noun
(Greek myth) Greek hero, the son of Peleus and the sea goddess Thetis: in the Iliad the foremost of the Greek warriors at the siege of Troy. While he was a baby his mother plunged him into the river Styx making his body invulnerable except for the heel by which she held him. After slaying Hector, he was killed by Paris who wounded him in the heel

Greek hero of the Trojan War stories, son of Thetis and Peleus, his name is perhaps a compound of akhos “pain, grief” (see awe) + laos “the people, a people” (see lay (adj.)); or else it is from a pre-Greek language.
Achilles [(uh-kil-eez)]

In classical mythology, the greatest warrior on the Greek side in the Trojan War. When he was an infant, his mother tried to make him immortal by bathing him in a magical river, but the heel by which she held him remained vulnerable. During the Trojan War, he quarreled with the commander, Agamemnon, and in anger sulked in his tent. Eventually Achilles emerged to fight and killed the Trojan hero Hector, but he was wounded in the heel by an arrow and died shortly thereafter.

Note: People speak of an “Achilles’ heel” as the one weak or sore point in a person’s character.

Note: The Achilles tendon runs from the heel to the calf.

Note: Achilles is the hero of Homer’s Iliad.

Note: The phrase “wrath of Achilles” refers to the hero’s anger, which caused so much destruction that Homer refers to it as his main theme in the first line of the Iliad.
