What Is an Em Dash?
An em dash (—) creates emphasis, a dramatic pause, or a sudden interruption in thought. It’s not just for stylistic reasons—em dashes can add clarity and impact to your writing.
You might encounter single-em dashes, pairs of em dashes, or even two-em and three-em dashes in specialized contexts. Here are some examples of em dashes in action:
Single em dash:
The concert was unforgettable—loud, energetic, and absolutely thrilling.Pairs of em dashes:
After months of preparation—countless rehearsals and sleepless nights—the show was ready.Em dashes for sudden breaks:
He was about to lock the safe when—CRASH!—a tree fell through the roof. Two-em dash to censor, redact, or indicate missing letters or words:
The document was dated 17—, leaving the exact year a mystery. Three-em dash used in bibliographies to indicate repeated author names:
Rowling, J.K. Harry Potter and the Philosopher's Stone. London: Bloomsbury, 1997. ———. Harry Potter and the Chamber of Secrets. London: Bloomsbury, 1998. —— —.When to Use an Em Dash?
Em dashes are incredibly flexible, but knowing when to use them can make your writing more effective. Let’s explore some everyday situations where em dashes shine.
Set off Appositives
For added emphasis, you can use em dashes to set off appositives—words or phrases that rename a nearby noun. Unlike commas, em dashes draw more attention to the appositive.
Tip: Use a pair of em dashes when the appositive is in the middle of a sentence. Place your sentence outside the dashes if it ends with an exclamation point or question mark.
Here are two examples:
- My best friend—a brilliant writer—just published her first novel.
- The CEO—known for his haphazard methods—surprised everyone with his latest
- decision.
Interruptions or Commentary
Em dashes can replace parentheses to insert interruptions or commentary into a sentence. This technique adds more emphasis than parentheses would.
Examples include:
- She was about to leave—or so she thought—when her doorbell rang.
- The project—despite numerous setbacks—was finished right on time.
Introduce Additional Information
Use an em dash instead of a colon to introduce additional information, especially when creating suspense or emphasizing a point.
Examples:
- After months of speculation, the winner was announced—Jane Smith from Boston.
- He had only one thing on his mind—revenge.
Connect Two Independent Clauses
Em dashes can replace semicolons to connect two independent clauses, particularly when you want to emphasize the connection or create a dramatic effect.
Here are two examples:
- He couldn’t believe his luck—he had finally won the lottery.
- It began to thunderstorm—we had no choice but to stay indoors.

How to Use Em Dashes?
When it comes to using em dashes, the question of spacing often arises. The use of spaces around em dashes largely depends on the style guide you’re following. For instance, the AP Style Guide recommends using spaces before and after em dashes, while the Chicago Manual of Style suggests no spaces.
To create an em dash on a computer, you have several options:
- On Windows: Hold Alt and type 0151 on the numeric keypad, or use the shortcut Ctrl + Alt + minus (on the numeric keypad).
- On Mac: Use the shortcut Option + Shift + hyphen.
- On most word processors: Type two hyphens in a row, and they’ll automatically convert to an em dash.
What Is an En Dash?
An en dash is another punctuation mark. It is shorter than an em dash but is longer than a hyphen. Its primary purpose is to show relationships between words or numbers, mainly ranges. En dashes draw attention to connections, making them invaluable for expressing intervals or contrasts.
Here are a few examples of an en dash in a sentence:
- The store is open 9:00 AM – 6:00 PM daily.
- Please read chapters 3–7 for tomorrow’s class.
- The London–Paris train departs every hour.
- Her career spanned 1995–2020.
- The score was 24–21 in favor of the home team.
When to Use an En Dash?
While en dashes might seem similar to hyphens or em dashes at first glance, they shine in particular situations where you must emphasize relationships between words or numbers. These unassuming marks express ranges, connections, and contrasts visually, clearly, and concisely.
Range of Numbers, Dates, and Time
Use en dashes to represent ranges in numbers, dates, or time. This creates a clear visual connection between the start and endpoints. En dashes in these contexts are read as “to” or “through.”
Here are two examples of how to use an en dash to indicate numerical ranges:
- The conference runs June 15–18, 2023.
- Children aged 5–12 are welcome to join the workshop.
Scores and Directions
En dashes are perfect for showing scores in sports or games and indicating directions or routes.
Examples include:
- The final score was Yankees 6 – Red Sox 4.
- Take the New York – San Francisco flight for your connection.
Add Clarity to Complex Compound Adjectives
Use en dashes to join compound adjectives where at least one part of the compound comprises two or more words or a hyphenated word.
Check out these examples:
- The award-winning New York–based chef opened a new restaurant.
- We studied post–World War II literature in class.
How to Use En Dashes?
In British English, using en dashes with spaces on either side is common instead of em dashes for parenthetical thoughts. For example: “The concert – which was sold out – was a huge success.” However, when using en dashes for ranges, no spaces are needed.
What Is the Difference Between Em Dash and En Dash?
When comparing the em dash vs en dash, you’ll notice that the em dash is wider than the en dash – and yes, there’s a clue in their names! “Em” is wider than “N,” just as the em dash is wider than the en dash in appearance. This visual difference reflects their distinct roles in punctuation.
In the em dash vs en dash debate, it’s important to understand their unique purposes: em dashes are used for emphasis, interruptions, or abrupt changes in thought, while en dashes primarily show ranges or relationships between words or numbers.
Tip: The en dash is your go-to punctuation mark, whether you’re indicating periods, numerical ranges, or complex relationships between words.
How About Hyphens?
Hyphens, en dashes, and em dashes each serve distinct purposes. Hyphens are the shortest of the three and are used to:
- Join compound words (e.g., “well-known”)
- Connect prefixes and suffixes (e.g., “pre-existing”)
- Spell out numbers (e.g., “twenty-one”)
- Separate syllables when breaking words at line ends
- Unlike em dashes, hyphens don’t indicate pauses. They’re purely for connecting related words or parts of words.
Final Thoughts
Mastering the em dash vs en dash usage allows you to add clarity, style, and precision to your work. Remember, em dashes add emphasis and indicate interruptions, while en dashes excel at showing ranges and relationships.
