Gerunds and infinitives look like verbs, but they are used in sentences as nouns. A gerund is the “ing” form of the verb. An infinitive is the word “to” plus the base form of the verb. For example, you have probably seen signs on the street that say “No Parking.” The word “Parking” looks like the present continuous of the verb “park.” However, “Parking” is a noun in this case.
Gerunds and infinitives can be used as subjects of a sentence, or as objects. In this posting I show you how to use gerunds and infinitives. There will be many example sentences. The download at the end will contain a list of verbs that are followed by either a gerund or an infinitive when used as an object.
