When you join two or more words to form a single modifier preceding a noun, add a temporary hyphen: a two-year-old child. If the same words appear after the noun, a hyphen is usually not necessary: the child was two years old. However, some compound modifiers are permanently hyphenated, such as first-class, well-known, part-time, and old-fashioned. Check a dictionary to be sure.
Hyphen Rules to Remember
- Do hyphenate a compound modifier before a noun. (She ran a home-based business.)
- Do hyphenate permanent compounds before or after a noun (The office was old-fashioned.)
- Do not hyphenate combinations including adverbs that end in ly (Our newly decorated offices look great.)
- Do not add hyphens involving prefixes such as non, pre, over, and super (nonabrasive, nonbearing, preseason, overpaid, and supersmart).
Add or delete hyphens as appropriate in the following sentences. Mark “C” if a sentence is correct.
