Gerunds and Infinitives are two different forms of verbs.
Gerunds and infinitives are verbs that act like nouns. They can
be either the subject or the object of the sentence.
Look at this example:
The subject of this sentence is soccer, which is a noun. If the
subject is a verb, it can be a gerund or infinitive.
The verb play acts like a noun in these sentences, so it must be
a gerund or infinitive.
Subjects are usually at the beginning of the sentence. They
are the thing doing the action.
Gerund: Running is fun.
Infinitive: To run is fun.
It is better to use a gerund as the subject of the sentence. An
infinitive is very formal and does not sound very good in
When a verb is the object of the sentence it can be either a
gerund or infinitive. It can't be a base verb.
Gerund: Verb = Verb + ING
Infinitive: Verb + To + Verb
Deciding between a gerund and an infinitive as an object is
much more difficult than subjects. You must learn which
verbs are followed by gerunds, infinitives, or both.
The tables show which verbs are followed by gerunds and
which are followed by infinitives.
