  • cobalt \KOH-bawlt\
  • DEFINITION  noun
1: a tough lustrous silver-white magnetic metallic element that is related to and occurs with iron and nickel and is used especially in alloys
2: a strong greenish blue : cobalt blue
  • DID YOU KNOW?

The metallic element "cobalt" ultimately draws its name from folklore. In Middle High German, "kobolt" denoted a usually helpful household elf that engaged in nasty pranks only when it was offended. Later, early Modern German "Kobold" came to refer to a variety of less helpful goblins inhabiting fields and mountains. The variant "Kobolt" in the 16th century was applied by German miners to ores containing the metal cobalt, which they considered to be worthless; they believed that mountain goblins had spoiled adjacent silver ores, or had stolen the silver within the ore. The metal itself in relatively pure form was not produced and described until the 17th century, when "cobalt," with its first letter influenced by New Latin "cobaltum," became part of the international language of science.
