Main Difference – Infinitive vs Gerund
Many English learners find it difficult to choose between the use of infinitive and gerund. In this article, we are going to explain the use and role of infinitive and gerund. The main difference between Infinitive and Gerund is, the infinitive often takes the base form of a verb while the gerund is a verb in its –ing form.
What is an Infinitive
The infinitive can be introduced as a verb-noun. Though it does not act as the verb of a sentence, it has certain qualities of a verb. An infinitive can act as the object, the subject or the complement. It is not limited by person or number as a finite verb. The example below will throw light into these characteristics.
He always helps people.
He always tries to help people.
In the first example, helps has he for its subject; hence the verb like is limited by person and number. It is called the finite verb.
In the second example, to help simply names the action denoted by the verb try and is used without mentioning any subject. It is, therefore, not limited by a person and number as a verb that has a subject.
The preposition to is frequently used with the infinitive, but this does not mean that it is an essential part or sign of it.

What is a Gerund
A gerund is a form of a verb which ends in –ing, and has the force of a noun and a verb. Therefore, it is a verb-noun that can act as either the subject or the object of a verb. A gerund can indicate an action or a state of being and any action verb can be made into a gerund.
Uses of the Gerund
A gerund can be used,
As a subject of a verb

He taught me swimming.
He taught me to swim.
Giving is better than receiving.
To give is better than to receive.
It is important to remember that the use of an infinitive or a gerund depends on the main verb.
