Oedipus complex
Freud's parental-desire hypothesis
Today this word meansFreud's hypothesis that a child feels attachment to the opposite-sex parent and rivalry toward the same-sex parent.
Freud borrowed the name from Oedipus, who unknowingly killed his father and married his mother.
In the myth, what matters is that Oedipus did it all without knowing — it was never what he wanted.
Worth noting
Outside psychoanalysis, it is not widely supported as a theory today. A concept's fame and its scientific standing are different things.
