Gerunds and infinitives are both verb forms that can be used as subjects, objects, or complements in sentences. Gerunds are formed with "-ing" and act as nouns. Infinitives use "to" before the base verb form. Some verbs are followed by gerunds as objects, while others require infinitives. There are also cases where gerunds and infinitives can be interchangeable with little difference in meaning. Proper use depends on the specific verb and intended nuance. Both forms can take different tenses and voices.

1. GERUND
VS
INFINITIVE

2. GERUNDS
 A gerund is a noun made from a verb by
adding "-ing." You can use a gerund as
the subject, the complement, or the
object of a sentence.

3. EXAMPLES
Reading helps you learn English. subject
of sentence
Her favorite hobby is reading. complement
of sentence
I enjoy reading. object of sentence

4.  Gerunds can be made negative by
adding "not.“
Examples:
He enjoys not working.
The best thing for your health is not
smoking.

5. INFINITIVES
 Infinitives are the "to" form of the verb.
You can also use an infinitive as the
subject, the complement, or the object of
a sentence.

6. EXAMPLES
To learn is important. subject of sentence
The most important thing is to
learn. complement of sentence
He wants to learn. object of sentence

7.  Infinitives can be made negative by
adding "not.“
Examples:
I decided not to go.
The most important thing is not to give up.

8. Both Gerunds &
Infinitives
 can be used as the subject or the complement
of a sentence. However, as subjects or
complements, gerunds usually sound more like
normal, spoken English, whereas infinitives
sound more abstract. In the following
sentences, gerunds sound more natural and
would be more common in everyday English.
Infinitives emphasize the possibility or potential
for something and sound more philosophical. If
this sounds confusing, just remember that 90%
of the time, you will use a gerund as the
subject or complement of a sentence.

9. EXAMPLES
 Learning is important. normal subject
 To learn is important. abstract subject less common
 The most important thing
is learning. normal complement
 The most important thing is to
learn. abstract complement - less
common

10. As the object of the
sentence…
 It is more difficult to choose between a gerund
or an infinitive. In such situations, gerunds and
infinitives are not normally interchangeable.
Usually, the main verb in the sentence
determines whether you use a gerund or an
infinitive.
Examples:
He enjoys swimming. "Enjoy" requires a
gerund.
He wants to swim. "Want" requires an
infinitive.

13.  Gerunds can often be modified with
possessive forms such as his, her, its,
your, their, our, John's, Mary's, the
machine's, and so on. This makes it
clearer who or what is performing the
action.

said no.

18. Some verbs can be followed by a
gerund or an infinitive with little
difference in meaning…
can’t bear continue like prefer
can’t stand hate
love propose
 The difference in meaning is small with these particular verbs, and
gerunds and infinitives can often be used interchangeably, but using a
gerund suggests that you are referring to real activities or experiences.
Using an infinitive suggests that you are talking about potential or
possible activities or experiences.
Examples:
The British reporter likes living in New York. He lives in New York and
he likes what he experiences there.
The British reporter likes to live in New York whenever he works in the
