What a coincidence meeting you here!
Today, I came across this expression for the first time. I have three questions of this sentence.
- Is "meeting you here" the appositive of "a coincidence"?
- If 1 is correct, must a comma be there between coincidence and meeting as in "What a coincidence, meeting you here!"?
- I think "meeting you here" must be connected to the coincidence by the preposition, of, if we want to get rid of the comma, as in "What a coincidence of meeting you here!".
Please check whether my thinking is correct.
