Understanding Infinitives in English Grammar
Infinitives are a fundamental aspect of English grammar. They are formed using the base form of a verb preceded by "to" (e.g., "to run," "to eat"). Infinitives can function in various ways within a sentence, including as nouns, adjectives, and adverbs. Understanding how to use infinitives correctly will enhance your writing and speaking skills.
What is an Infinitive?
An infinitive is the base form of a verb preceded by "to," such as "to write," "to play," or "to study." Infinitives are versatile and can function as different parts of speech, depending on their role in the sentence. Unlike gerunds, which end in -ing, infinitives maintain their base verb form and are used to express actions or states without specifying tense.
Forms and Functions of Infinitives
Infinitives can take different forms and serve various functions in sentences. Here’s an overview of their primary uses:
Function | Example | Explanation |
---|---|---|
As the Subject | To travel is my dream. | The infinitive "to travel" acts as the subject of the sentence. |
As the Object | She wants to learn Spanish. | The infinitive "to learn" serves as the object of the verb "wants." |
As a Subject Complement | His goal is to become a doctor. | The infinitive "to become" functions as a complement to the subject "goal." |
As an Adjective | He has a book to read. | The infinitive "to read" describes the noun "book" and functions as an adjective. |
As an Adverb | She went to the store to buy groceries. | The infinitive "to buy" modifies the verb "went" and explains the purpose. |
Common Uses of Infinitives
Infinitives can be used in various contexts within sentences:
- As the Subject of a Sentence: Infinitives can act as the subject, as in "To run is healthy."
- As the Object of a Verb: They can function as the object, such as in "I want to eat pizza."
- As a Subject Complement: Infinitives can serve as complements, like in "Her dream is to become a writer."
- As an Adjective: Infinitives can describe nouns, e.g., "He has a plan to improve the project."
- As an Adverb: Infinitives can modify verbs, such as "She left early to avoid traffic."
Common Verbs Followed by Infinitives
Certain verbs are commonly followed by infinitives. These include verbs that express intention, desire, or plans. Here are some examples:
- Want: "I want to learn more about this topic."
- Need: "She needs to finish her assignment."
- Plan: "They plan to visit the museum."
- Decide: "He decided to take a break."
- Hope: "We hope to see you soon."
Infinitives vs. Gerunds
Both infinitives and gerunds can act as nouns, but they are used differently. Here’s a comparison:
Usage | Infinitive Example | Gerund Example | Explanation |
---|---|---|---|
Desire | She wants to travel. | She enjoys traveling. | Infinitives often express a specific desire or intention, while gerunds denote a general activity or habit. |
Purpose | He went to the store to buy milk. | He went to the store buying milk. | Infinitives often clarify the purpose or reason behind an action, whereas gerunds describe the action itself. |
Preference | She prefers to read rather than watch TV. | She prefers reading to watching TV. | Both forms are used to express preferences, but infinitives often highlight intention while gerunds emphasize the activity. |
Common Mistakes with Infinitives
Here are some common mistakes to avoid when using infinitives:
- Incorrect Verb Following: Some verbs are mistakenly followed by gerunds instead of infinitives. For instance, use "want to" instead of "want doing."
- Confusing Infinitives with Gerunds: Ensure you use infinitives where intended, as in "I hope to see you" vs. "I hope seeing you."
- Incorrect Placement: Infinitives should be placed correctly within sentences, such as "She plans to visit her grandmother" rather than "She plans visiting her grandmother."

Infinitives are a crucial part of English grammar, providing flexibility in sentence construction. Understanding their various uses and common mistakes will enhance your ability to communicate effectively.
