Can you clear my misconception regarding the following situation?

Question

If anybody asks the question "Who wrote (_)?" where (_) represents the name of a book which already exists and has written content, is the name of that book contained in the question enough to imply a meaning that something is written and not the words "Who wrote" contained in the question?

Answer 1

You would still need a subject (in this case, "who") and a verb (in this case, "wrote") for the question to be complete in English. The book title is the subject of the sentence, but even if you are familiar with the book that was mentioned, it is the verb "wrote" that indicates the speaker is talking about a book or other piece of writing, not the name of the book.

If the speaker asked, "Who wrote 'The Deglenhaine'?", you would still be able to tell that 'The Deglenhaine' is the title of a piece of writing such as a book or a poem, even if you had never heard of that specific piece of writing before.

I hope that helps!
