Explore the intricate world of hyphens, en dashes, and em dashes—the unsung heroes of punctuation that can transform your writing. In this article, we’ll delve into the proper usage of these punctuation marks according to AP style, uncovering their ability to add drama and coherence to your sentences. Whether you’re a seasoned writer or a budding wordsmith, understanding the nuances of dash and hyphen usage is essential for crafting captivating and impactful prose.

Key Takeaways:

  • Hyphens, en dashes, and em dashes are essential punctuation marks that can enhance your writing style and create meaningful connections between thoughts.
  • The en dash (–) is slightly longer than a hyphen and is often used in specific style guides for indicating ranges, such as between years.
  • The em dash (—) is longer than the en dash and is beloved by writers for its ability to signify abrupt changes, pauses, and clauses within a sentence.
  • Overusing em dashes can diminish their impact, so it’s important to use them judiciously and reserve them for special occasions.
  • Hyphens (-) are joiners that connect compound words and compound modifiers, but their usage can vary based on individual style preferences.
  • Understanding when to use hyphens and when to omit them is crucial for maintaining clarity and readability in your writing.

The En Dash (–): The Subtle Connector

Let’s begin with the en dash, a punctuation mark that is slightly longer than a hyphen but shorter than an em dash. The en dash, often the width of the letter “N,” has limited usage in AP style, primarily employed for indicating ranges between two values, such as years. In general, most writers need not worry about its usage unless following a style guide that specifically prescribes its use for certain contexts.

The Em Dash (—): A Dramatic Pause

The em dash, longer than both the hyphen and en dash, is a versatile punctuation mark that holds immense power in adding drama and impact to your writing. In AP style, the em dash should be set off with spaces on both sides to ensure clarity.

Widely loved by writers and occasionally despised by editors, the em dash is most commonly used to signify abrupt changes within a sentence or to create a pregnant pause. Its primary purpose is to introduce a quick diversion from the main subject of the sentence and then return to the main thought. However, it’s crucial to exercise caution and avoid overusing em dashes, as their effectiveness can diminish if employed excessively.

Here are a few examples to illustrate the usage of em dashes:

  • I write sins — not tragedies.
  • She sometimes — but not always — remembers the difference between em and en dashes.

Aside from indicating pauses and sudden shifts in thought, em dashes can also be used for setting off a clause within a sentence, creating attribution for a quote, denoting a series within a phrase, or even appearing in datelines.

The Hyphen (-): A Joiner and Clarifier

Among the three punctuation marks, the hyphen is the smallest but undoubtedly one of the most helpful. According to AP style, hyphens are considered “joiners” used to connect compound words together. However, the usage of hyphens is not standardized and often subject to individual style preferences.

When deciding whether to use a hyphen, the primary consideration should be readability. If using a hyphen improves the flow and clarity of a sentence, it is appropriate to include it. Conversely, if a hyphen makes the sentence more challenging to read or understand, it is best to omit it.

Hyphens are commonly used for compound modifiers when two or more connected words precede a noun. For instance, “how-to guide” or “small-business guide.” It’s important to note that this rule only applies when the compound modifier comes before the noun. If it appears after the noun, a hyphen is not necessary.

However, not all compound modifiers require a hyphen. Here are a few instances when a hyphen is not needed:

  • Commonly used terms where the meaning is clear, such as “sixth-grade teacher” or “climate change bill.”
  • If more than three words modify a noun, using hyphens can often obscure rather than clarify the meaning.
  • Adverbs that include “very” or words ending in “ly.”
  • Words describing dual heritage, such as “African American” or “Asian American.”

In addition to compound modifiers, hyphens can also be used for compound nouns that may not be read as one thought, certain prefixes and suffixes, and to avoid confusion between cognates or consecutive vowels.


The nuances of dash and hyphen usage may appear daunting, but they are essential tools in the writer’s arsenal for creating impact and coherence. By mastering the appropriate usage of en dashes, em dashes, and hyphens, you can elevate your writing to new heights, captivating your readers and conveying your ideas with clarity and precision.

Remember, punctuation marks are not merely decorative flourishes; they are powerful instruments that shape the rhythm and meaning of your sentences. Embrace the dash and hyphen, and wield them with purpose to enhance the artistry and effectiveness of your prose.
