I've always wondered what is the accepted pronounciation of some of the words in the 40k universe, il note here how I pronounce them, but I am willing (and happy to be corrected)
Slaanesh - Slarn-esh
Tzeentch - Zeent-ch
C'Tan - K-Tan (or is it like Sir-Tan)
I also thought it would be nice for there to be a collected 'database' on the pronounciation of some of the more complex words
Cheers
