In the first chapter of Le Morte d'Arthur is the sentence, "And so by means King Uther sent for this duke, charging him to bring his wife with him, for she was called a fair lady, and a passing wise, and her name was called Igraine."

What does "and a passing wise" mean?

>her name was called

Whoever translated this sucks at English. I wouldn't be surprised if it was erroneous.
