origin is unclear. Scholars have not settled on a meaning or a language for the name, so any etymology given with confidence would be guesswork. The Latin-style ending is what gives the form its interest. Mineralogists later drew on the mountain's name for a mineral found in its lava, which was called "vesuvian" and eventually "vesuvianite." That mineral name is the more durable legacy of the mountain's name in English, and it shows how a place name can outlast the volcano's fame to label rock.

Synonyms: Mount Vesuvius, volcano, stratovolcano
