I've just begun using this site and ELU. As far as ELU is concerned, I think I know that at least some prescribed conventions aren't going to be the most favored answers. As in this case. So far, so good.
But is ELL at all different from ELU in this respect? If an ELL questioner asks about "the rule," or what is "correct," or why s/he has been corrected by a teacher for ending a sentence with a preposition, does one answer as she would on ELU? Is the answer different depending on which formulation of the question is used? Or does one acknowledge the "rule" but suggest it's not quite so firm? Or something else?
(Both prescriptive and descriptive answers to this question would be appreciated.)
