Re: Question about "do"

>What exactly is the word "do"?
It's an emphatic modifier ("I do clean my room!") in statements.
Presumably, people began using it with questions so much that it is also
an interrogative marker. [/unbased linguistic assumption] Of course, you
don't need more than one interrogative marker per question, so the
question words like "what" and "how" obviate all others.

It's all foma, lies.
