"Achilles' heel" is an idiom that comes from Greek mythology, specifically from the story of Achilles, a legendary Greek hero of the Trojan War. According to the myth, Achilles was invulnerable except for his heel, which his mother, Thetis, had failed to dip in the River Styx when she held him as a baby. As a result, his heel remained his one weak spot. The term "Achilles' heel" refers to a person's vulnerability or weak point, despite overall strength or invincibility. It's often used metaphorically to describe any weakness that could potentially lead to downfall or failure, whether in an individual, a system, or an organization.
