Tantalus

Greek Tantalos, ancient mythical king of Phrygia, a name of uncertain origin, perhaps literally "the Bearer" or "the Sufferer," by dissimilation from *tal-talos, a reduplication of PIE root *tele- "to bear, carry, support" (see extol), in reference to his long endurance, but Watkins finds this "unlikely" and Beekes writes that "An IE interpretation is most improbable." Compare tantalize.
