Writers Must Know the Difference Between an Em Dash, an En Dash, & a Hyphen

WARNING! Grammar nerd content ahead. 

 

Today I'm sharing the answer to one of my personal pet peeves—the incorrect use of punctuation. But instead of a rant, I'm going to equip you to do this correctly.

 

I run into this issue with writers all the time—even with experienced writers. So today I’m going to give you the grammar short course and you’ll be an expert on the differences and know the best choice for every writing situation. 

 

You may ask why it matters, but the fact is we want to be accurate when we communicate through the written word. And each of these punctuation marks carries a different meaning. 

 

What’s the Difference?

 

1. A Hyphen (incorrectly referred to as a dash)

 

This is the shortest of the three. A hyphen is used between words or parts of words. This isn’t interchangeable with the other two types of dashes. The following are several times when a hyphen is used, but it’s not an all-inclusive list. 

 

Examples:

Hyphenate compound words: 

• daughter-in-law
• three-year-old
• six-pack

Hyphenate compound modifiers that work together as a single adjective:

• We need a baby-friendly restaurant.

But don’t hyphenate words if the noun comes first:

• Is that restaurant baby friendly?

Hyphenate numbers

Numbers between twenty-one and ninety-nine should hyphenated when they’re spelled out.

• There are twenty-seven teenagers in the youth group.

Hyphenate numbers that are the first part of a compound adjective, whether they a numerals or spelled out:

• My recent social media class was 60-minutes long.
• My son loves thirteenth-century insults.

Don’t hyphenate numbers if the number is the second part of the phrase:

• There isn’t an exit 3 on that highway.

Hyphenate words with the prefixes ALL-, Ex-, Self-

• That is her ex-husband.
• The dog chewing on the bone looked self-satisfied.

2. An En Dash

This is longer in length than a hyphen. It is used to indicate a range of numbers or a span of time. I remember it because it really is a replacement for either the words through or to.

 

Examples:

• The party was from 5:00pm–7:30pm.
• I read pages 25–101 in my English book. 

3. An Em Dash

An em dash is the longest of these three. I remember them by knowing that the letter N is shorter than the letter M.

 

An em dash is used in similar circumstances to a colon, but is less formal and generates stronger emotion. It also can replace a parenthetical phrase.

Examples:

• Awkward: Susan loved three things: fall, coffee, and walking in the rain.
• Better: Susan loved three things—fall, coffee, and walking in the rain.
• Awkward: After waiting several seconds, the speaker continued (choosing to ignore the rude interruption).
• Better: After waiting several seconds, the speaker continued—choosing to ignore the rude interruption.

How do I make them on my keyboard?

En Dash

To insert an EN DASH when typing on a Mac or a PC, type in this order:

• the word
• space 
  
• single hyphen
• space
• the next word
• space 

After the last space, the hyphen will change to an EN DASH. Depending on whether you are following the AP Style guide (leave the spaces in before and after the finished en dash) or the Chicago Manual of Style (take the extra spaces out before and after the finished en dash) you will need to make your finished product CONSISTENT.

 

Em Dash

To insert an Em Dash when typing on a Mac or a PC, type in this order:

• the word 
• NO space 
• two hyphens without any spaces between them
• NO space
• the next word
• space

After the last space, the hyphen will change to an Em Dash.

 

NOTE: When tweeting or texting, all these rules go out the window. Those two forms are very casual ways of communicating and I've given up with being a grammar snob there. 

 

Bottom Line:

This is a crash course in how to correctly use these three punctuation marks. What questions do you have about when to use them or how to create them on your computer? Leave your comments below.
