Adding a wh-word at the end of a statement to make a question
Spoken English:
In speaking, we can sometimes turn wh-questions into statement questions:
What’s today’s date? or Today’s date is what?
1- Declarative
We do this especially when we are checking information that we have already been given or when we want to quickly check a particular detail. These are less formal than full wh-questions:
You have a dog - You have a what?
Your dog is in the yard - Your dog is where?
2- Surprise.
"Hi mom. I thought I'd give you a call to tell you I love you."
"Oh that's so sweet darling!"
"And to let you know I cut off all my hair."
"You did WHAT!?"
3- To clarify meaning
Wife: "Darling, where did you put the mrphmnm?"
Husband: "Where did I put the what?"
"I took your mrphmm."
"You took my what?"
