An infinitive phrase consists of an
infinitive and any modifiers or complements
the infinitive has. The entire phrase
can be used as a noun,
an adjective, or an adverb.
An infinitive is a verb form
that can be used as a noun,
adjective, or an adverb. Most infinitives
begin with the word to.
Examples of Infinitive Phrases:
As a noun: Jeremy loves to
play fetch with his gray dog.
As an adjective: I need a
book to read at school.
As an adverb: She went to
the supermarket to buy cereal.
Occasionally, the infinitive sign to is
omitted and replaced by words such
as can, would, did, or should.
