With remember, stop and regret, an -ing form and a to-infinitive can express different meanings. Compare I remember posting the letter, a recollection, with I remembered to post the letter, remembering a task and doing it. The whole verb pattern matters. An -ing form can head a clause with a noun-like role, while a to-infinitive uses to followed by the plain verb form.
Compare I stopped speaking with I stopped to speak. The first says that the speaking ended; the second says that another activity stopped so that speaking could take place. Neither construction alone tells you whether an activity was given up permanently. Interpret the verb pattern with its tense and context.
How parts of speech frame gerunds and infinitives
Traditional grammar calls an -ing form in a noun-like role a gerund. In Swimming helps me relax, the -ing clause is the subject, but it retains verbal properties: Swimming slowly helps me relax includes an adverb. To swim every day takes commitment has an infinitive clause as subject. Sentence function and word form are related, but are not the same label.
In She quickly remembered to lock the door, quickly modifies remembered and the infinitive identifies the task. In She remembered locking the door, the -ing clause identifies the remembered event. The difference between I regret telling him and I regret to tell you comes from the verb pattern and context, not from the choice of object pronoun.
Remember: memory of a past action versus obligation for a future action
Remember followed by a gerund refers to a memory of something that already happened. “I remember meeting her at the conference” means the meeting happened in the past, and the speaker has a memory of it now. Remember followed by an infinitive points forward to something the speaker must not forget to do. “Remember to send the invoice” means the sending should happen after the reminder. This is one of the clearest meaning shifts in English grammar, and it appears constantly in spoken and written communication.
Use the tense as well as the following form. Remember to call is a reminder about a task. I remembered to call normally reports that the speaker remembered the task and made the call. I remember calling reports a memory of making a call. An infinitive after remember does not make every sentence refer to an action that is still pending.
Stop: ending an activity versus pausing one activity to begin another
Stop + -ing identifies the activity that ends: He stopped drinking coffee when the phone rang describes an interruption. He stopped drinking coffee years ago can describe giving up a habit. He stopped to drink coffee instead gives the purpose of stopping another activity.
The tourists stopped taking photos says that the photo-taking ended at that point. The tourists stopped to take photos gives a reason for their pause. The surrounding context can say what they paused and whether they resumed it. The grammar itself does not guarantee a permanent change.
Regret: sorrow about a completed action versus politeness before bad news
Regret followed by a gerund expresses sorrow about something that has already happened. “She regrets leaving the company” means the departure occurred and she feels sorry about it now. Regret followed by an infinitive is commonly used to announce unwelcome information politely: “We regret to inform you that your application was unsuccessful.” In that structure, the regrettable act is the act of informing, which is happening at that moment. The tone is formal and often institutional.
Regret + -ing can describe an earlier action or a situation someone is sorry about: I regret missing your call and I regret living so far away. The second situation may still continue. Regret to inform/say/announce is a formal way to introduce unwelcome information; do not extend that formula mechanically to every verb.
Common patterns across verbs and the parts-of-speech hub
Remember, stop, and regret are the classic examples, but they belong to a wider network of verb-complement patterns. Some verbs are usually followed by gerunds, such as avoid, consider, and suggest. Others commonly take infinitives, such as decide, hope, and plan. A smaller set can take both, sometimes with little difference, as with begin or start, and sometimes with a major meaning shift, as with the three verbs in this article. This is where a parts-of-speech hub becomes useful: understanding verbs requires links to nouns as objects, adjectives in complement structures, adverbs marking time and manner, prepositions introducing gerund phrases, and conjunctions connecting clauses.
| Verb pattern | Meaning with gerund | Meaning with infinitive | Example pair |
|---|---|---|---|
| remember | memory of a past action | remember a task before doing it; tense varies | “I remember locking it” / “Remember to lock it” |
| stop | end an activity | pause in order to act | “She stopped reading” / “She stopped to read the sign” |
| regret | feel sorry about an action or situation | announce bad news politely | “He regrets selling it” / “We regret to announce…” |
If you are building a strong grammar foundation, study these patterns alongside related topics: what verbs are, how direct objects work, when prepositions require gerunds, how clauses differ from phrases, and why modifiers change emphasis. Those linked ideas form the real structure of parts of speech. Grammar is not a stack of disconnected rules. It is a system in which word class, syntax, and meaning interact at every step.
How to choose correctly in real writing and speech
Check each verb separately. Ask whether remember refers to a recollection or remembering a task, whether stop names the ended activity or its purpose, and whether regret expresses sorrow about an action or introduces unwelcome information. This is a practice method, not a proven fastest strategy. See the British Council explanation and the Cambridge verb-pattern guide.
Paraphrase the examples before choosing a form: remember doing means having a memory; remember to do means remembering a task before doing it. Stopped texting identifies what ended, while stopped to text explains the purpose of a pause. Regret missing the meeting expresses sorrow; regret to inform you introduces an unwelcome message.
Frequently Asked Questions
What is the difference between a gerund and an infinitive with verbs like “remember,” “stop,” and “regret”?
With these verbs, the choice between a gerund and an infinitive does more than change the structure of the sentence. It changes the meaning. A gerund is the -ing form acting like a noun, such as stopping, remembering, or regretting. An infinitive usually uses to plus the base verb, such as to stop, to remember, or to regret. The important point is that certain verbs take both forms, but each form points to a different idea about time, purpose, or attitude.
For example, remember doing something refers to a memory of a past action: “I remember locking the door.” This means the person locked the door and now has that memory. In contrast, remember to do something refers to not forgetting a future or necessary action: “Remember to lock the door.” Here, the action may not have happened yet, and the focus is on obligation or intention. The same pattern appears with stop and regret. Stop smoking means quit the activity. Stop to smoke means pause another activity in order to smoke. Regret saying it means feel sorry about something already said. We regret to inform you means you are sorry to give bad news now.
That is why this grammar point matters so much. The grammar form itself is small, but the meaning shift is not. In exams, professional writing, and ordinary conversation, choosing the wrong form can make your sentence unclear or even say the opposite of what you mean.
How does meaning change with “remember + gerund” versus “remember + infinitive”?
With remember + gerund, you are talking about a memory of something that already happened. The action came first, and the remembering happens after. For example, “She remembers meeting the client in Berlin” means the meeting took place in the past, and she still has that memory. This structure is connected to experience, recollection, and past events that remain in the mind.
With remember + infinitive, the meaning is very different. It means not forgetting to do something that is necessary, planned, or expected. For example, “She remembered to meet the client” means she did not forget the appointment. The focus is not on the memory of the event itself, but on whether she successfully kept the intention in mind before doing it.
A useful way to think about it is this: remember doing looks backward, while remember to do looks forward. Compare these two sentences: “I remember sending the email” and “I remembered to send the email.” The first means I have a memory of the act of sending it. The second means I did not forget the task. In real communication, this distinction is essential. If a manager says, “Did you remember to send the report?” they are asking whether the task was completed. If someone says, “I remember sending the report,” they are saying they have a clear memory that they completed it.
This distinction also explains why learners sometimes become confused. Both forms can appear with the same main verb and the same object, but the timeline changes. Once you focus on timing, the grammar becomes much easier to control.
What is the difference between “stop doing” and “stop to do”?
Stop doing means quit an activity or bring it to an end. For example, “He stopped talking” means he was talking, and then the talking ended. In this structure, the gerund names the activity that stops. It often appears when someone gives up a habit, interrupts an action, or ends behavior completely. “She stopped working at 6 p.m.” means her work ended at that time. “They stopped arguing” means the argument finished.
Stop to do, however, means pause one action in order to do another. For example, “He stopped to talk” means he was doing something else, then paused so that he could talk. The infinitive expresses purpose. It explains why the person stopped. In “She stopped to check her phone,” she did not end her day permanently; she paused another activity for the purpose of checking her phone.
In He stopped smoking when the alarm sounded, the activity ended at that moment. In He stopped smoking ten years ago, context suggests a lasting change of habit. He stopped to smoke gives the purpose of stopping something else. Do not add a permanent-cessation meaning unless the context supports it.
If you are unsure which form to use, ask yourself a simple question: did the person end the activity, or did they pause something else for a reason? If the activity itself ended, use the gerund. If the person paused in order to do something, use the infinitive.
How do “regret doing” and “regret to do” differ in tone and meaning?
Regret + -ing expresses sorrow about an action or situation. I regret saying that concerns earlier words. I regret not being able to attend tomorrow concerns a future event. The -ing form is not a universal past-time marker; the complete expression supplies the time reference.
Regret to do something is different. It is used when someone is sorry to perform an action now, especially when giving unpleasant information. For example, “We regret to inform you that your application was unsuccessful” is a standard formal expression. The speaker is about to deliver bad news and signals politeness and sympathy. The regret is connected to the act of informing, not to a past mistake.
The tone also changes. Regret doing often sounds emotional, direct, and personal. Regret to do often sounds formal, careful, and professional. That is why you frequently see the infinitive form in official emails, announcements, customer service messages, and business correspondence. It allows the speaker or writer to soften the impact of negative information.
To compare them clearly, consider these examples: “She regrets leaving the company” means she left in the past and now feels sorry about that decision. “She regrets to announce her resignation” means she is sorry to make the announcement now. One refers back to a completed action; the other refers to the present act of saying something unwelcome. Understanding that distinction helps you choose not only the correct grammar, but also the correct tone.
What are the best strategies for choosing between a gerund and an infinitive correctly in exams and real writing?
A useful strategy is to state the intended meaning, then check the complete pattern in a learner reference. Use separate examples for recollection, remembering a task, ending an activity, stopping for a purpose and announcing bad news. Avoid treating all -ing forms as past actions or all infinitives as future actions.
A second strong strategy is to learn high-frequency pairs as meaning contrasts, not as isolated grammar patterns. For example: remember doing = have a memory of a past action; remember to do = not forget a task. Stop doing = quit or end an activity; stop to do = pause in order to do something. Regret doing = feel sorry about a past action; regret to do = politely announce something negative. Studying them as pairs helps you notice how the meaning shifts each time.
A timeline can help with recollection and remembering a task, but it cannot replace the specific rule for each verb. For stop, identify the activity that ends and the purpose of the pause. For regret, distinguish an action or situation someone is sorry about from a formal announcement. These patterns do not apply to every verb in English.
Finally, pay attention to authentic examples in context. Business English often uses forms like “We regret to inform you,” while everyday conversation often includes forms like “I remember meeting him” or “She stopped talking.” The more examples you read and hear, the more natural the pattern becomes.
