🎤Pronunciation
🌳Etymology
Origin
This phrase derives from Greek mythology, specifically the legend of Achilles, the greatest warrior of the Trojan War. According to the myth, Achilles' mother Thetis dipped him in the River Styx to make him invulnerable, but his heel—by which she held him—remained untouched by the magical waters, becoming his only mortal weakness. He was eventually killed by an arrow to the heel, and the phrase now metaphorically denotes a seemingly invincible person's single critical vulnerability.
Breakdown
Achilles' (possessive form of the proper name Achilles, the legendary Greek hero) + heel (the rear part of the foot). The phrase combines the hero's name with the anatomical term for the specific vulnerable point that led to his downfall.
