Generally, hyphenate two or more words when they come before a noun they modify and act as a single idea. This is called a compound adjective.

an off-campus apartment
state-of-the-art design

When a compound adjective follows a noun, a hyphen is usually not necessary.

Example: The apartment is off campus.

However, some established compound adjectives are always hyphenated. Double-check with a dictionary or online.

Example: The design is state-of-the-art.

Hyphens with High or Low
When using high or low as part of a compound adjective, use a hyphen when the compound comes before the noun it’s modifying. Some examples of compound adjectives using high and low include high-level/low-level and high-impact/low-impact
