Infinitive Phrases

Infinitive Phrases Definition and Structure

Infinitive phrases can have various structures, depending on the context and complexity of the sentence. Here are some common components you may find in an infinitive phrase:

• Infinitive verb: The base of the phrase, which includes "to" followed by the base form of the verb (e.g., to learn, to eat, to play).
• Direct object: A noun or pronoun that receives the action of the verb (e.g., to eat cake, to play football).
• Adjectives or adverbs: These words modify the verb or the direct object, providing additional information about the action (e.g., to eat chocolate cake, to play footballwell).
• Prepositional phrases: These phrases provide context or further detail about the action (e.g., to learn about history, to go to London).

It is essential to distinguish between the basic infinitive verb and the entire infinitive phrase because the latter can perform different functions within a sentence.

Infinitive Phrases Examples

Now that you have learned about the definition and structure of infinitive phrases let's look at some examples to help you get a better understanding of their usage in sentences.

As you practice identifying and incorporating these phrases, you will become more comfortable with their usage and structures, leading to enhanced language skills.

Infinitive Phrases in Different Functions

Infinitive phrases, as previously mentioned, can serve various functions within a sentence. They can act as adjectives, subjects, or adverbs, providing essential information and clarifying the purpose of other words in the sentence. In this section, you will explore these three functions in more detail, including examples to better understand their usage and application

Infinitive Phrases As Adjectives

When an infinitive phrase functions as an adjective, it modifies a noun or pronoun by providing more information about it. This function helps create a clearer and more accurate description of the noun or pronoun. Characteristics of infinitive phrases as adjectives include:

• They are placed directly after the noun or pronoun they modify
• They often involve a relationship between two entities; the noun they modify and the action expressed by the verb

To recognise when an infinitive phrase is functioning as an adjective, ask yourself whether the phrase is providing more information about a specific noun or pronoun in the sentence. If so, then it is acting as an adjective.

Examples of Infinitive Phrases As Adjectives

Here are several examples illustrating the use of infinitive phrases as adjectives in sentences. Note how each phrase provides additional information about the nouns or pronouns they modify.

    She bought a book to improve her vocabulary.
    (The infinitive phrase "to improve her vocabulary" modifies the noun "book.")
    

    He needs a partner to practice dancing.
    (The infinitive phrase "to practice dancing" modifies the noun "partner.")
    

    They found a place to relax after work.
    (The infinitive phrase "to relax after work" modifies the noun "place.")
    

Infinitive Phrases As Subjects

Infinitive phrases can also function as subjects in a sentence. When used in this way, they describe the action or state that the sentence focuses on or discusses. They often appear at the beginning of the sentence and are followed by a verb. Some characteristics of infinitive phrases as subjects include:

• They usually appear before the verb in the sentence
• They can often be replaced by gerund phrases, which also function as subjects

To identify infinitive phrases as subjects, ask yourself whether the phrase is describing the primary action or state being discussed in the sentence. If so, then it is functioning as a subject.

Examples of Infinitive Phrases As Subjects

Here are some examples demonstrating the usage of infinitive phrases as subjects in sentences. Observe how each phrase serves as the primary focus of the sentence, describing the action or state being discussed.

    To see the northern lights is fascinating.
    (The infinitive phrase "to see the northern lights" is the subject of the sentence, describing the fascinating experience.)
    

    To travel around the world is a lifetime goal for many people.

    To understand advanced mathematics requires persistence and patience.
    (The infinitive phrase "to understand advanced mathematics" is the subject of the sentence, describing a challenging process.)
    

Infinitive Phrases As Adverbs

Lastly, infinitive phrases can function as adverbs. When used in this manner, they modify verbs, adjectives, or entire clauses by providing more information about the action or state being described. Common characteristics of infinitive phrases as adverbs include:

• They usually provide a reason or purpose for the action expressed by the verb
• They are often introduced by words like "to", "in order to", or "so as to"

To detect whether an infinitive phrase is functioning as an adverb, consider if it provides more information about the verb, adjective, or clause it modifies. If so, then it is acting as an adverb.
