Alea iacta est

Alea iacta est

Meaning: "The die has been cast."
It means a decision has been made and there’s no going back. You’ve committed, and now you have to deal with the consequences.

Pronounced: AH-lay-ah YAK-tah est
Said by Julius Caesar in 49 BC when he crossed the Rubicon River with his army — starting a civil war.

Sentence:

Quick way to remember:
Alea iacta est = Point of no return. Like throwing dice — once they leave your hand, you can’t change the roll.
