In the journey of mastering any language, understanding verb structures is crucial. One such fundamental structure is the verb infinitive. Though it may sound like a complex grammatical term, the concept is straightforward and essential for building a strong foundation in language learning. This article aims to provide a comprehensive guide on verb infinitives, highlighting their importance, usage, and various forms.
What is a Verb Infinitive?
A verb infinitive is the base form of a verb, often preceded by the word “to.” It is the form you would find in a dictionary. For example, in English, the infinitive form of the verb “run” is “to run.” Unlike conjugated verbs, infinitives are not bound by tense, number, or mood, making them versatile building blocks for sentences.
Basic Structure
In English, the most common structure of an infinitive is “to” followed by the verb. Examples include:
– To eat
– To sleep
– To write
However, it’s important to note that not all infinitives include “to.” These are known as “bare infinitives,” and they often appear after certain auxiliary verbs such as “can,” “must,” and “should.” For example:
– I can swim.
– She must leave.
– They should wait.
Types of Infinitives
Infinitives can be classified into different types based on their usage and form. Understanding these can help you use them more effectively in various contexts.
Full Infinitive
The full infinitive, also known as the “to-infinitive,” is the most common form. It consists of “to” followed by the base form of the verb. This form is used in a variety of grammatical structures, including:
– As the subject of a sentence: To read is enjoyable.
– As the object of a verb: I want to learn.
– After adjectives: It is important to stay hydrated.
Bare Infinitive
The bare infinitive is the base form of the verb without “to.” It is often used:
– After modal verbs: You should go.
– After certain verbs of perception like see, hear, feel: I saw him run.
– After let, make, and help: Let him try.
Functions of Infinitives
Infinitives serve various functions in a sentence, making them incredibly versatile. Here are some key roles they play:
Infinitives as Subjects
Infinitives can act as the subject of a sentence. For instance:
– To travel is my dream.
– To succeed requires hard work.
In these sentences, the infinitive phrase “to travel” and “to succeed” serve as the subjects, explaining what the sentence is about.
Infinitives as Objects
Infinitives can also function as objects of verbs, providing additional information about the action. For example:
– I hope to visit Japan.
– She plans to start a business.
Here, “to visit” and “to start” are objects of the verbs “hope” and “plans,” respectively.
Infinitives after Adjectives
Infinitives often appear after adjectives to provide further explanation or context. Examples include:
– It is easy to understand.
– She is excited to join.
In these cases, the infinitives “to understand” and “to join” clarify the adjectives “easy” and “excited.”
Infinitives to Express Purpose
Infinitives can be used to express the purpose of an action. For example:
– He went to the store to buy milk.
– She studied hard to pass the exam.
In these sentences, the infinitives “to buy” and “to pass” explain the reason behind the actions.
Common Mistakes and How to Avoid Them
Understanding infinitives is one thing, but using them correctly can be challenging. Here are some common mistakes and tips on how to avoid them:
Splitting Infinitives
One of the most debated topics in grammar is the “split infinitive,” where an adverb is placed between “to” and the verb. For example:
– To boldly go where no man has gone before.
While traditionalists argue against splitting infinitives, modern usage often accepts it for the sake of clarity or emphasis. The key is to be consistent and clear in your writing.
Confusing Gerunds and Infinitives
Another common mistake is confusing gerunds (verb + ing) with infinitives. While both can function as subjects or objects, their usage depends on the context and the main verb. For example:
– I enjoy swimming. (Correct: gerund as object)
– I want to swim. (Correct: infinitive as object)
– I enjoy to swim. (Incorrect)
Overusing Infinitives
While infinitives are versatile, overusing them can make your writing repetitive and monotonous. Mix up your sentence structures by incorporating different verb forms and clauses.
Advanced Usage of Infinitives
Once you’re comfortable with basic infinitive forms and functions, you can explore more advanced usages that add depth and variety to your language skills.
Infinitive Phrases
An infinitive phrase includes the infinitive verb and any complements or modifiers. For example:
– To win the game, you need to practice hard.
– She decided to leave early to avoid traffic.
In these sentences, “to win the game” and “to avoid traffic” are infinitive phrases that provide additional context or information.
Perfect Infinitives
The perfect infinitive form is used to express actions that occurred before the action of the main verb. It consists of “to have” followed by the past participle of the verb. For example:
– She claims to have seen the movie.
– He appears to have forgotten the meeting.
Here, “to have seen” and “to have forgotten” indicate actions that happened prior to the main verbs “claims” and “appears.”
Passive Infinitives
Passive infinitives are used to emphasize the action rather than the subject performing the action. They are formed with “to be” followed by the past participle of the verb. For example:
– The book is to be returned by Friday.
– The project needs to be completed soon.
In these sentences, “to be returned” and “to be completed” focus on the actions rather than who is performing them.
Infinitives in Different Languages
While this article primarily focuses on English, it’s worth noting that infinitives exist in many other languages, albeit with different structures and rules. Understanding how infinitives work in other languages can enrich your overall language learning experience.
Spanish Infinitives
In Spanish, infinitives end in -ar, -er, or -ir. Examples include:
– Hablar (to speak)
– Comer (to eat)
– Vivir (to live)
Similar to English, Spanish infinitives can function as subjects, objects, and express purpose. For example:

– Ich möchte essen. (I want to eat.)
Practical Tips for Mastering Infinitives
