Compound Adjectives

A compound adjective is an adjective that comprises more than one word. Usually, hyphens are used to link the words together to show that it is one adjective.

Examples:

 Please request a four-foot table.
('Four-foot' is an adjective describing the table. A hyphen is used to link 'four'
and 'foot' to show that it is one adjective.)

 It is a 6-page document.

 Claire worked as a part-time keeper at the safari park.

 That is an all-too-common mistake.
