Origins
From New Latin molybdaena (“any of various substances resembling lead, including lead and molybdenum, their sulphides, and graphite”), from Ancient Greek μολύβδαινα (molúbdaina, “a plummet”), from μόλυβδος (mólubdos, “lead; graphite”), from an Anatolian word cognate with Lydian 𐤪𐤠𐤭𐤦𐤥𐤣𐤠 (mariwda, “dark”), from Proto-Indo-European *morkʷ-iyo-, from a root *morkʷ- (“dark”). Attested since the last quarter of 18th century.
