I made up the sentence:
I proclaimed myself king.
How to form correct questions?
- Who proclaimed myself king?
- Who did I proclaim myself?
- Who did I proclaim king?
Please, correct my sentences.
- Who proclaimed me king?
"Myself" is used when the subject and the object are both you. Because you are asking "who" here, you don't know who the subject is. Thus, you can't use "myself".
- What did I proclaim myself?
King is a title here, and so it is a "what". For comparison, King James is a "who".
Your third question is fine. You could answer it with your given sentence, or simply "Myself."
