Definition of En Dash and Em Dash
The en dash (–) and the em dash (—) are both horizontal lines used to indicate pauses or breaks in thought. However, they differ in length, usage, and meaning. The en dash is slightly longer than a hyphen and is typically used to represent ranges, while the em dash is longer and is often employed to create emphasis or set off information.
What is an En Dash?
The en dash is approximately the width of the letter "N" and is used to indicate a range of values or a connection between two related items. Common uses include:
- Indicating a range of numbers (e.g., 10–20)
- Connecting related terms (e.g., the London–Paris flight)
What is an Em Dash?
The em dash is about the width of the letter "M" and is often used to create a strong break in a sentence. It can replace commas, parentheses, or colons for emphasis. Common uses include:
- Setting off additional information (e.g., She was late—again—to the meeting)
- Indicating an abrupt change in thought (e.g., I was thinking—no, I was dreaming)
Uses of En Dash
Understanding the specific uses of the en dash can help you employ it effectively in your writing. Here are some key applications:
1. Indicating Ranges
En dashes are commonly used to indicate a range of numbers, dates, or time. For example:
- Pages 10–15
- June 1–June 30
- 2010–2020
2. Connecting Related Terms
En dashes can also connect two related items or concepts, emphasizing their relationship. For instance:
- The New York–London flight
- The North–South divide
Uses of Em Dash
Em dashes add emphasis and clarity to your writing. Here are some of the primary uses:
1. Creating Emphasis
Em dashes can be used to emphasize a point or highlight important information. For example:
- She had one goal—success.
- The answer was simple—just ask.
2. Setting Off Additional Information
Em dashes can also set off clauses or phrases that add extra information, making the sentence clearer. For example:
- My brother—the one who lives in New York—just got married.
- The results of the experiment—though inconclusive—were still interesting.
Key Differences Between En Dash and Em Dash
While the en dash and em dash may appear similar, they serve different functions in writing. Here are the key differences:
- Length: The en dash is shorter than the em dash.
- Use: The en dash indicates ranges and connections, while the em dash creates breaks and emphasizes information.
- Appearance: The en dash is often used with no spaces on either side, while the em dash can be used with or without spaces, depending on style preferences.
Examples of En Dash and Em Dash in Sentences
To further illustrate the differences, here are some examples of both en dash and em dash in sentences:
