When Do You Use Parentheses In An Essay

Tips for using brackets (parentheses) effectively

Writers, have you ever found yourselves with a great deal of important information that you want to include in a sentence but had difficulty finding a spot for all of it? Fitting everything into a sentence can be tricky, but this is where brackets are useful. Brackets (parentheses) are punctuation marks used within a sentence to include information that is not essential to the main point. Information within parentheses is usually supplementary; were it removed, the meaning of the sentence would remain unchanged. Intrigued? Keep reading!

Help! There are so many kinds of brackets!

There are four main types of parentheses that can be used in writing. However, not all of them are acceptable for use within all fields of writing. The four main types of brackets are:

  1. Curved Brackets or Parentheses (…) are the most commonly used and are the focus of this article.
  2. Square Brackets […] are most often used to include additional information from an outside source (someone other than the original author).
  3. Curly Brackets {…} are often used in prose to designate a list of equal choices.
  4. Angle Brackets <…> are typically used to enclose and illustrate highlighted information.

This article focuses on the use of curved parentheses (as they are the most common type in everyday writing). Curved brackets serve different purposes depending on the style of writing they are used in, e.g., they can be used in formal documents and in informal documents for two completely different purposes.

Formal writing

In formal writing, parentheses are often used to provide supplementary information within a sentence. This information is not essential to the sentence, but the reader will benefit from knowing it.  For example, when referring to a member of a company in a formal document, it is not uncommon to see "Mr. Adam McCabe (CEO, LulzTV.com) expressed profound sadness upon hearing of the bard’s death." Here, had the bracketed information been left out, the meaning of the sentence would not have changed, but the reader benefits from knowing the additional information about Mr. McCabe.

Informal writing

If you've read Virginia Woolf's novel Mrs. Dalloway, then you already know about the use of parentheses to represent a character's innermost thoughts. These thoughts are expressed within brackets and are not spoken aloud for other characters to hear. Brackets are used heavily within stream-of-consciousness writing as a way for the author to show the reader what a character is thinking without having to create dialogue. Be careful though, because the overuse of parentheses can lead to a cluttered and confusing text.

Citations

If you have ever written an academic paper, then you have undoubtedly used curved brackets for your in-text citations. These citations usually occur at the end of a sentence and provide the reader with the source of the information that the author used in the sentence. You will often see these in academic journals, for example: "It has been said that the origin of the spoon dates back to the Middle Paleolithic, when man began using the hollowed out shells of small turtles to sip water (Ferreira, 1986)." The information in the parentheses is essential, not to the meaning of the sentence, but to avoid plagiarism.

Punctuation

Our editors often come across common errors involving brackets and punctuation.

Here is an example of punctuating parentheses:

Incorrect: I went to the mall yesterday. (even though I had no money)

Correct: I went to the mall yesterday (even though I had no money).

Since the information in the parentheses is part of the sentence, it must be placed inside the period.

Using brackets—whether in a business plan or a short story—can be an effective way to include extra information in a sentence. Although they can be useful, try not to use brackets excessively or the clarity of your writing will suffer. If you're struggling with the use of brackets, then send your document to our academic editors.

There is no hard-set rule for using parentheses to set off items in a series. That's good news for you because that means you have quite a few options from which to choose. Get creative and choose one of the following options that best represents your style. Notice I said ONE of the following. Consistency is best in that it makes your writing cohesive and doesn't confuse your readers.

Use Parentheses to Enclose Supplemental Information

This "supplemental information" includes asides, tangents, and afterthoughts. In general, anything that can be removed from the sentence without altering its meaning can be enclosed in parentheses. Take a look at the following examples to get a better idea of what counts as extraneous material.

Sometimes you may not know whether or not you are dealing with a noun that is singular or plural. At other times, you may actually try to hide from your audience how many (if any) of the nouns are present. If the idea of not knowing in advance how many of a thing you are writing about (or intentionally trying to hide that number) confuses you, just look at the following examples.

Use Parentheses to Indicate an Acronym

When writing, it is often much easier to substitute an abbreviation for an unwieldy word (or set of words).

In MLA style, it's actually required to do so.

Whew! For such unobtrusive marks of punctuation, you can sure get quite a bit of use out of parentheses. One last word of warning: as with all things in life, use parentheses only in moderation. Even the most tolerant of readers can become irritated by a set of parentheses every other word.
