Both gerunds and infinitives are non-finite verb forms. That means their form does not change with a change in the subject or tense of the verb. A gerund is an –ing form that does the work of a noun. Examples are: cooking, singing, working, sleeping etc. Gerunds are often confused with present participles because they both look alike. However, they have different functions. Present participles function like adjectives. They are also used to form continuous verb forms.
Infinitives usually take the marking to. An infinitive can perform the same functions as a gerund. And in most cases, they are interchangeable.
In the following sentences, replace the gerund by an infinitive and an infinitive by a gerund.
