Et tu, Brute? (pronounced (ɛt ˈtuː ˈbruːtɛ)) is a Latin phrase meaning "even you, Brutus? '' It is notable for its occurrence in William Shakespeare 's play Julius Caesar, where it is spoken by the Roman dictator Julius Caesar to his friend Marcus Junius Brutus at the moment of Caesar 's assassination. The first known occurrences of the phrase are said to be in two earlier Elizabethan plays; Henry VI, Part 3 by Shakespeare, and an even earlier play, Caesar Interfectus, by Richard Eedes. The phrase is often used apart from the plays to signify an unexpected betrayal by a friend.
