Using Hyphens
What is a hyphen?
A hyphen a mark of punctuation used to divide and connect separate elements of individual words. Though it looks quite similar to a dash, the hyphen is used to clarify meaning in particular words rather than in whole sentences.
A HYPHEN IS USED TO COMBINE WORDS
Compound Words
A compound word is created when two words are combined to make a new word with a new meaning. Missing hyphenation can change the meaning of the word(s). Hyphenated compound words are usually used to describe nouns.
Examples
(Without the hyphen) Look! There’s a man eating shark!
(With the hyphen) Look! There’s a man-eating shark!
Fractions

Examples
(Missing the hyphen) We must add two thirds to get the correct answer.
(With the hyphen) We must add two-thirds to get the correct answer.
Numbers
In numbers twenty‐one through ninety‐nine In English, these numbers require hyphens in writing.
Examples

(With the hyphen) I gave the waitress twenty-five dollars and she never gave me change!
To connect prefixes to nouns and adjectives
A prefix is placed at the beginning of a word to modify or change its meaning. Usually, hyphenated prefixes are used to separate two consecutive vowels to avoid confusion.
Examples
(Missing the hyphen) I need to de ice my car.
(With the hyphen) I need to de-ice my car.
To connect a single letter to a word
This usage usually designates an action.
Examples
