Dryden is also believed to be the first person to posit that English sentences should not end in prepositions because Latin sentences cannot end in prepositions.[22][23] Dryden created the prescription against preposition stranding in 1672 when he objected to Ben Jonson's 1611 phrase the bodies that those souls were frightened from, although he didn't provide an explanation of the rationale that gave rise to his preference.

Try to avoid ending a sentence with a preposition. This is not really a rule, but lots of people think it is. So, to ensure you don't annoy your readers, just avoid the situation. If rewording your sentence makes it sound too contrived, just go for it and end your sentence with a preposition. (Sometimes, the cure is worse than the "problem.")

One of the most frequent questions I’m asked is whether it’s acceptable to end a sentence with a preposition.
I know many of you were taught that you shouldn’t end a sentence with a preposition, but it’s a myth. In fact, I consider it one of the top ten grammar myths because many people believe it’s true, but nearly all grammarians disagree, at least in some cases (1, 2, 3, 4, 5, 6, 7, 8). - See more at: http://www.quickanddirtytips.com/education/grammar/ending-sentence-preposition?page=all#sthash.BLjDqgXf.dpuf
