Over time, "aes Cyprium" was shortened to "cuprum" in Latin, ultimately giving rise to the modern English term "copper".
2. "Vitriol" - The term "vitriol" comes from the Latin phrase "vitriolum" or "vitriolus". It was used to refer to a specific chemical compound, namely "green vitriol" or "ferrous sulfate", which contains iron.
