Definition of Gerunds and Infinitives

Gerunds and infinitives are verb forms that function as nouns in English sentences, allowing us to express actions or states in various ways.

A gerund is the -ing form of a verb used as a noun (e.g., "Swimming is fun"). An infinitive is the base form of a verb preceded by "to" (e.g., "To swim is fun").
