Do Balrogs Have Wings?

[Bêthberry]

Obviously what is needed is a full linguistic compilation of all of Tolkien's uses of the word "fly". We need to see his pattern of collocation, the cognates he uses, his contexts, etc etc.

Though mortal Men have little life beside the span of the Elves, they would rather spend it in battle than fly or submit.

My bolding and, to be pedantically precise, I've picked this up quoted by a review, not from the book.
