Please help our Lands of Intrigue campaign! Is Tethyr a) TETH-ur, b) TETH-UR, or c) Teth-EER? Is Amn 1) AH-men or 2) AH-mm? Would the adjective be “Amnian” or “Amnish”? Thank you! Pronunciations vary across the Realms, so there's no “wrong” answer, but Tethyr is usually “TETH-ear” and Amn is “AWW-mm” (and "Amnian" for fashions, clothes, habits, speech…but "Amnan" for crops/herbs/timber/items). NEVER "Amnish" (too close to real-world Amish).

A pleasure! BTW, If you say "Tethyrian" to denote an item, fashion, or ware (and Tethyr produces fine cloaks and lots of crops, not to mention wines enjoyed up and down the Sword Coast), the emphasis shifts; it's "Teth-EER-ee-an."
