In case Roman Polanski's version of Shakespeare's tragedy Macbeth and my running commentary aren't enough to help you understand the plot, take a moment to watch this.

That versus Which

Which vs. That

Q: I’ve been writing for a long time and always assumed which and that were interchangeable, but I’ve recently been told that isn’t the case. How do I make sure I’m using the right word? —Anonymous

The battle over whether to use which or that is one many people struggle to get right. It’s a popular grammar question and most folks want a quick rule of thumb so they can get it right.

Here it is:

If the sentence doesn’t need the clause that the word in question is connecting, use which. If it does, use that. (Pretty easy to remember, isn’t it?) Let me explain with a couple of examples.

Our office, which has two lunchrooms, is located in Cincinnati.
Our office that has two lunchrooms is located in Cincinnati.

These sentences are not the same. The first sentence tells us that you have just one office, and it’s located in Cincinnati. The clause which has two lunchrooms gives us additional information, but it doesn’t change the meaning of the sentence. Remove the clause and the location of our one office would still be clear: Our office is located in Cincinnati.

The second sentence suggests that we have multiple offices, but the office with two lunchrooms is located in Cincinnati. The phrase that has two lunchrooms is known as a restrictive clause because another part of the sentence (our office) depends on it. You can’t remove that clause without changing the meaning of the sentence.

You decide... Is he committing a crime, or is the real crime the misplaced apostrophe?
