A tighter novel helps keeps readers engaged in the story.

When I first started writing, my novels were long. Like, seriously long. This isn’t unusual for a new writer, and like countless ones before me, I set out to learn how to trim some of those excess words from my manuscript.

One of the things I discovered was the, “words you don’t always need” advice. On that list was “cut prepositions.”

I’d learned enough about writing at that point to know you shouldn’t heed advice without understanding the reasoning behind it, so I sat down and studied why prepositions and prepositional phrases were so awful.

What I found was—they aren’t.

They’re a lot like adverbs. They can muck up your writing when used poorly, but very effective when used well. It’s also a lot easier to say “don’t use them” than it is to explain why they can be a problem.
