the alloy that's mostly copper but lies on your tongue, tasting like silver coins.
means A silvery alloy of copper and nickel, prized for its corrosion resistance and used in coins, marine hardware, and the white metal of much pocket change.
from A straightforward compound: "cupro-" from Latin "cuprum," copper — itself from "aes Cyprium," the "metal of Cyprus," the island the Romans mined heavily for it — joined to "nickel," a word with a grumpier story. German miners blamed troublesome ore on "Kupfernickel," roughly "copper-devil" (Nickel being a mischievous goblin, related to Old Nick), because it looked like copper ore but yielded none. So the name marries the metal of Cyprus to a German imp.
