In the books, an interesting revelation about the prophecy comes courtesy of Maester Aemon, the elderly, blind maester of the Night's Watch. Aemon, Sam, and Gilly are on their way to Oldtown, and during a stop in Braavos, Sam hears rumors about Dany's dragons. He tells Aemon about it, who then fills Sam in on the Azor Ahai prophecy. It turns out that, technically, the word "prince" in Old Valyrian — the language in which the prophecy was originally written — is derived from the word "dragon," for which there is no gendered term. This means that even though the prophecy is later translated to "prince," it could just as easily mean "princess."
The Maester then becomes totally convinced that Daenerys is the prophesied leader, saying, "Daenerys is the one, born amidst salt and smoke. The dragons prove it." Aemon's theory is further supported by the woods witch, or the Ghost of High Heart, who once said that the prince that was promised would be born from the bloodline of Prince Aerys and Princess Rhaella Targaryen, who just happen to be Dany's parents.
