Gerunds and Infinitives

Gerunds and Infinitives: verb forms used as another part of speech

A gerund has an -ing form and looks like a verb but acts like a noun.

Reading is fun.

  • A gerund may be replaced with a single noun or pronoun and still make sense.

    For example: It is fun.

I enjoy gardening.
  • A gerund functions just like a noun in this sentence.

    Gardening is the object of the verb enjoy.

An infinitive is a verb form (to be, to go, etc.) which can act as a noun, adjective, or adverb.

  1. I want to eat. (noun)
  2. I have a list of groceries to buy. (adjective)
  3. The homework was difficult to finish. (adverb)

You may delete the “to” of the infinitive after these verbs:

  • hear
  • help
  • let
  • make
  • please
  • see
  • watch

For example: My teacher helps me (to) learn infinitives.
