My opinion is probably worthless, but I'll add my 2cents. I have a horrible track record with pronouncing things, so maybe you should look at how I say it and avoid using it.
Sanguinius? San (sort like sand without the d)-gween-ee-us (short u, like up)
Perturabo? PER-tur (like turn without the n)-uh-boh (like bow-ties).
Vulkan? Vul-KUHN. Like the Star Trek ones.
Jaghati? I don't even try. I just look at it and I know what I'm reading. Thankfully I don't bring his name up much in conversations.
P.S. I'm an American from the Pacific Northwest. Your pronunciation of the word examples I gave may differ.
Thanks and no-one's opinions are worthless
I've not actually heard anyone pronounce Perturabo like you so again, all these years thinking it's one way and you've proved it can be pronounced differently.
When I started out in the hobby as a kid it seemed like I got the majority of words wrong
I've forgotten all the others but I'm sure they'll come to me
I pronounce Sanguinius - Sang-gween-ius
Perturabo the first way you suggested
Alpharius the second way you suggested
Ahh now to me Tyranids is Ti (pronounced like tid to rhyme with lid but without the d) - a - nids so thats another one I've got to query with myself now.
Schaeffer for me is shay (to rhyme with gray) - fer
Thanks for your input on the others, I always thought it was San - gwin - ee - us like in the word Sanguine but equally I can see how it's San - gween - ee - us too
Ok, time to mess up some word, I'm from south-east America, please forgive me.
Note: a capitol letter mean I am actually saying the name of that letter.
Sam Hain... sam hAn
Oh man I don't even try with the Tau words
For me Abaddon is A - bad - un but I'm definitely supporting the cuh - tan pronunciation rather than see - tan. I've not heard the jag - hate - ee pronunciation before so that's opened my eyes. The others I pronounce like you even tho I'm from the UK
I couldn't help myself.
Oh man, I'd not even thought of these.
I have no idea how to pronounce skitarii although when I'm reading my mind reads it as skit - are - ee but I realise that's probably wrong.
Cataphracti in my mind is cat - a - fract - eye but again I have no idea if that's right.
