What is a Gerund?

• A gerund is the -ing form of a verb that functions as a noun in a sentence.

  • "She enjoys reading."
• Though it resembles a verb, a gerund operates like a noun.

Rules for Using Gerunds

1. Always ends in -ing.
2. Acts as a noun: Never functions as a verb.
3. Can be the subject or object in a sentence.
4. Certain verbs only take gerunds, not infinitives.
5. Prepositions require gerunds, not infinitives.
