Here's a breakdown of the pronunciation:
* D: Pronounced like the "d" in "dog"
* z: Pronounced like the "z" in "zoo"
* ia: Pronounced like the "ya" in "yacht"
* dek: Pronounced like the "deck" in "deck of cards"
So, the complete pronunciation is "Djah-dek."
Important Note: "DziaDiza" is not a valid Polish word. It seems like a misspelling of "Dziadek".
