[ASoIaF] Can a woman be knighted?

Say Jaime decides to go through the knighting ceremony with Brienne while they're in King's Landing. Any knight can make a knight, and she goes through a vigil at the Great Sept and is annointed with the seven oils and so on (Jamie threatens anyone who objects). Is she now a knight? If not, why not?

This is a question of perception and clout - a bit like asking, "who is the rightful king of Westeros?" It depends a great deal on who you ask, and how much power they have to press their claim.

Certainly Brienne is a knight as far as Jaime is concerned, and he's one of the most powerful men in Westeros. And she's physically imposing enough that a lone commoner would be unlikely to vocally challenge her claim.

She certainly enjoys more knightly privileges than she would if, say, her dad had knighted her, or if she were built like Sansa. And she'd almost certainly be treated more like a knight in Dorne than at the Dreadfort.

This is a huge theme of the books: power resides where men believe it resides.
