When Can a Sentence End with a Preposition?

Here’s an example of a sentence that can end with a preposition: What did you step on? A key point is that the sentence doesn’t work if you leave off the preposition. You can’t say, “What did you step?” You need to say, “What did you step on?

English has a type of verb called a phrasal verb. These are verbs made up of multiple words, and one is always a preposition. “Cheer up,” “run over,” “log on,” and “leave off” are all examples of phrasal verbs, and often sentences that use phrasal verbs end with a preposition:

  • I wish he would cheer up.
  • You should leave it off.

Those are perfectly acceptable sentences.
