Parentheses are used to deemphasize and separate nonessential information from the rest of the sentence—you know, things the writer didn't have to say, but wanted to.


These are called asides. (And yes, Shmoop loves 'em.)

The aside doesn't directly belong; it clarifies something, directs the reader, or speaks to the writer's frame of mind. You could separate asides out with commas or dashes, but the more random they are, the more you should consider using the warm, grammatical embrace of parentheses.

Punctuating Parentheses

Now that you're on board with parentheses, let's talk about punctuation. If the aside is a complete statement, the terminal, or end, punctuation goes inside the parenthesis, like this:

I have many symptoms. (I'm coughing, sneezing, and itching.)

If the aside isn't a complete sentence, but comes at the end of the sentence, the terminal punctuation goes outside the parenthesis, like this:

I have many symptoms (coughing, sneezing, itching).

What about if the aside is a complete sentence within a sentence? No sweat! Don't capitalize it, and only include terminal punctuation if it needs a question mark or exclamation point. Here's one more example to please the parenthetical gods:

Craig loves (we mean he truly adores) fish.

The aside we mean he truly adores is a complete sentence. Notice that it's not capitalized and, since it doesn't need a question mark or exclamation point, there's no terminal punctuation nestled inside the parenthesis either.



"Righteous Kill may be a terrible film, but it's one of only two films (along with Heat) where Robert DeNiro and Al Pacino share the same scenes."

In this cinematic sentence, along with Heat belongs in parentheses because it's additional information that, while interesting, isn't essential to the main idea of the sentence.

"Five Guys (over 1,000 locations nationwide) has built a cult-like following for their mouthwatering burgers and fries."

We firmly believe that barbecue sauce is essential to a Five Guys bacon burger. In this particular example, the number of locations Five Guys has is not essential to the main point of the sentence. Therefore, it belongs in parentheses.

"Charlotte would never make it past the first round of auditions on American Idol. (But don't tell her that.)"

Dashing poor, tone-deaf Charlotte's dreams of pop superstardom isn't integral to the main idea here. Since it's an aside, it belongs in parentheses.
