How do you pronounce....

[Omnipotent]

Temple of Uglypeople

Temple of Oog ah lee pee

[McGoonagle]

Dynamis:

Just spoke with student of ancient Greek.

The "y" is pronounced like the "o" in "Do." It's same in German (although Y is rare, e.g. Psychrembel.)

Emphasis (complicated rules in ancient Greek) comes in the second syllable in this case. So it's:

Do-NAM-is

[hypnotizd]

And I'll probably still call it Die - na - miss forever. =)
