Click each section below to review the grammar explanation and examples.
A Structure and Sample Paragraph

An infinitive is the base form of a verb with to, such as to study or to travel. A gerund is a verb ending in -ing that functions as a noun, such as studying or travelling. Some verbs are always followed by an infinitive, some are always followed by a gerund, and a few can be followed by either one. Learning these verb patterns will help you speak and write more naturally.

Verb + To + Base Verb

Verb + Verb-ing
Sample Paragraph

Maria decided to apply for a new job because she wanted to improve her career. She also enjoys meeting new people and practises speaking English every day to become more confident.

Tip: Different verbs require different patterns. Some verbs are followed by an infinitive.

I want to learn English.
She decided to stay home.

Other verbs are followed by a gerund.

We enjoy playing soccer.
They finished cleaning the kitchen.

I want learning English.
She decided staying home.
We enjoy to play soccer.
They finished to clean the kitchen.

Remember: Some verbs are followed by to + verb, while others are followed by verb + -ing. You must learn which pattern each verb uses.

B Common Infinitive Verbs

Many English verbs are followed by an infinitive (to + base verb). After these verbs, do not use a gerund. Learning these common patterns will make your speaking and writing much more natural.

Remember: After these verbs, always use to + base verb.

C Common Gerund Verbs

Many English verbs are followed by a gerund (verb + -ing). After these verbs, do not use an infinitive. Learning these common verb patterns will help you avoid one of the most common grammar mistakes made by English learners.

  • The manager suggested changing the schedule.
  • I don't mind waiting a few more minutes.
  • She admitted making a mistake.
  • They postponed moving to a new house.

She finished to clean the kitchen.
They suggested to take the bus.

Remember: After these verbs, always use verb + -ing.

D Infinitive or Gerund Verbs

Some English verbs can be followed by either an infinitive (to + verb) or a gerund (verb + -ing). For many of these verbs, the meaning stays the same. However, with a few common verbs, the meaning changes depending on which form you use. Learning these differences will help you understand native speakers and avoid common grammar mistakes.

Verb + To + Verb

Verb + Verb-ing
VerbMeaning
beginBoth forms are correct.
continueBoth forms are correct.
likeBoth forms are correct.
loveBoth forms are correct.
hateBoth forms are correct.
preferBoth forms are correct.
startBoth forms are correct.
stopThe meaning changes.
rememberThe meaning changes.
forgetThe meaning changes.
tryThe meaning changes.
Examples
  • She began studying at eight o'clock.
  • She began to study at eight o'clock.
  • I like reading before bed.
  • I like to read before bed.
  • He stopped smoking. (He quit smoking.)
  • He stopped to smoke. (He stopped another activity so he could smoke.)
  • Please remember to lock the door. (Don't forget to do it.)
  • I remember locking the door. (I have a memory of doing it.)
  • She tried calling him. (She tested one possible solution.)
  • She tried to call him. (She attempted to call him.)

Tip: Many verbs can take both forms, but they do not always mean the same thing.

The most important verbs to remember are:

stop
remember
forget
try

These verbs often appear in English tests because the meaning changes depending on whether you use an gerund or an infinitive.

I remember meeting her.
Please remember to call me.
He stopped working at six.

These forms are not always interchangeable.

Always think about the meaning, not only the grammar.

E Verb + Object + Infinitive / Gerund

Some English verbs are followed by an object before another verb. These verbs often use either an infinitive (to + verb) or a gerund (verb + -ing). Learning these patterns will help you give instructions, make requests, and describe actions more naturally.

Verb + Object + To + Base Verb

Verb + Object + From + Verb-ing
PatternCommon Verbs
Verb + Object + To + Verbadvise, ask, encourage, expect, force, help, invite, order, persuade, remind, teach, tell, want, warn
Verb + Object + From + Verb-ingprevent, stop, discourage, protect
Examples
  • The teacher encouraged the students to practise every day.
  • My friend reminded me to bring my passport.
  • The manager asked us to arrive early.
  • Our parents taught us to be responsible.
  • The doctor advised him to exercise regularly.
  • Heavy rain prevented the workers from finishing the project.
  • The police stopped the driver from speeding.
  • Good planning protected the company from losing money.
  • His parents discouraged him from quitting school.
  • The coach persuaded the team to keep trying.

Tip: Many verbs that involve giving advice, instructions, or requests use this pattern:

Verb + Object + To + Base Verb

However, verbs such as prevent, stop, discourage, and protect usually use:

Verb + Object + From + Verb-ing

The teacher told us to study.
My mother reminded me to call.
The fence prevented the dog from escaping.

The teacher told us studying.
My mother reminded me calling.
The fence prevented the dog to escape.

Remember: Use Verb + Object + To + Base Verb for advice, requests, and instructions.

Use Verb + Object + From + Verb-ing after prevent, stop, discourage, and protect.

F Verbs Without "To"

Some English verbs are followed directly by the base form of another verb without to. These include modal verbs, some causative verbs, and certain verbs of perception. Learning these patterns will help you avoid one of the most common grammar mistakes made by English learners.

Modal Verb + Base Verb

Let / Make + Object + Base Verb

Help + Object + (To) Base Verb

See / Hear / Watch + Object + Base Verb
PatternExamples
Modal + Base Verbcan, could, may, might, must, shall, should, will, would
Let + Object + Base Verblet him go, let us leave
Make + Object + Base Verbmake them clean, make her apologize
Help + Object + (To) Base Verbhelp me carry, help me to carry
See / Hear / Watch + Object + Base Verbsee him leave, hear them sing, watch her dance
Examples
  • You must wear a seatbelt.
  • We can finish the project today.
  • My parents let me stay up late on weekends.
  • The teacher made the students rewrite the assignment.
  • My friend helped me carry the heavy boxes.
  • My friend helped me to carry the heavy boxes.
  • I saw the children play in the park.
  • We heard someone knock on the door.
  • She watched the birds fly across the lake.
  • They would accept the offer if the conditions improved.

Tip: After modal verbs (can, could, may, might, must, should, will, would), always use the base form of the verb.

After let and make, also use the base form without to.

After help, both forms are correct:
help someone carry
help someone to carry

After see, hear, and watch, use the base form to describe a complete action.

She can drive.
They made us wait.
I heard him sing.

She can to drive.
They made us to wait.
I heard him to sing.

Remember: Most verbs are followed by to + verb or verb + -ing, but modal verbs, let, make, and many verbs of perception are followed directly by the base form of the verb.

G Key Points to Remember

Infinitives and gerunds are common in everyday English. Some verbs are followed by to + base verb, others are followed by verb + -ing, and a few can use both forms. Learning these patterns will help you communicate more accurately and confidently in speaking and writing.

Remember these key patterns:

Verb + To + Base Verb
want to learn

Verb + Verb-ing
enjoy reading

Verb + To + Verb / Verb-ing
begin to study / begin studying

Verb + Object + To + Base Verb
tell someone to wait

Verb + Object + From + Verb-ing
prevent someone from leaving

Modal Verb + Base Verb
can drive
Key Ideas
  • Many verbs are always followed by to + base verb.
  • Many other verbs are always followed by verb + -ing.
  • Some verbs, such as begin, continue, like, and start, can use either form.
  • Some verbs, including stop, remember, forget, and try, change meaning depending on whether they are followed by an infinitive or a gerund.
  • Many verbs followed by an object use to + base verb, such as tell, ask, advise, and encourage.
  • After prevent, stop, discourage, and protect, use from + verb-ing.
  • After modal verbs, let, and make, use the base form without to.
Quick Examples
  • She decided to apply for the position.
  • We enjoy travelling together.
  • They started working early.
  • He remembered to lock the door.
  • I remember locking the door.
  • The teacher asked us to finish the assignment.
  • The heavy rain prevented us from leaving.
  • You must wear your seatbelt.

Final Tip: Before choosing a verb pattern, ask yourself these questions:

1. Does this verb take an infinitive? Use Verb + To + Base Verb.

2. Does this verb take a gerund? Use Verb + Verb-ing.

3. Can this verb use both forms? Check whether the meaning stays the same or changes.

4. Is there an object before the second verb? Use Verb + Object + To + Base Verb or Verb + Object + From + Verb-ing.

5. Is the first verb a modal verb, let, or make? Use the base form without to.

The easiest way to master infinitives and gerunds is to learn the verb patterns, not individual grammar rules. The more common verb patterns you remember, the more natural, accurate, and confident your English will become.
