The Rule for Prepositions Is That You Should Not Position A Preposition at the End of A Sentence, Phrase, or Clause.
Like Most Rules, However, There Are Exceptions to That Rule, but Try to Rearrange Your Sentences So That You Have No Dangling Prepositions. Yet, don’t take this rule too far:
“This is the type of errant pedantry up with which I will not put.”
– Winston Churchill – Former Prime Minister of England
