nah-DEZH-dah
Here's a breakdown:
* nah: The "a" sound is like the "a" in "father"
* DEZH: The "zh" sound is like the "s" in "vision" or the "j" in "genre".
* dah: The "a" sound is like the "a" in "father" again.
It's important to emphasize the "zh" sound, as it is a key element in the name's pronunciation.
