Prepositions

Q. My question regards the use of “as per.” Example: “As per your request, I enclose a check.” This use has always sounded redundant to me, and pretentious. Isn’t it more correct to say, “As you requested” or “Per your request”?

A. I feel the way you do about “as per,” and conservative dictionaries don’t include it, but Webster’s 11th Collegiate sanctions its use in such constructions without reservation.
