Introduction
Should we say "I enjoy reading" or "I enjoy to read"? Is it correct to write "She stopped talking" or "She stopped to talk"? Interestingly, the last two sentences are both grammatically correct, but they do not mean the same thing.
Choosing between a gerund and an infinitive is one of the most challenging areas of English grammar. The difficulty arises because English does not have one rule that applies in every situation. Sometimes the word before the verb decides the form. Sometimes the structure of the sentence decides it. At other times, using a gerund instead of an infinitive changes the meaning completely.
This lesson explains:
• what gerunds, to-infinitives and bare infinitives are;
• the situations in which each form is used;
• verbs followed by gerunds or infinitives;
• verbs that take both forms with a change in meaning;
• important constructions such as used to, be used to, stop doing and stop to do;
• common errors made by students; and
• graded practice exercises with answers.
What Is a Gerund?
A gerund is the -ing form of a verb used as a noun.
Consider these examples:
• Reading improves our vocabulary.
• I enjoy reading.
• Her favourite activity is painting.
• He left without saying goodbye.
The words reading, painting and saying come from verbs, but in these sentences they perform functions normally performed by nouns. They are therefore gerunds.
Functions of a Gerund
Function | Example | Explanation |
Subject | Swimming is good exercise. | The activity is the subject. |
Object of a verb | I enjoy swimming. | It is the object of enjoy. |
Subject complement | My hobby is swimming. | It identifies the subject hobby. |
Object of a preposition | She is good at swimming. | It follows the preposition at. |

Gerund or Present Participle?
Both forms end in -ing, but their functions are different.
Sentence | Function of the -ing form |
Swimming is good exercise. | Gerund: it names an activity. |
I enjoy swimming. | Gerund: it is the object of enjoy. |
She is swimming. | Present participle: it forms the present continuous tense. |
The swimming child waved at us. | Present participle: it describes the child. |
The safest way to identify a gerund is to examine its function. If the -ing form names an action or activity and performs the work of a noun, it is a gerund.
What Is an Infinitive?
An infinitive is the basic form of a verb. It may be used with or without to.
The To-Infinitive
The to-infinitive has the structure:
KEY RULE: to + base form of the verb
Examples:
• to read
• to write
• to speak
• to understand
In sentences:
• I want to read this book.
• She decided to study harder.
• We hope to meet you soon.
• He went to the library to borrow a book.
The Bare Infinitive
A bare infinitive is the base form of a verb without to.
Examples:
• You should work hard.
• Let him speak.
• The teacher made us rewrite the answers.
• You had better leave now.
How Do We Decide Between a Gerund and an Infinitive?
Use te following questions as a practical decision method.
1. Is There a Preposition Before the Verb?
If there is a preposition immediately before the verb, normally use a gerund.
• She is interested in learning French.
• He left without speaking to me.
• They succeeded by working together.
• I am tired of waiting.
• We talked about visiting Jaipur.
The governing pattern is:
KEY RULE: preposition + gerund
2. Does the Action Express a Purpose?
Use a to-infinitive to explain why somebody does something.
• I went to the market to buy vegetables.
• She called me to discuss the problem.
• He studies hard to secure good marks.
• We use a thermometer to measure temperature.
The infinitive answers the question "Why?"
3. Is There a Modal Verb?
Use the bare infinitive after a modal verb.
• You must obey the rules.
• We should respect our elders.
• She can solve the problem.
• They might arrive late.
• You need not worry.
4. Does the First Verb Require a Fixed Pattern?
Many English verbs determine the form that follows them.
• I enjoy reading.
• I want to read.
• She avoided answering.
• She refused to answer.
These patterns must be learnt through repeated use.
5. Can Both Forms Be Used?
Some verbs accept both forms.
• It started raining.
• It started to rain.
With some verbs, the meaning remains almost unchanged. With others, choosing a gerund or infinitive changes the meaning significantly.

When Do We Use a Gerund?
1. As the Subject of a Sentence
A gerund is commonly used when a general activity is the subject.
• Reading develops the mind.
• Walking is good for health.
• Helping others gives us happiness.
• Learning a language requires patience.
A to-infinitive can also be used as a subject, especially in formal or literary statements:
• To forgive is divine.
• To make mistakes is human.
In ordinary English, however, a gerund often sounds more natural when discussing an activity in general.
2. After Certain Verbs
The following verbs are normally followed by a gerund.
Verb | Example |
admit | He admitted breaking the window. |
avoid | Avoid making unnecessary noise. |
consider | We are considering moving to Delhi. |
delay | Do not delay submitting the form. |
deny | She denied taking the money. |
dislike | I dislike waiting in long queues. |
enjoy | They enjoy playing chess. |
finish | Please finish writing the letter. |
imagine | Can you imagine living on the Moon? |
keep | He kept asking questions. |
mention | She mentioned meeting you. |
mind | Would you mind closing the window? |
miss | I miss talking to my old friends. |
postpone | They postponed holding the meeting. |
practise | Practise speaking English every day. |
recommend | I recommend reading this book. |
risk | You risk losing everything. |
suggest | She suggested taking a taxi. |
3. After Prepositions
• He is fond of reading.
• She is good at drawing.
• I am interested in learning Spanish.
• They left without informing us.
• We thanked her for helping us.
• After finishing the work, he went home.
Common combinations include:
• afraid of doing
• interested in doing
• good at doing
• tired of doing
• worried about doing
• responsible for doing
• capable of doing
• insist on doing
• think about doing
• succeed in doing
• apologise for doing
• prevent somebody from doing

4. When "To" Is a Preposition
The word to is not always an infinitive marker. In certain expressions, it is a preposition and must therefore be followed by a gerund.
Expression | Example |
look forward to | I look forward to meeting you. |
be used to | She is used to waking up early. |
get used to | You will get used to living here. |
object to | He objected to paying the fee. |
admit to | She admitted to telling a lie. |
be committed to | We are committed to helping the poor. |
devote oneself to | He devoted himself to teaching children. |
Compare:
• I want to learn English. Here, to learn is an infinitive.
• I am committed to learning English. Here, to is a preposition.
5. After Fixed Expressions
Use a gerund after these expressions:
Cannot help
• I cannot help laughing.
• She could not help crying.
It is no use/It is no good
• It is no use arguing with him.
• It is no good worrying about the past.
Be worth
• This book is worth reading.
• The place is worth visiting.
Have difficulty or trouble
• She had difficulty understanding the question.
• I have trouble remembering names.
Spend or waste time
• He spends hours watching television.
• Do not waste time complaining.
Be busy
• Mother is busy preparing dinner.
• They were busy decorating the hall.
How about/What about
• How about going for a walk?
• What about inviting Rohan?
There is no point in
• There is no point in blaming one another.
6. After "Go" for Recreational Activities
We frequently use go + gerund for leisure activities:
• go swimming
• go shopping
• go fishing
• go jogging
• go sightseeing
• go camping
• go cycling
Examples:
• We went shopping yesterday.
• They are going camping during the holidays.
When Do We Use a To-Infinitive?

Verb | Example |
agree | She agreed to help me. |
afford | We cannot afford to waste time. |
attempt | He attempted to escape. |
choose | She chose to remain silent. |

expect | We expect to receive the results soon. |
fail | He failed to notice the warning. |
hope | I hope to see you again. |
learn | She is learning to drive. |
manage | He managed to solve the puzzle. |
offer | I offered to carry her bag. |
plan | We plan to visit Kashmir. |

4. After Question Words
• I do not know what to say.
• Please tell me where to go.
• She explained how to operate the machine.
• We cannot decide which book to buy.
• Do you know when to begin?
We do not normally use why + to-infinitive. Instead, we say:
• Why should we do it?
• Why do it?
• Why not do it?
5. After "Too" and "Enough"
Too + adjective + to-infinitive
• The tea is too hot to drink.
• He is too weak to walk.
• The question was too difficult to answer.
Adjective + enough + to-infinitive
• She is old enough to travel alone.
• He was brave enough to admit his mistake.
• The room is large enough to accommodate everyone.
Enough + noun + to-infinitive
• We have enough food to feed everyone.
• She has enough experience to handle the situation.
6. After "The First", "The Last", "The Only" and Superlatives
• Riya was the first student to arrive.
• He was the last person to leave.
• She is the only person to understand me.
• This is the best place to relax.

Verb + Object + To-Infinitive
Certain verbs are followed by an object and then a to-infinitive.
KEY RULE: verb + person/object + to-infinitive
Verb | Example |
advise | The doctor advised me to rest. |
allow | They allowed us to enter. |
ask | She asked me to wait. |
encourage | The teacher encouraged us to participate. |
expect | I expect you to behave properly. |

remind | Please remind me to call him. |
teach | My father taught me to swim. |
tell | The teacher told us to remain quiet. |
want | I want you to complete the work. |
warn | They warned us not to touch the wire. |
Advise, Allow, Permit and Recommend
Some verbs can take a gerund when no person is mentioned, but an object + to-infinitive when a person is mentioned.
• The doctor advised resting for two days.
• The doctor advised me to rest for two days.
• The museum does not allow taking photographs.
• The museum does not allow visitors to take photographs.
With recommend, prefer these standard structures:
• I recommend reading this book.
• I recommend that you read this book.
Do not write: I recommend you to read this book.
With suggest, use a gerund or a that-clause:
• She suggested taking a taxi.
• She suggested that we take a taxi.
Do not write: She suggested us to take a taxi.
When Do We Use a Bare Infinitive?

• We should respect the rules.
2. After "Let" and "Make"

• You had better leave now.
• We had better inform the police.
• I would rather stay at home.
• She would rather walk than take a bus.
4. After "Why Not"
• Why not ask the teacher?
• Why not take a break?
5. After "Help"
Both forms are acceptable after help:
• She helped me complete the project.
• She helped me to complete the project.
6. After Verbs of Perception
After see, hear, watch, notice and feel, an object may be followed by a bare infinitive.
• I saw him cross the road.
• We heard the baby cry.
• She watched the bird fly away.
The bare infinitive usually presents the action as complete. The -ing form presents the action as being in progress.
• I saw him cross the road. I saw the complete action.
• I saw him crossing the road. I saw the action while it was happening.
In the passive, use a to-infinitive:
• He was seen to cross the road.
• The baby was heard to cry.
Advanced Gerund and Infinitive Forms
Form | Example |
Simple gerund | He enjoys teaching. |
Passive gerund | He dislikes being criticised. |
Perfect gerund | She admitted having made a mistake. |
Simple infinitive | She hopes to win. |
Passive infinitive | She expects to be selected. |
Perfect infinitive | He seems to have forgotten. |
Continuous infinitive | She appears to be sleeping. |
These forms help us express time and voice accurately:
• Nobody likes being ignored.
• He denied having stolen the money.
• She hopes to be invited.
• They appear to have completed the work.
• The children seem to be enjoying themselves.
