Wait, so you guys pronounce it In-chor-oy, with "ch" as in change? I always said Inkoroi (in most cases I assume "ch" is "k", like Achamian, though are some exceptions, like Chigra).
I've also always pronounced Cishaurim with a soft C. Never even thought about the snake aspect. But yeah, someone on Westeros (I believe Trisky) pointed out that their tribes is the Indara-Kish, or something along those lines. K's and C's are weird.
Like Cujara'Cinmoi. I always say Kujara'Sinmoi, but I feel that's not correct. I also say Sillvendi, though that's just a habit.
