Gerund or Infinitive? How English Picks -ing or to

The first verb chooses the form that follows it. Learn the verbs that demand -ing, the ones that take to, and the four that change their meaning.

The first verb chooses the form that follows it. Learn the verbs that demand -ing, the ones that take to, and the four that change their meaning.

The first verb decides the shape of the second. You say I enjoy swimming, but I want to swim. Saying I enjoy to swim sounds jarring immediately, even though your listener understands what you mean. Everything on this page follows from that single partnership.

There is no hidden logic that explains why enjoy demands -ing while hope takes to. Stop searching for a rule you can reason out, because it does not exist. Your job is to learn each verb together with the partner form it requires [1].

Learn the verb and partner together

Grammar guides often claim that -ing describes real experiences while to describes future goals. That rule sounds neat in theory, but it collapses in real speech.

Consider admit and agree. Both report statements, yet you say He admitted taking the file and He agreed to take the file. Finish and decide split the same way: I finished writing, but I decided to write. The verb alone makes the choice.

Treat the combination as one vocabulary item. When you record a verb, store it attached to its required partner: avoid doing, decide to do, mind doing, plan to do. This habit removes hesitation when you speak [2].

  • She decided to accept the offer. The verb decide always takes a to-infinitive.
  • She avoided answering the question. The verb avoid always requires the -ing form.
  • They promised to arrive on time. The verb promise takes a to-infinitive.
  • They finished cleaning the kitchen. The verb finish takes an -ing form.

One sentence, two verbs

When a sentence contains two verbs, each performs a distinct job. The first verb is finite. It carries the tense and agrees with the subject.

The second verb is non-finite. Functioning as the object of the first verb, it never changes for tense, person or time.

Same subject, same second verb, five first verbs. Watch what each one forces.

She decided to call her manager.

Decide takes to + base form. Nothing about the meaning tells you this; the verb simply carries the pattern.

She avoided calling her manager.

Avoid takes -ing. Swap them and She avoided to call is wrong, even though the meaning is clear.

She started to call her manager.

Start takes either, with no change in meaning. She started calling says the same thing.

She stopped to call her manager.

Here the meaning moves. Stop to do means she paused in order to make the call.

She stopped calling her manager.

Stop doing means the calls ended. Same two words, opposite event.

first verbto-infinitive-ing form

Notice what happens if you shift the tense: She decides to call her manager. The first verb changes, but to call remains untouched. The same rule applies to verbs that demand -ing: She enjoyed meeting her manager becomes She enjoys meeting her manager. The second verb never carries tense.

Fourteen verbs that choose only one form

A small group of everyday verbs accounts for most errors with -ing and to. Commit fourteen core verbs to memory with their partners to eliminate most mistakes in daily conversation [3].

Seven frequent verbs demand an -ing form: enjoy, finish, avoid, mind, suggest, keep and practise. Seven demand a to-infinitive: want, decide, hope, plan, need, promise and offer.

VerbRequiresNatural example
enjoy, finish, avoid-ingI enjoy cooking, we finished reviewing, he avoided answering.
mind, suggest-ingDo you mind waiting outside? She suggested taking a taxi.
keep, practise-ingWhy do you keep interrupting? Practise speaking daily.
want, decide, hopetoWe want to hire someone, they decided to stay, I hope to see you.
plan, needtoShe plans to study law, you need to submit today.
promise, offertoHe promised to call, they offered to help us move.

Notice how mind works in requests: Would you mind closing the window?, I do not mind waiting. English always requires -ing after mind. With keep, the -ing form means continuing an action repeatedly: Why do you keep checking your phone?.

Every preposition takes -ing

Prepositions follow an absolute rule with zero exceptions. Whenever a verb immediately follows a preposition, that verb must take the -ing form.

This rule applies to prepositions like about, at, by, for, in, of and without: She is good at explaining ideas, Thank you for coming, He left without saying goodbye. Spot the preposition and the choice is settled.

RuleAny verb that immediately follows a preposition must take the -ing form, even when that preposition is the word to.

The main trap is the word to. Usually to marks an infinitive, but it can also be a preposition linking a verb to an object. When to is a preposition, the following verb takes -ing.

Look at look forward to: you say I look forward to meeting you, not I look forward to meet you. The same pattern governs be used to and object to: I am used to waking up early, They objected to paying. If you can replace the verb with it, to is a preposition: I look forward to it, so I look forward to seeing it.

Verbs that accept both forms

Several common verbs accept both -ing and to. With some, the meaning stays identical; with others, picking the wrong form changes your whole story.

Three verbs take both forms with no change in meaning: start, begin and continue. You can say It started raining or It started to rain, communicating the exact same idea. Native speakers use both freely, avoiding awkward double -ing phrases like is starting raining.

Four verbs change meaning completely: remember, forget, stop and try.

VerbWith -ingWith to
rememberA past memory: I remember locking the door.A duty: Remember to lock the door.
forgetRecall past event: I will never forget seeing Rome.Fail a task: Do not forget to buy milk.
stopQuit a habit: He stopped smoking.Pause to do something: He stopped to smoke.
tryExperiment with a method: Try resetting the router.Make an effort: Try to open the door.

Notice the pattern: -ing points backward at an action already experienced, while to points forward toward an intention or duty. Keeping that timeline in mind makes the choice intuitive.

Adding an object before the infinitive

When you want another person to act, English places them between the first verb and the to-infinitive: verb plus object plus to. Common verbs with this pattern include ask, tell, want, need, remind, advise and expect.

  • Ask her to come to the meeting. A polite request for someone else to act.
  • Tell him to wait in the lobby. A direct instruction.
  • I want you to check these figures. Expressing an expectation from someone else.
  • Please remind me to call the bank. Prompting another person to trigger your future action.
  • The lawyer advised them not to sign. A recommendation, with not before to.

Notice where the negative sits: place not directly before to: She told me not to worry. Beware of literal translations from languages that insert "that": never say I want that you come. Always say I want you to come.

Four mistakes worth fixing first

These four mistakes appear regularly in spoken and written English past the beginner stage. Each error sounds awkward to native ears, and each one is quick to fix.

  1. "I enjoy to read novels." The verb enjoy never takes a to-infinitive. Always pair it with an -ing form: I enjoy reading novels. For an infinitive, use like: I like to read novels.
  2. "I am looking forward to hear from you." The word to is a preposition here, and every preposition requires an -ing form. Say I am looking forward to hearing from you.
  3. "She suggested to go home." The verb suggest cannot take a to-infinitive. Say She suggested going home, or use a clause: She suggested that we go home.
  4. Saying "I stopped to eat junk food" when quitting. Using stopped to eat means you paused in order to eat junk food. When you quit a habit, use -ing: I stopped eating junk food.

The third mistake catches almost every learner. Verbs of suggestion reject the infinitive. To name the person, always use a that-clause: He suggested that I apply.

Writing looking forward to hear from you marks non-native business emails immediately. Switching to -ing takes one second and makes your writing sound professional.

Conclusion

The choice between -ing and a to-infinitive is not a puzzle of abstract rules. The first verb dictates what follows, prepositions always demand -ing, and four verbs change their meaning depending on which partner you choose. When you learn each verb attached to its partner, hesitation disappears. Practise these pairs aloud, and the correct patterns become an automatic reflex.

Frequently asked questions

Is there a general rule to know whether a verb takes -ing or to?

No single rule exists. While -ing often connects to ongoing actions and to points toward goals, common verbs break this pattern. The only reliable strategy is to learn each verb together with the partner form it requires.

Why do we say "look forward to seeing" instead of "look forward to see"?

Here, to is a preposition, not part of an infinitive. Prepositions in English are always followed by nouns or -ing forms. Because to functions as a preposition here, it requires the -ing form: looking forward to hearing, seeing, or meeting.

What is the difference between "stopped smoking" and "stopped to smoke"?

Stopped smoking means quitting the habit permanently. Stopped to smoke means pausing your activity at that moment in order to smoke a cigarette. The to-infinitive expresses the purpose of stopping.

Can I use "suggest to do" if I name a person?

No. Suggest cannot take an infinitive even with an object. Saying "He suggested me to go" is incorrect. Say "He suggested going" or "He suggested that I go".
