In A Crown of Swords, Aviendha has trouble calling Rand, Elayne, Nynaeve, and so on by only their first names. I seem to remember that people from the Age of Legends had three names, Lews Therin Telamon, Elan Morin Tedronai (The Eye of the World, Prologue). What if the Aiel custom of calling people by their whole name is something that came back from the Age of Legends? In The Shadow Rising, we know that Aiel at least date back to the Breaking of the World, when they were entrusted with the ter'angreal, sa'angreal, and angreal of the ancient Aes Sedai. Has this custom been confirmed at all? Or is it a coincidence?
