Gold is a relatively soft, shiny precious metal. Many kinds of jewelry, including necklaces, bangles, and wedding rings are traditionally made of gold.
The element itself is called gold, and it's used to make valuable jewels, coins, and as a standard for currency trading. You can also use the word to describe the color, a shiny metallic deep yellow, or to describe things made from the metal: "Check out my new gold earrings!" Gold is an Old English word that shares a Proto-Indo-European root with the word "yellow:" ghel-, which means "yellow or green," and possibly "bright."
