What is an Infinitive Phrase?
An infinitive phrase consists of an infinitive form of a verb along with any modifiers and complements.
An infinitive verb is the “to” form of a verb. Any verb expressed as “to sing,” “to jump,” etc., is an infinitive verb.
For example, read these phrases –
- To wash bedroom curtains.
- To go on a vacation.
- I asked the students to revise properly.
- I want to go home quickly.
All the above phrases are examples of infinite phrases.
Infinitive phrase components
You already know the rough breakdown of an infinitive phrase. Here are more details about the components –
Infinitive – An infinite or infinite verb is the “to” form of the verb. When used in a sentence, an infinite verb does not give any specific duration.
For example –
- He likes to jog
Here, “to job” is an infinitive. We don’t know if he will ever stop jogging.
Now, read this example –
- He wanted to jog today
Here, “to jog” is not an infintive. We know he wanted to jog on a specific day.
Object – Any noun or pronoun which gets the action of a verb in the sentence is called the object of the sentence.
Here are some examples –
- To play chess
- To watch a match
- To attend class
- To eat fruits and vegetables.
Here is an example of an object used in an infinitive phrase (in italics) –
- She likes to take notes thoroughly.
The complement in this sentence is “notes,” as it is the direct object of the infinitive verb “to knead.”
Modifiers – Words or phrases which add more meaning to a noun or pronoun. Modifiers can act as an adjective or adverbs in a sentence based on their use.
Modifiers make the words more expressive in a sentence.
Here are some examples –
- To walk slowly.
- To laugh heartily.
- To cry softly.
- To wash thoroughly.
- To risk haphazardly.
When used in an infinite phrase (in italics), a modifier will work like this –
- He wanted to drive home slowly.
In this sentence, the modifier is “slowly” as it tells us how the subject (“he”) wanted to drive his vehicle. The infinitive verb in the sentence is “to drive,” and the complement or object is “home.”
