Can someone tell me the proper pronunciation of Mjollnir?

Myol-neer or myol-nair. I couldn't find any resources on it but I am very certain.

Yep, that's about right. Though with my thick New York accent it comes out more like: "Myoll-naar". Whichever way you pronounce it, I'm sure that Thor will understand what you mean.

He'd kick your ass if he didn't like the pronunciation of the word.

Thanks for the help. I was mispronouncing it.
