Hyphen
A hyphen is used when two words are joined together to function as an adjective (or compound modifier) before a noun.
(Some stylebooks [e.g., AP Style] retain hyphens after a noun, especially when connected with a to be verb.)
A hyphen is used when two words are joined together to function as an adjective (or compound modifier) before a noun.
Before a noun, hyphenate:
This is a load-bearing wall.
After a noun, no hyphen:
This wall is load bearing.
This wall is load-bearing.
Hyphens are often used with prefixes—letters or words added to the front of an existing word to create a new meaning.
self-service ex-girlfriend all-inclusive cross-country
Hyphens are often used with suffixes—letters or words attached to the end of an existing word to create a new meaning.
