The Power of Infinitives

Understanding Infinitives

Infinitives are a type of verb that can function as a noun, adjective, or adverb in a sentence. They are formed by adding the word “to” before the base form of a verb. In this section, we will explore the definition and types of infinitives.

Definition

An infinitive is a verbal that is formed by adding “to” before a base form of a verb. It is considered a non-finite verb because it does not have a tense of its own. Infinitives can function as nouns, adjectives, or adverbs in a sentence.

Here are some examples of infinitives used as nouns:

• To swim is my favorite activity.
• To read is a great way to relax.
• To travel the world is my dream.

Infinitives can also be used as adjectives:

• I need a book to read.
• The best way to learn is by doing.
• He has a car to sell.

Finally, infinitives can be used as adverbs:

• I woke up early to study.
• She worked hard to finish the project.
• He exercises daily to stay healthy.

Types of Infinitives

There are four main types of infinitives: bare infinitives, full infinitives, split infinitives, and infinitive phrases.

1. Bare Infinitives: These are infinitives without the word “to”. They are used after modal verbs like can, could, may, might, shall, should, will, and would.

• She can swim.
• He should study more.

2. Full Infinitives: These are the most common type of infinitives. They are formed by adding “to” before the base form of a verb.

• I want to learn English.
• She needs to finish her homework.

3. Split Infinitives: These are infinitives where an adverb is placed between “to” and the base form of a verb.

• He decided to quickly finish the job.
• She needs to carefully read the instructions.

4. Infinitive Phrases: These are phrases that include an infinitive along with other words.

• To be or not to be, that is the question.
• I went to the store to buy some milk.

Usage of Infinitives

Infinitives are a versatile form of verbs that can be used in a variety of ways. They are formed by adding the word “to” before the base verb, and can function as nouns, adjectives, or adverbs. In this section, we’ll explore the different ways that infinitives can be used in a sentence.

Infinitives as Nouns

Infinitives can function as nouns in a sentence, either as the subject or the object of a verb. When used as a subject, the infinitive is often preceded by the word “it” or “there”. For example:

• It is important to exercise regularly.
• There are many places to visit in this city.

When used as an object, the infinitive is often preceded by a verb that indicates the action being performed. For example:

• She wants to learn how to play the guitar.
• He needs to finish his homework before he can go out.

Infinitives as Adjectives

Infinitives can also function as adjectives, describing or modifying a noun in a sentence. When used in this way, the infinitive is often placed immediately after the noun it is modifying. For example:

• I have a book to read tonight.
• The car to buy is the red one.

Infinitives as Adverbs

Finally, infinitives can function as adverbs, modifying a verb in a sentence. In this case, the infinitive is often used to indicate the purpose or reason for the action being performed. For example:

• She went to the store to buy some milk.
• He stayed up late to finish his project.

Common Mistakes with Infinitives

Split Infinitives

One of the most common mistakes with infinitives is the split infinitive. A split infinitive happens when an adverb is placed between the word “to” and the base verb. For example, “to boldly go” instead of “to go boldly.” While split infinitives have become more accepted in modern English, it is still best to avoid them in formal writing.

Dangling Infinitives

Another common mistake is the dangling infinitive. This happens when the subject of the sentence is not the same as the subject of the infinitive. For example, “To improve your writing, practice every day” is correct. However, “To improve your writing, every day should be practiced” is incorrect. The subject of the sentence should be the one doing the action in the infinitive.

It is important to remember that infinitives are not always necessary in a sentence. Sometimes, a simple gerund or a prepositional phrase can convey the same meaning without the risk of making a mistake.

Infinitives vs. Gerunds

If you’re learning English, you’ve probably come across infinitives and gerunds. These two verb forms can be a bit confusing, but once you get the hang of them, they can be a powerful tool in your language arsenal. In this section, we’ll go over the differences between infinitives and gerunds and give you some tips on how to use them correctly.

What are Gerunds?

Gerunds are verbs that end in “-ing” and function as nouns. For example, “running,” “eating,” and “sleeping” are all gerunds. Gerunds can be used in a variety of ways, such as:

• As the subject of a sentence: “Running is good exercise.”
• As the object of a verb: “I enjoy eating pizza.”
• After certain prepositions: “I’m thinking about going to the beach.”
• After certain verbs: “I started studying English last year.”

Differences between Infinitives and Gerunds

While infinitives and gerunds may have similar functions, there are some key differences between the two. Here are a few things to keep in mind:

• Infinitives are usually preceded by the word “to,” while gerunds end in “-ing.”
• Infinitives can function as nouns, adjectives, or adverbs, while gerunds always function as nouns.
• Infinitives are often used after certain verbs and adjectives, while gerunds are often used after certain prepositions and verbs.

Here are some examples to help illustrate the differences:

• “I want to learn English.” (Infinitive used as the object of a verb)
• “Learning English is fun.” (Gerund used as the subject of a sentence)
• “It’s important to exercise regularly.” (Infinitive used after an adjective)
• “I’m thinking about exercising more.” (Gerund used after a preposition)

Conclusion

Infinitives and gerunds are both important verb forms in English. By understanding the differences between the two, you can use them correctly in your writing and speaking. Remember that infinitives are usually preceded by “to” and can function as nouns, adjectives, or adverbs, while gerunds always end in “-ing” and function as nouns. With a little practice, you’ll be using them like a pro in no time!
