TED-ED: Mysteries of vernacular: Jade - Jessica Oreck and Rachael Teel

Jade, a green stone, was historically believed to have medicinal properties, especially for kidney disorders. In the 16th century, the Spanish brought jade to Europe, where it became popular as both a cure and an ornament. The French renamed it jade, a term still used today. In the 19th century, it was discovered that jade referred to two minerals: jadeite and nephrite. Additionally, jade has an English homonym, historically referring to a disreputable woman or a broken-down horse, unrelated to the gemstone.
