Phrasal Verbs

Unit 10
Phrasal Verbs Used as Nouns
Many two-word phrasal verbs can be used as nouns. All the phrasal verbs in this unit have a
noun form. Notice that the two-word noun is sometimes written with a hyphen:
verb: go ahead noun: go-ahead
and sometimes as one word:
verb: lay off noun: layoff
Unfortunately, there is no rule that will help you to always know which form to use. Also,
because not everyone agrees on which nouns should be hyphenated and which should be
written as one word, you will sometimes see a noun written both ways. If you are not sure,
check your dictionary or do an Internet search to see which way is more common.
