" An evil of the ancient world is seemed, such as I have never seen before" said Aragorn " It was both a shadow and a flame"
He has never SEEN before.It never says he doesn't know what one is, though even if he didn't know what it was he guesses near enough.
Of course, Tolkien makes misatkes, but most often he corrects them.
And, I believe that in the BOOK it is Aragorn, not Legolas who recognises the Crebain.
