Is it good grammar to end a request for something with the term, "as far as conveniently possible."
I heard that today and felt it was the most cumbersome phrase I'd ever heard. But is it grammatically correct?
Obiter has said exactly what I meant. The writer is not just expecting assistance, he's acting on the expectation by offering thanks before it's actually been given. The normal thing is to say thanks afterwards.
As in your link: "it conveys the meaning of acting in expectation of an event."
I do dislike TIA - what happens if nobody helps? I'd far rather say "I look forward to your response" then thank them when they've actually done something helpful.
One of the downsides of the abolition of grammar schools is the demise of the teaching of Latin. Even a small competence in that would remove the necessity for such queries.
