Achilles was the son of Thetis and Peleus, the bravest hero in the Trojan war, according to Greek mythology.
When Achilles was born, his mother, Thetis, tried to make him immortal by dipping him in the river Styx. As she immersed him, she held him by one heel and forgot to dip him a second time so the heel she held could get wet too. Therefore, the place where she held him remained untouched by the magic water of the Styx and that part stayed mortal or vulnerable.
To this day, any weak point is called an “Achilles’ heel.”
因而成為希臘神話裡特洛伊戰爭中的英雄Achilles唯一的弱點。Source(s): 教授講的+ http://www.wordexplorations.info/Achilles-heel-sto...
