Gerund and Infinitive

⮚ A gerund is a noun made from a verb by adding "-ing."

⮚ Infinitives are the "to" form of the verb.

⮚ It can be tricky to remember which verbs are followed by the infinitive (the to form) of the verb and which are followed by the gerund (the ing form) of the verb.

Try to remember that:

Gerunds are often used when actions are real, fixed, or completed. "I enjoy cooking."

Infinitives are often used when actions are unreal, abstract, or future: "He wants to swim."

Fill in the blanks with the infinitives or Gerunds:

1. We decided …….(buy) a new car.
