ah-LAY-ah ee-AK-tah est
Here's a breakdown:
* Alea: Pronounced "ah-LAY-ah" with the emphasis on the first syllable.
* iacta: Pronounced "ee-AK-tah" with the emphasis on the second syllable.
* est: Pronounced "est" like the English word "best".
Important Note: While "Alea iacta est" is a Latin phrase, it's often pronounced with a more English-sounding emphasis. You'll hear it pronounced with the emphasis on the first syllable of "iacta" ("ee-AK-tah") more often than with the emphasis on the second syllable. This is because the original Latin pronunciation is difficult for most English speakers.
So, while the technically correct pronunciation is "ah-LAY-ah ee-AK-tah est", you'll also hear "ah-LAY-ah ee-AK-tah est" used quite often.
