Learn About Em Dashes
While we are learning about the em dash for this lesson, the em dash is part of a family of dashes. Before we learn about the em dash, let’s review the other types of dashes.
Type of dash |
How to type |
Function |
Explanation and Examples |
Hyphen - |
To add a hyphen, use the dash (-) key on your keyboard. |
A hyphen joins words or parts of words |
Always hyphenate the prefix “self.” Example:
Hyphenate a compound modifier when the modifier is located before the word it is modifying. Example: Cindy’s hair is crazy looking when she wakes up. (In this example, the modifier “crazy looking” is after the noun “hair,” so you do not need a hyphen. |
En dash – |
To add an en dash on a Mac, use “option + -”. On a PC, use “Alt + Ctrl + -”. |
An en dash is called by this name because it is roughly the same width as the capital letter N. It represents a range in numbers, dates, or time. |
Generally, you could substitute the word “to” or “through” in place of the en dash. Example: The 2019–2020 season was a wonderful year for Kansas City Chiefs football fans. Kelly walks her dog from 6:00–7:00 every morning. |
The em dash
Now let’s learn about the very versatile (and controversial!) punctuation mark known as the em dash. The em dash got its name because it is roughly the same width as the capital letter M, and the New York Times has called the em dash “the bad boy, or cool girl, of punctuation. A freewheeling scofflaw. A rebel without a clause.” Did you know a punctuation mark could be so scandalous?
Let’s learn about how to use this versatile and controversial punctuation mark so that you, too, can know how to use this “bad boy, or cool girl” in your writing.

Some of my friends—well, most of them, really—don’t understand why I love grammar so much. |
In place of a colon |
My family laughed when I told them what I wanted for my birthday—a new grammar book. |
In place of a semicolon |
Using correct grammar is an important skill to know—it will help readers clearly understand what you want to communicate. |
While em dashes are commonly used in both formal and informal writing, they are often used in poetry, too. A famous poet, Emily Dickinson, is quite famous for her use of em dashes. As you read the following poem, think about how her use of em dashes affects how you read the poem and even its meaning.
“Hope” is the thing with feathers (314)
By Emily Dickinson
“Hope” is the thing with feathers—
That perches in the soul—
And sings the tune without the words—
And never stops—at all—
And sweetest—in the Gale—is heard—
And sore must be the storm—
That could abash the little Bird
That kept so many warm—
I’ve heard it in the chillest land—
And on the strangest Sea—
Yet—never—in Extremity,
It asked a crumb—of me.
