An urn is a large, hollow vase that's usually made of metal or clay. Some urns are used for making coffee or tea, others are made to put someone’s ashes in. Go figure.
Urn is probably from the Latin word urna for "a jar or vessel," but some say it’s from another Latin word urere which means, "to burn.” While some urns are used for making hot drinks, the most common use of an urn is holding the ashes of a dead person. Most urns are decorated. “Ode to a Grecian Urn” by the Romantic poet John Keats (1820), is a poem about the figures on a classical Greek urn.
