tantalize
Tantalize (verb) means to tease someone by showing them something they want, without letting them have it.
Etymology
From Tantalus (Ancient Greek Τάνταλος (Tántalos)) in Greek mythology, who was condemned to Tartarus in the underworld. There, he had to stand for eternity in water that receded from him when he stooped to drink, beneath fruit trees whose branches were always out of reach. Derived as Tantalus + -ize.
