We say 'Please tell me what is the matter'. But can we say 'Please tell me what the matter is' without changing the meaning?
I thought of this when I read in a grammar book written by a Chinese professor of English: Tell me who he is. And also: Tell me who is he.
Thank you very much.
We "shouldn't" say anything in language, Joham, save for what we need to express our meaning and feelings/emotions.
The non-question form is the normal neutral, the other is more emphatic.
Girl A: Did you see the new boy in school. What a dreamboat!
Girl B, C and D: Tell us, who is he?!!
======================
A: I'm having a problem.
B: [exasperated with A who always complains to B] Tell me - what IS the problem?!!
