I know I posted two duplicate questions, but I entered the wrong title for the first question. So I think I had to post another one. Thank you.
Hi, Could you please tell me what is the difference between who she is and who is she?
Thank you very much.
Hello. "Who is she?" is a question and a complete sentence.
"Who she is" is not a complete sentence. It needs a subject and verb to complete it. For instance, you might write, "I do not know who she is." Or you might make a question of it by writing, "Can you tell me who she is?"
Notice that when you use it in this way you change the word order.
