Parentheses: The way to Use ( ) Accurately
People ask me all the time (and by all the time, I mean never), “Liz, what is your favorite grammatical/punctuational structure?” It’s hard to narrow it down to just one (although you’re probably already aware of my love for the Oxford comma), but if I happened to be in a life-or-death of language situation, it would probably be parentheses, or to be more specific, the parenthetical statement.
I bet you already figured that out.
What Are Parenthetical Statements?
Parenthetical statements give additional information or explanation. They are like softer em dashes.
An em dash indicates an abrupt change in thought or action, while a parenthetical statement is a mild digression.
A parenthesis is like a close friend quietly whispering in your ear, but an em dash is more like your high school graduating class arriving drunk on your doorstep and announcing that you are hosting this year’s reunion, and it’s happening right now. Notice the difference:
Angela exhaled quietly (she didn’t want Frank to hear anything) and felt her way along the wall to the door.
Angela exhaled quietly—she didn’t want Frank to hear anything—and felt her way along the wall to the door.
In the second sentence, the fact that Angela doesn’t want Frank to hear anything has the same importance as her movement towards the door. If that’s your goal, then em dashes are what you’re looking for.
If you’re primarily focused on Angela’s progression towards the door, then use parentheses.
You can also use a parenthetical statement to give your reader information without adding emphasis to the aside:
Kevin yawned (he’d only had four hours of sleep) and stretched out on the floor at his sister’s feet.
The parentheses allow your audience to continue reading through the paragraph without stopping and acknowledging that, oh, Kevin’s lack of sleep is something that I need to pay attention to. Instead, they know that the action isn’t leaving them behind.
The Perils of Punctuating Parentheticals
This is all well and good, but let’s talk about the things that really trip people up: using parentheses and other punctuation. Does the period go inside or outside the parentheses? How about the comma? Let’s clear up this confusion once and for all.
If the part in parentheses is inside a sentence, the punctuation goes outside the parentheses:
Sally felt queasy (maybe eating six cupcakes was a bad idea).
If the part in parentheses is a complete sentence but not within another sentence, the punctuation goes inside the parentheses:
Henry tracked mud across the floor as he came in from the rain. (Sorry, Mom.)
When the part in parentheses is several sentences long, or if it uses special punctuation, like a question mark or exclamation point, the punctuation goes inside the parentheses:
Mark doubted it would rain today (but for the garden’s sake, he hoped it would!).
Emily looked forward to coloring at her grandmother’s house this afternoon (although she didn’t want to use crayons. Did her grandmother have markers? She wasn’t sure).
Note in the second example that there is no period within the parentheses after “She wasn’t sure.” If the final sentence within the parentheses would use a period, there’s no extra punctuation—the period goes outside the parentheses.
Although it’s possible to cram whole paragraphs into parentheses, it’s generally a bad idea. For best effect, use parenthetical statements sparingly, for small asides. Don’t overwhelm your readers with them!
A Note On Parentheses in Academic Writing
We’ve talked mostly about how parentheses show up in every day writing. In formal academic writing, parentheses can be used within the paper to explain or qualify information, but you’re more likely to see them used as reference tools at the end of sentences.
These are called parenthetical citations, and they have their own specific guidelines that you will want to look up in the style guide assigned.
For example, the MLA style guide (used mostly for the humanities) uses parenthetical citations, AKA in-text citations, and a works cited page to tell readers where source information came from. At the end of a sentence with source information, writers will use the author’s last name and the page number inside parentheses to indicate which source from the works cited was used.
Go Use Parentheticals (You Can Do It!)
Do you feel prepared to use parenthetical statements? (It’s okay if you don’t; it just takes practice.) Try using them in your writing, and keep an eye out for the ways other writers have used them.
Who knows? Maybe you’ll find you love them as much as I do (and that’s a lot of love!).
Are parentheticals important in your writing? Let us know in the comments.
Write for fifteen minutes on the following prompt. Use parenthetical statements to enhance your story, and be careful to punctuate them correctly. For extra practice, change your parenthetical statements into em dash asides when you’re done, and take note of how the tone of the story changes.
