Word of the Day ~ Fool's Gold

Fool's gold ~ foolz gold

MEANING:

noun: Something that appears valuable but is worthless.

ETYMOLOGY:

Shakespeare wrote in The Merchant of Venice, "All that glitters is not gold." Fool's gold is another name for pyrite, also known as iron pyrite or iron sulfide. Its shiny yellow luster has many fooled into believing they have struck gold while holding a mineral of little value.

The name pyrite is from Greek pyrites (of fire), from pyr (fire) because it produces sparks when struck against a hard surface. Some related words are fire, pyre, pyrosis (heartburn), pyromania (an irresistible impulse to set things on fire), and empyreal (relating to the sky or heaven, believed to contain pure light or fire.).
