We had a thread on
Idony a few weeks ago, if you are looking for more answers.
EYE-do-nee. But I know that it is incorrect. Apparently it's id-O-nee or something. Or ID-o-nee. And it was common in the Middle Ages.
I personally only like it as EYE-do-nee. I think you can use any pronunciation you want because it is so uncommon that you cna choose.
