Is it really correct to say such a thing as, “We are waiting on your mother,” when referring to the anticipation of the arrival of someone’s mother? It would seem to me that it would be more appropriate, if not more comfortable (at least for the lady), to “wait for your mother.”
One can wait on the corner, and one can wait on a table (if that is his profession), but does one really want to wait on his dinner?
It seems to me that the preposition “from” has been replaced by “on” when used in conjunction with the word “wait.”
It makes me cringe! Lately, I’ve heard it so often, I must look like a victim of St. Vitus Dance!
