we would be much appreciated, if you ...
Hi!
We have a small linguistic dispute with my friends; perhaps someone could help us to solve it being a native speaker, if he or she would not mind. We have found out that there are more than 3.5 millions exact matches in Google for an English expression "we would be much appreciated, if you"… We suppose that the mining of it is something like “we would be very grateful, if you…” that might be a kind of a polite request, but we believe it to be wrong in grammar. Could any one, please, clarify it for us, is it possible/correct to use this expression?
How do you think what may be a reason for such common incorrect use (I do think it is incorrect)?
