What is an Infinitive Phrase?
An infinitive phrase is a grammatical structure that consists of an infinitive verb along with its modifiers and complements. It functions as a noun, adjective, or adverb in a sentence. The main component of an infinitive phrase is the infinitive verb, which is the base form of a verb preceded by the word “to.” For example, “to run,” “to eat,” or “to study” are infinitive verbs.
The structure of an infinitive phrase typically includes additional words that modify or complete the meaning of the infinitive verb. These modifiers and complements can include adverbs, adjectives, nouns, pronouns, prepositional phrases, or even entire clauses. They provide additional information about the action or state expressed by the infinitive verb.
Functions and Uses of Infinitive Phrases
Infinitive phrases can function as nouns, adjectives, or adverbs within a sentence.
When serving as nouns, infinitive phrases often act as the subject, object, or complement in a sentence. For example, “To learn a new language is challenging” (subject), “She wants to visit Paris” (object), or “Her goal is to become a doctor” (complement).
As adjectives, infinitive phrases modify or describe nouns. For instance, “He needs a place to study” (modifying the noun “place”) or “The book to read is on the shelf” (modifying the noun “book”).
When functioning as adverbs, infinitive phrases modify verbs, adjectives, or adverbs, expressing purpose, result, or reason. For example, “He studies hard to excel” (modifying the verb “studies”) or “She ran quickly to catch the bus” (modifying the adverb “quickly”).
Examples of Infinitive Phrases
Infinitive phrase examples are as follows:
infinitive Phrases as Nouns:
An infinitive, when used as a noun, is capable of performing any function that is typical of a noun, including that of a subject, direct object, object of a preposition, or subject complement. Here are several examples: Amber has the desire to uproot and move. The action of leaving one’s home serves as the direct object in this particular sentence.
Infinitive Phrases as Adjectives:
The infinitive phrase serves as the direct object of the verb intended when it works in this capacity. Before I can attend class, I need to finish writing a paper. The phrase “to do paper” acts as an adjective that modifies the noun “paper.” It was quite kind of Phil to offer to drive me around.
Infinitive Phrases as Adverbs:
A phrase that contains an infinitive as well as a modifier, object, complement, or actor is called an infinitive phrase. There might be more than one of them, and the phrase might not include all of them even if there are multiple. When employed as an adverb at the beginning of a sentence, infinitive phrases are the only phrases that need to be punctuated with a comma.
Placement and Position of Infinitive Phrases
Infinitive Phrases at the Beginning of Sentences:
- To improve her writing skills, she enrolled in a creative writing course. The infinitive phrase “To improve her writing skills” introduces the purpose or motivation behind her action.
- To save money, he decided to stop eating out. Here, the infinitive phrase “To save money” sets the context for his decision and explains the reason behind it.
Infinitive Phrases in the Middle of Sentences:
- She asked her friend to help her move the furniture. The infinitive phrase “to help her move the furniture” provides additional information about what her friend was asked to do.
- The student, eager to impress the professor, submitted a well-researched paper. The infinitive phrase “eager to impress the professor” describes the mindset or motivation of the student.
Infinitive Phrases at the End of Sentences:
- She went to the store to buy groceries. The infinitive phrase “to buy groceries” completes the purpose of her visit to the store.
- He needs to practice the piano more often to improve his skills. Here, the infinitive phrase “to improve his skills” indicates the intended outcome of increased practice.
Common Mistakes to Avoid with Infinitive Phrases
Splitting infinitives refers to placing an adverb or other word between the word “to” and the base form of a verb in an infinitive phrase. While some traditional grammar rules discourage splitting infinitives, it is widely accepted and commonly used in modern English. For example, the phrase “to boldly go” splits the infinitive “to go” with the adverb “boldly.” This construction is often employed for emphasis or stylistic purposes.
Confusing Infinitive Phrases with Prepositional Phrases:
Infinitive phrases, introduced by the word “to,” consist of an infinitive verb and its modifiers or complements. Prepositional phrases, on the other hand, begin with a preposition and include an object. The key distinction is that infinitive phrases include a verb, while prepositional phrases do not. Understanding the function of each type of phrase within a sentence can help differentiate between them and avoid confusion.
