A hyphen looks like a short horizontal line or dash (-). It is a common punctuation mark primarily used to connect words or parts of words.
Understanding the Appearance of a Hyphen
The hyphen's appearance is distinct: it is shorter than other similar punctuation marks like the en dash (–) or em dash (—). Visually, it is a single, concise horizontal stroke that serves various grammatical and typographical purposes. Hyphens are sometimes simply referred to as "dashes."
Key Functions of a Hyphen
Hyphens play a crucial role in enhancing clarity and readability in writing. Their primary functions include:
- Linking Words: One of the most common uses of a hyphen is to join two or more words, forming a single compound word or a compound modifier. This helps clarify that the words work together as a single concept.
- Indicating a Pause: In some contexts, a hyphen can be used to indicate a slight pause, similar to how a dash might be used, though this is less common than its other joining functions.
- Spelling Out Fractions and Numbers: Hyphens are used when writing out compound numbers (like twenty-one) or fractions (like one-third).
- Dividing Long Words: When a word needs to be broken at the end of a line of text due to space constraints, a hyphen is used to indicate where the word continues on the next line (e.g., com-puter).
Examples of Hyphen Usage
To better understand how hyphens are used, consider these practical examples:
- Compound Modifiers:
- a well-known artist (describes the artist)
- a state-of-the-art facility (describes the facility)
- a long-term plan (describes the plan)
- Numbers and Fractions:
- twenty-five students
- ninety-nine problems
- two-thirds majority
- one-half portion
- Word Division (Hyphenation):
- If a word like "dictionary" needs to be broken at the end of a line, it might appear as:
- dic-tionary
- diction-ary
- If a word like "dictionary" needs to be broken at the end of a line, it might appear as:
- Prefixes: Hyphens are often used to connect prefixes to base words, especially when the prefix ends with the same letter the base word begins with, or to prevent misreading:
- re-elect
- anti-inflammatory
- ex-girlfriend
