Difference Between Hyphen and Dash

Proper punctuation can be the difference between clarity and confusion in writing. Among the various punctuation marks, the hyphen and the dash often create some of the most frequent misunderstandings. But don’t worry. Understanding how to use these two punctuation marks sharpens writing skills and keeps sentences neat and readable.

A hyphen connects two words to create a compound word, while a dash is used to set off parts of a sentence or to create emphasis. Knowing how and when to use each can elevate your writing from mediocre to professional.

What is a Hyphen?

A hyphen (-) is a short line that connects words. It is commonly used to form compound words and to indicate a break in a word’s syllables. Hyphens play a vital role in clarifying meaning and avoiding ambiguity in sentences.

Examples of Hyphen Usage

1. Compound Adjectives: When two or more words form a single adjective before a noun, use a hyphen. For instance, “a well-known author” showcases the adjective “well-known” to describe the author.
2. Word Connections: In compound nouns or modifiers, hyphens link the words for clarity. Take the phrase “sister-in-law.” The hyphen connects “sister” and “in-law” to indicate a relationship.
3. Separating Syllables: Sometimes, hyphens are necessary to break apart syllables in a longer word, especially at the end of a line. “Unbeliev-able” may come in handy when you don’t want to leave a single letter hanging at the end of a line.

In contrast to the dash, the hyphen plays a crucial role in connecting aspects of language, allowing readers to understand the relationships between words without confusion.

What is a Dash?

A dash (—) stretches longer than a hyphen and comes in two distinct types: the en dash (–) and the em dash (—). While both are used to convey additional information or suggest interruptions in thought, they serve different purposes.

Types of Dashes

Two primary types of dashes exist:

1. En Dash (–): This is slightly longer than a hyphen and typically connects ranges or contrasts. For example, you might write “the years 2010–2020” to show a period. It can also appear in a sentence like “the New York–London flight,” indicating a connection between two locations.
2. Em Dash (—): This is the longest dash and serves various purposes. It can replace commas, parentheses, or colons. For example, in the sentence “She was going to—well, she changed her mind,” the em dash provides emphasis and draws attention to the change.

Examples of Dash Usage

1. Creating a Break: An em dash can indicate a sudden break in thought. “I thought I’d win the game—but I lost.” The dash gives the statement a punchier feel and separates the two contrasting ideas.
2. Separating Clauses: Use an em dash to provide additional information or explanations. “My neighbor, an aspiring chef—whose food I often taste—bakes every Sunday.” The dashes around “an aspiring chef” emphasize the extra detail about the neighbor.
3. In place of Parentheses: Instead of using parentheses, an em dash can neatly enclose information. For instance, “The book—originally published in 1995—became a bestseller.” The dashes give the sentence a more fluid look.

When to Use Hyphens vs. Dashes

Knowing when to use a hyphen or dash can help clarify your writing. Here are some key rules:

Hyphen Usage Rules

• Compound Modifiers: Use a hyphen for words that create a single description. “High-quality” products are superior to “high quality” products.
• Number Ranges: When writing number ranges, hyphens are not necessary. Use an en dash. For example, write “ages 5–12,” not “ages 5-12.”
• Prefixes: Some prefixes require hyphens. For instance, “ex-partner” uses a hyphen since “ex” modifies “partner.”

Dash Usage Rules

• Adding Emphasis: An em dash can emphasize a point in the middle of a sentence without needing a full stop. “There’s only one person I trust—my best friend.”
• Contrasts: Use dashes to indicate a contrast in ideas or to introduce an expansion or explanation. For example, “The man loves hiking—despite the blisters.”
• Interruptions: When a thought is suddenly interrupted, an em dash works wonders: “I was going to tell her—but never mind now.”

Examples in Action

Consider a scenario where a writer is crafting a compelling story. They might describe a character using hyphenated terms:

• “The time-traveling historian suddenly found themselves in a decade-long conflict.”

Here, “time-traveling” is a compound adjective that requires a hyphen.

Now, say this writer needed to clarify a plot twist:

• “Just when I thought I understood everything, the twist blew my mind.”

The em dash serves to create a dramatic pause that heightens suspense.

Common Misuses to Avoid

Sure, punctuating correctly can be tricky, and mistakes can happen. Here are some common pitfalls.

Mistaking a Hyphen for a Dash

One common error is using a hyphen where a dash is appropriate. Consider the sentences:

• Incorrect: “I love reading fiction—especially fantasy.”
• Correct: “I love reading fiction—especially fantasy.”

The incorrect version uses a hyphen instead of an em dash, which creates a less emphatic pause.

Overusing Hyphens

Another frequent mistake is over-hyphenating. For instance, “a well-known, talented author” needs only one hyphen to connect “well-known.” Keep it simple to maintain clarity in your writing.

Confusing En Dash and Hyphen

Writers sometimes confuse en dashes and hyphens. When indicating ranges, such as time or scores, use an en dash. “The meeting is from 3–5 P.M.” is the correct format, contrasting “The meeting is from 3-5 P.M.,” which is wrong.

Hyphens and Dashes in Different Styles

Different writing styles, whether it’s APA, MLA, or Chicago, have specific rules regarding hyphens and dashes.

APA Style

In APA style, hyphens are used for compound adjectives before nouns. Dashes should be em dashes without spaces on either side. You might write “The 2010–2020 report” in APA format.

MLA Style

MLA allows hyphens in the same scenarios you’d expect. With dashes, it also advocates for em dashes that correctly emphasize or provide interruptions, like “He thought he could win—until the last lap.”

Chicago Manual of Style

Chicago’s approach is similar but includes some additional notes about how hyphenation can affect word breaks at the end of lines, advising writers to check for readability and appearance.

Practical Applications in Writing

Understanding the correct usage of hyphens and dashes can enhance clarity in different writing scenarios, be it fiction, nonfiction, or even content writing.

Fiction

For fiction writers, punctuation can tightly weave the narrative. Using em dashes can create breakpoints that mirror characters’ thought processes or infuse excitement into dialogue.

Example: “I can’t believe—wait, did you hear that?” Here, the broken thought mimics the character’s surprise.

Nonfiction and Technical Writing

In technical or informative writing, clarity is key, making the correct use of hyphens and dashes paramount. Proper compound modifiers can specify information clearly and make for smoother reading.

Example: In an article about a multi-national corporation, a sentence like “The multi-national firm achieved unprecedented growth” correctly includes a hyphen to clarify the compound adjective.

Blogging and Online Content

Bloggers benefit from employing dashes to lead readers through lists and explanations, keeping them engaged. The em dash can be a valuable tool to summarize or re-emphasize points effectively.

Example: “Traveling is an adventure—discovering the unknown, meeting new people, experiencing different cultures.” This usage draws readers into a shared experience.

Best Practices for Using Hyphens and Dashes

To ensure your writing remains clear and professional, consider adopting these best practices:

1. Know Your Audience: Tailor your usage based on whether you are writing for a formal publication or a casual blog. Hyphens and dashes may require greater scrutiny in academic writing.
2. Read Aloud: Hearing how the sentence flows can help determine whether a dash or hyphen is appropriate.
3. Consistent Formatting: Stick to style guide recommendations throughout your writing for formatting hyphens and dashes. Consistency contributes to professional writing.

Tools to Help with Punctuation

If you’re unsure about punctuation, various tools available can assist you:

• Grammar Checkers: Tools such as Grammarly or the Hemingway App can point out hyphens and dashes misusage.
• Writing Apps: Specialized writing software often helps identify when and where punctuation should be applied.
• Style Guides: Keeping significant style guides on hand, both online and in print, can serve as quick references to clarify punctuation rules.

Quick Reference Guide

Hyphen (-):

• Connects words or syllables.
• Use for compound words (e.g., well-known, twenty-five).

En Dash (–):

• Indicates a range or connection.
• Use for numbers or related items (e.g., January–March).

Em Dash (—):

• Creates emphasis or an interruption.
• Use for dramatic pauses or added insights (e.g., “It was the best day ever—until it rained”).

Additional Information

Understanding the subtle differences between a hyphen and a dash can elevate your writing.

• Hyphen (-): This is primarily used to connect words and separate syllables. For instance, in “well-being” or “mother-in-law,” the hyphen links each component into a single concept.
• En Dash (–): Slightly longer than a hyphen, this punctuation mark is used to indicate a range, such as in “pages 10–20,” or to show a connection between two related items, like “the New York–London flight.”
• Em Dash (—): Even longer, the em dash serves as a versatile punctuation mark. It can replace parentheses or colons to emphasize a break in thought, as in “I was happy—all things considered. It wasn’t easy.”
• No Spaces: Hyphens and dashes are unique in that they do not have spaces on either side. In contrast, an em dash often can stand alone with spaces, depending on style preferences.
• Typographical Variations: On a computer, hyphens are easily accessed through the keyboard, while en and em dashes often require special commands or shortcuts, making them less frequent in casual writing.
• Consistency Matters: The misuse of these marks can disrupt clarity. A well-placed en dash can connect related ideas. Meanwhile, a hyphen can create confusion when applied incorrectly, such as in “small-business owner” versus “small business owner.”
• Editorial Style Guides: Different style guides have specific rules for hyphens and dashes. For example, the Chicago Manual of Style has distinct guidelines for when to use an en dash versus an em dash, which can vary from the AP Stylebook’s recommendations.
• The Mysterious Space: An em dash can be used with or without spaces around it, while an en dash typically does not have spaces, depending on the style guide followed.
• Historical Roots: The distinct origins of these punctuation marks trace back to typesetting traditions, where their physical lengths helped differentiate their purposes.
• Keyboard Shortcuts: On most keyboards, you can create a hyphen by simply pressing the hyphen key. For an em dash, you might need to use a keyboard shortcut—for example, pressing “Alt + 0151” on a numeric keypad for Windows. En dashes can be made by using “Alt + 0150.”
