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.

How do we know if we need a gerund or an infinitive?
Sometimes it is confusing to know whether we need an gerund or an infinitive. Much of the time, other than the rules mentioned here, there is little way to know. If you are a native speaker, you know what sound correct. If you are learning English, you often need to simply memorize which verbs take a gerund and which verbs take an infinitive. With practice, you will eventually know which one “sounds right.” There are a few rules which may help you some of the time.
Gerunds are often used when the action in the main verb and the gerund happen at the same time.
Gerunds are also often used in verbs that express likes and dislikes such as: like, love, enjoy, dislike, and hate.
We often use infinitives when the action in the infinitive follows the action in the main verb.
Sometimes we use infinitives to refer to a future event.
