Hyphens and Dashes: Understanding the Differences and Usage

Hyphens (-) and dashes (– or —) are often confused, but they have different functions and usages in writing. Here are the main differences between hyphens and dashes:

Hyphens (-):

1. Hyphens are shorter in length compared to dashes.
2. They are used to join words together or separate syllables at the end of a line.
3. Hyphens are used to form compound words or connect prefixes and suffixes to words.
4. Examples: well-known, high-quality, pre-approval, non-profit.

Dashes (– or —):

1. There are two types of dashes: en dash (–) and em dash (—).
2. Dashes are longer in length and are used to indicate a break or interruption in a sentence.
3. They can be used to set off additional information, emphasize a point, or create a dramatic effect.
4. Dashes are not used to join words or connect prefixes and suffixes.
5. Examples: She opened the door—and gasped. I saw him—the one I mentioned earlier—standing by the window.

The en dash (–) is typically used to show a range or connection between two items, such as dates, times, or numbers:

• The event is scheduled for June 1–5.
• The score was 20–10 in favor of the home team.
• The meeting will take place from 9:00 a.m.–12:00 p.m.

The em dash (—) is used to indicate a more significant break or interruption in a sentence and can replace commas, parentheses, or colons:

• My sister—her name is Lisa—is an excellent pianist.
• I bought all the ingredients—milk, eggs, flour, and sugar—for the recipe.
• The car screeched to a halt—the driver narrowly avoiding the pedestrian.
