Isn't it a bit curious that many Aes Sedai demand of lesser people that they are called by their name and the "honorific Sedai". After all, many or most Aes Sedai and other educated people should know that "sedai" just means "servant" in the Old Tongue. That basically means an Aes Sedai e.g. wants to be properly adressed by a servant/novice as "Servant Lelaine", "Servant Elaida" or "Servant Cadsuane", for example. On the other hand, it's said that a character like Nynaeve often tries to make a point by never adding the honorific Sedai to the name, though that only means that she doesn't call the Aes Sedai servant.
