What is the significance of Oedipus's name in Greek mythology?

The significance of Oedipus's name in Greek mythology connects directly to his tragic backstory. The name "Oedipus" translates to "swollen foot," which references the injury he sustained as an infant. According to the myth, after being born to Laius and Jocasta, he was abandoned on Mount Cithaeron with his feet pinned together (swollen) to prevent him from fulfilling the prophecy that he would kill his father and marry his mother. When he was later rescued and raised by another family, he unwittingly fulfilled this prophecy later in life, which adds a layer of irony to his name. This highlights the themes of fate and identity that are central to the narrative of "Oedipus Rex."
