Understanding Infinitives and Gerunds: Basic Definitions

What is an Infinitive?

The infinitive is the base form of a verb, usually preceded by the word “to.” It functions as a noun, adjective, or adverb within a sentence. Examples include:

• to run
• to eat
• to learn

Infinitives can express purpose, intention, or potential actions, and they are often used after certain verbs, adjectives, and nouns.

What is a Gerund?

A gerund is the -ing form of a verb that functions as a noun in a sentence. Unlike the infinitive, gerunds always end with “-ing” and can act as the subject, object, or complement. Examples include:

• Running is fun.
• I enjoy eating.
• Swimming helps build endurance.

Gerunds are versatile and frequently used after prepositions and certain verbs.
