What is a Hyphen?
A hyphen is a short horizontal line (-) used to join words or parts of words together. It is different from a dash, which is longer. Hyphens help clarify meaning and avoid confusion in written English.
When Should You Use a Hyphen?
1. Compound Words
Compound words are formed by joining two or more words together. Sometimes, these words are written with hyphens, sometimes as one word, and sometimes as separate words. Here are the common cases for hyphenated compounds:
- Compound adjectives before a noun: Use a hyphen when two or more words work together as an adjective before a noun.
Example: She is a well-known author.
(But: The author is well known.) - Compound nouns: Some nouns are hyphenated, especially if omitting the hyphen would cause confusion.
Example: My mother-in-law is visiting.
2. Numbers and Fractions
- Numbers from 21 to 99: Use a hyphen in written numbers between twenty-one and ninety-nine.
Example: She is twenty-five years old. - Fractions used as adjectives: Use a hyphen when a fraction is used as an adjective.
Example: Add two-thirds of a cup of sugar.
(But: I ate two thirds of the cake.)
3. Prefixes and Suffixes
Sometimes, you need a hyphen between a prefix (like re-, ex-, or self-) and the base word, especially if:
- The prefix ends and the word begins with the same vowel.
Example: re-enter - The word could be confusing or awkward without a hyphen.
Example: re-sign (to sign again) vs. resign (to quit) - For certain prefixes like self- or ex-.
Example: self-esteem, ex-boyfriend
Common Mistakes with Hyphens
- Overusing hyphens: Not all compound words need a hyphen. For example, “online” is not hyphenated.
- Missing hyphens in compound adjectives: “A high quality product” should be “a high-quality product” when used before a noun.
- Confusing hyphens with dashes: Hyphens (-) are shorter than en dashes (–) or em dashes (—), which serve different purposes.
Tips for Mastering Hyphens in English
- Check a dictionary: When in doubt, look up the word. Many dictionaries indicate whether a word should be hyphenated.
- Practice reading and writing: Notice how hyphens are used in articles, books, or on language learning platforms like Talkpal.
- Remember the position: Compound adjectives are usually hyphenated before a noun, but not after.
