The characters in Mistborn all have very French names. My girlfriend insists Vin's name is pronounced almost "Veh", as it would be in France, and I'm almost convinced. How do you pronounce it?
The Central Dominance is intentionally French sounding. I say Vin's name like an American would, but everyone in world would say it with a French accent. Same goes for Kelsier, (which they would say Kel-syay.) Again, I say it as an American would, but then I'm not from the Central Dominance.
One further question on pronunciation- Sazed. Is it sayzd, sayzed, or sah-zahd? I always pictured the Terris people as somewhat Arabic so Sah-zahd came more naturally to me, but I'm curious as to what the intended pronunciation is.
I say Sayzed, as does Kelsier. The Terris a is not as harsh as that, but it's not quite a soft "a" either.
