Grammar Explanation: Descriptive PhrasesPages 262-266

Some adjective clauses can be shortened to descriptive phrases.

We can shorten and adjective clause in which the relative pronoun is followed by the verb to be.

Compare:Sentence with an adjective

clause:

• People who are unhappy about the amount of spam they receive should write their lawmakers.

Same sentence with a descriptive phrase:

• People unhappy about the amount of spam they receive should write their lawmakers.

clause:

• Pierre Omidyar, who is the founder of e-Bay, is one of the richest men in the world.

• Pierre Omidyar, the founder of e-Bay, is one of the richest men in the world.

A descriptive phrase can begin with a past participle.

This happens if you drop the relative pronoun and verb “to be” from an adjective clause in the passive voice:

clause:

•One half of all the e-mail that is sent today is spam.

•One half of all the e-mail sent today is spam.

clause:

•There are about 78 million items that are listed on e-Bay.

•There are about 78 million items listed on e-Bay.

clause:

•There are about 78 million items that are listed on e-Bay.

•There are about 78 million items listed on e-Bay.

A descriptive phrase can begin with a present participle (-ing form).

This happens if you drop the relative pronoun and verb “to be” from an adjective clause the present or past continuous tense:

clause:

• A man who is living in Florida retired at the age of 37 after making millions in the spam business.

• A man living in Florida retired at the age of 37 after making millions in the spam business.

clause:

•Shoppers who are using e-Bay can locate a hard-to-find item.

• Shoppers using e-Bay can locate a hard-to-find item.

A descriptive phrase can give a definition or more information about the noun it follows.

This kind of descriptive phrase is called an appositive.

clause:

•Spam, which is unwanted e-mail, is an annoying problem.

• Spam, unwanted e-mail, is an annoying problem.

clause:

•eBay, which is an auction Web site, is very popular.

•eBay, an auction Web site, is very popular.

A descriptive phrase can begin with a preposition:

clause:

•A man who is in Florida retired at the age of 37.

•A man in Florida retired at the age of 37.

clause:

•Pierre, who is from France, created e-Bay.

•Pierre, from France, created e-Bay.

A descriptive phrase can be essential or nonessential:

clause:

• People who are unhappy about the amount of spam they receive should write their lawmakers.

• People unhappy about the amount of spam they receive should write their lawmakers.

clause:

• Pierre Omidyar, who is the founder of e-Bay, is one of the richest men in the world.

• Pierre Omidyar, the founder of e-Bay, is one of the richest men in the world.

However, an appositive is always non-essential:

clause:

•Spam, which is unwanted e-mail, is an annoying problem.

• Spam, unwanted e-mail, is an annoying problem.
