This 9-letter English word comes from the Greek myth of a king (a son of Zeus) who was condemned to a punishment of perpetual, unfulfilled desire. As a punishment from the gods, he was made to stand in a pool of water with fruit trees above him, but the water receded whenever he tried to drink and the fruit moved out of reach when he tried to eat it. Hence this word came to mean “to tease or torment someone by presenting something desirable that remains just out of reach”. (A hint: The Swedish chemist Anders Ekeberg who discovered a metallic element in 1802 gave it a name that is also inspired by this Greek myth! The new element he had discovered just wouldn’t dissolve even in strong acids however hard he tried!)
“Tantalise” is the English word derived from King Tantalus from Greek mythology. The metallic element, of course, is Tantalum.
