Other forms: parapraxes
When you slip up and say something you didn't mean to say, it may be a parapraxis — a mistake that reveals something hidden in your unconscious mind.
It's more common to call a parapraxis a Freudian slip, a glitch in your memory or a misspoken word that seems to expose an unconscious wish, fear, or conflict. Both the word parapraxis — from the Latin para-, "contrary," and the Greek praxis, "a doing," — and the term Freudian slip arose from the theories of Sigmund Freud, who invented psychoanalysis. Freud himself first called these slips Fehlleistungen, "faulty actions" in German.
