What Is an Infinitive Phrase? (with Examples)
What Is an Infinitive Phrase? (with Examples)An infinitive phrase is the infinitive form of a verb plus any complements and modifiers.
The complement of an infinitive verb will often be its direct object, and the modifier will often be an adverb. For example:
- He likes to knead the dough slowly. (The infinitive verb is to knead. The complement is its direct object (the dough). The modifier is the adverb (slowly). They all make up the infinitive phrase (the shaded text).)

Infinitive Phrases with Bare Infinitives (When Not Preceded by To)Most infinitives are preceded by to, but after certain verbs, the to is dropped. This happens when an infinitive follows can, could, may, might, must, shall, should, will, or would (i.e., a modal verb).
In these examples, the infinitive phrases have a bare infinitive (in bold):
- He should go home immediately.
- They might finish the project by Wednesday.
- Dawn helped her friend bake his mother a cake. (The "special" verb is helped. The direct object is her friend. In the infinitive phrase, the bare infinitive is bake. Its direct object is a cake. This time there is an indirect object (his mother) in the infinitive phrase too.)
- I watched them sweep the road as fast as they could. (The "special" verb is watched. The direct object is them. In the infinitive phrase, the bare infinitive is sweep. Its direct object is the road. The phrase as fast as they could is an adverbial clause.)
