Et tu, Brute
Et tu, Brute expresses hurt or surprise when someone trusted turns against you, often with a playful touch today; it appears in Shakespeare’s Julius Caesar when Caesar sees Brutus among his attackers.
Where it comes from
Caesar recognises Brutus
The phrase appears in Shakespeare’s play as Caesar recognises a trusted friend among the men killing him. The betrayal makes the attack personal as well as political.
In Julius Caesar, the conspirators surround Caesar and stab him. When Brutus joins the attack, Caesar addresses him before falling.
In Julius Caesar by William Shakespeare
A betrayal, serious or playful
Today the phrase points to unexpected disloyalty, especially from a friend. It can also turn a small disagreement into a joke by treating it like a great betrayal.
In King Lear, Gloucester trusts Edmund with news of his plans to help Lear. Edmund passes that information to Cornwall, turning his father’s trust against him: the kind of betrayal the phrase recalls.

How to use Et tu, Brute
- Use it when an ally unexpectedly turns against you.
- Keep the tone light for a small disappointment.
- Choose plainer words if the literary reference might confuse.
What does Et tu, Brute mean in English?
The Latin asks whether Brutus, too, has turned against Caesar. In everyday use, it expresses disbelief that a trusted person has joined the other side. The name Brute is the Latin form used when addressing Brutus directly.
Did the real Julius Caesar say it?
There is no reliable evidence that Caesar spoke these exact words. The familiar phrase appears in Shakespeare’s Julius Caesar, but ancient accounts differ about Caesar’s final moments. It is safer to treat it as a dramatic moment than as a recorded historical statement.
