Grammar Rules: Ending a Sentence with a Preposition
A longstanding grammar myth says we’re not supposed to end a sentence with a preposition. For years, this myth has persisted, tying writers up in knots and making their heads spin around sentences that simply must end with a preposition.
For example: Which store are you going to?
Folks who were taught (and are now attached to the idea) that one should never end a sentence with a preposition will argue that the proper way to write the sentence is as follows: To which store are you going?
But nobody talks that way.
Grammar rules and myths
In the world of writing, grammar myths abound, but where do they come from? I suspect they are born not out of rules but out of rules of thumb. In many cases, it’s not a good idea to end a sentence with a preposition. Allow me to demonstrate:
Where do you work at?
The problem here is not so much that the sentence ends with a preposition. It ends with a completely unnecessary word. Remove that last word and you get a much clearer, more concise, and correct sentence:
Where do you work?
This begs the question: when is it acceptable to end a sentence with a preposition? In fact, what is a preposition?
What is a preposition?
Prepositions are one of the traditional eight parts of speech in the English language. They usually indicate a direction or placement in space (in, on, toward) or perform a similar function in a more abstract and less spatial way (of, for). They tend to indicate a relationship or movement of some kind:
The book is in my hand.
Put the blanket over the bed.
Let’s go to the hall of mirrors.
I have something for you.
The pens are with the paper.
Some of the most common prepositions are: on, in, to, by, for, with, at, of, from, as, under, over, about, above, below, behind, and between. There are plenty more, but you get the idea.
By the way, you can learn a lot more than you ever wanted to know about prepositions on Wikipedia.
When is it okay to end a sentence with a preposition?
If you’ve structured your sentence as concisely as possible, removed any unnecessary words, and the only way to refrain from ending it with a preposition is to make it sound like it arrived in a time machine from the eighteenth century, then you’re probably okay keeping the preposition at the end:
Who are you going with?
What are you waiting for?
We need something to put it in.
As you can see, these are all standard sentences. They adhere to the rules of grammar yet they all end in prepositions. Just try rewriting them without prepositions at the end:
With whom are you going?
For what are you waiting?
We need something in which to put it.
These are all technically correct too, if you don’t mind sounding like you were born three hundred years ago.
Try it for yourself
Take a look at the following sentence:
There’s an idea I never thought of.
There’s nothing technically wrong with the sentence, but we could rewrite it so it doesn’t end with a preposition:
I never thought of that idea.
Which one sounds better to you?
Grammar and common sense
The issue with ending a sentence with a preposition is more a matter of style or rhetoric than grammar. If you want proof, check out this list of references on ending a sentence with a preposition.
So go forth and end sentences with prepositions, but only when it makes sense to do so. Write your sentences to be clear and concise, and you’ll be fine. Keep writing!
