Gerunds and infinitives cause more learner errors than almost any other grammar point because both forms can act like nouns, both often follow verbs, and both are shaped by patterns that are only partly logical. In practical terms, a gerund is the -ing form of a verb used as a noun, as in “Swimming is good exercise,” while an infinitive is the base form usually preceded by “to,” as in “To swim every day takes discipline.” If you are studying English grammar, teaching it, or editing professional writing, mastering gerunds vs infinitives matters because the choice changes correctness, meaning, tone, and sometimes even formality.
I have taught this topic in mixed-level classes and reviewed thousands of learner sentences, and the same problems appear repeatedly: students say “I enjoy to read,” “She suggested to go,” or “He made me to laugh.” These mistakes happen because English uses several overlapping patterns. Some verbs take only gerunds, some take only infinitives, some allow both with no real change in meaning, and some allow both but change meaning completely. This article serves as a hub for the miscellaneous side of the grammar topic by giving you a clear framework, a quick quiz, and the most common errors with direct fixes. If you understand the patterns here, every related grammar lesson becomes easier.
A useful way to think about the difference is function. Gerunds behave more like activities viewed as concepts or experiences: “I enjoy reading.” Infinitives often point to purpose, intention, decision, or possibility: “I want to read.” That rule is not enough on its own, but it helps. English also has fixed combinations after adjectives, nouns, and expressions such as “afraid to ask,” “a chance to improve,” and “it is worth checking.” Because these structures appear in exams, emails, reports, and conversation, accuracy here improves fluency fast. The sections below answer the questions learners usually ask and connect this page to the broader grammar hub through patterns you will see again in articles on verb forms, sentence structure, and common usage mistakes.
What Gerunds and Infinitives Do in a Sentence
Both gerunds and infinitives can be subjects, objects, and complements, but they do not appear in the same places with the same verbs. A gerund works like a noun built from a verb: “Running helps me think.” It can follow a verb: “She avoided answering.” It can also follow a preposition: “He left without saying goodbye.” That last pattern is essential. After a preposition, English normally uses a gerund, not an infinitive. So we say “interested in learning,” “good at solving,” and “before leaving.”
An infinitive often follows verbs of desire, decision, and plan: “hope to win,” “decide to wait,” “plan to expand.” It also commonly expresses purpose: “She called to confirm the booking.” In professional writing, infinitives frequently follow adjectives and abstract nouns: “ready to launch,” “important to note,” “an opportunity to grow.” One reason this topic feels difficult is that learners try to apply one rule everywhere. In reality, the controlling word determines the pattern. The question is usually not “Which form sounds better?” but “What does this verb, adjective, or expression require?”
Quick Quiz: Test Your Choice
Use this quick gerunds vs infinitives practice set before reading the error list. Choose the correct form in each sentence. Answers follow immediately so the section works like a self-check resource. One: “I can’t afford ___ a mistake in this report.” Two: “She admitted ___ the file late.” Three: “We discussed ___ the launch date.” Four: “He refused ___ the contract.” Five: “They are interested in ___ abroad.” The correct answers are: one, “to make”; two, “submitting”; three, “changing”; four, “to sign”; five, “working.”
Why are those answers correct? “Afford” and “refuse” are standard infinitive verbs. “Admit” takes a gerund because it refers to acknowledging a past action. “Discuss” is followed by a gerund-like noun phrase when the next word functions as the activity itself: “discussed changing,” not “discussed to change.” “Interested in” ends with the preposition “in,” so the next verb must be a gerund. If you missed two or more, do not memorize isolated sentences. Learn the governing pattern behind each one.
| Pattern | Common Verbs or Expressions | Example |
|---|---|---|
| Verb + gerund | enjoy, avoid, suggest, admit, consider | She suggested waiting. |
| Verb + infinitive | want, decide, hope, refuse, need | They decided to leave. |
| Verb + gerund or infinitive, same meaning | begin, start, continue, like, love | He started to speak / speaking. |
| Verb + gerund or infinitive, different meaning | stop, remember, forget, try, regret | I stopped smoking / stopped to smoke. |
| Preposition + gerund | in, on, at, after, before, without | After finishing, call me. |
Verbs Commonly Followed by Gerunds
The safest high-frequency gerund verbs to memorize first are enjoy, avoid, consider, suggest, admit, deny, finish, mind, risk, and recommend. These verbs regularly take the -ing form. In classrooms, I see “suggest to go” more than almost any other mistake. Standard English uses “suggest going” or “suggest that we go.” Similarly, “I enjoy to cook” should be “I enjoy cooking,” and “She avoided to answer” should be “She avoided answering.” When learners lock in these common verbs early, their error rate drops noticeably.
There is also an important meaning pattern here. Many gerund verbs refer to experiences already happening, general activities, or actions viewed as facts. “Admit stealing” points backward to an action. “Consider moving” treats moving as an option under discussion. “Risk losing” frames losing as a possible consequence of another action. This does not mean all gerund verbs are about the past, but it explains why they often feel more concrete and event-based than infinitive verbs.
Verbs Commonly Followed by Infinitives
Many core infinitive verbs express intention, willingness, choice, or future orientation. The most useful group includes want, need, plan, decide, hope, expect, refuse, promise, agree, and learn. These are everywhere in business English and everyday conversation: “We plan to hire,” “I hope to improve,” “She agreed to help.” A good editing habit is to check the first verb. If it expresses a plan, decision, or desire, an infinitive is often the correct next form.
Be careful with verbs that can take an object before the infinitive. “I want to leave” is correct, but so is “I want him to leave.” “She advised me to wait” is standard, while “She suggested me to wait” is not. That contrast matters because learners often overgeneralize from one structure to another. Usage dictionaries and corpus tools such as the Cambridge Dictionary, Merriam-Webster, and the Corpus of Contemporary American English confirm these patterns consistently.
When Both Forms Are Possible
Some verbs allow both forms. With begin, start, continue, like, and love, the meaning often stays nearly the same: “It started raining” and “It started to rain” are both natural. In careful style work, there can be minor differences in rhythm or emphasis, but for most learners, either form is acceptable. This is useful because it shows English is not always a rigid either-or system.
Other verbs change meaning depending on the form, and these deserve close attention. “Stop smoking” means quit the habit. “Stop to smoke” means pause another activity in order to smoke. “Remember locking the door” refers to a memory of a completed action. “Remember to lock the door” means do not forget a future duty. “Try restarting the router” means test a method. “Try to restart the router” means attempt the action, perhaps with difficulty. These are not small differences; they change the message entirely.
Common Errors and How to Fix Them
The first common error is using an infinitive after a preposition. Write “for improving,” not “for to improve.” Write “without missing,” not “without to miss.” The second is forcing an infinitive after a gerund verb: “recommend checking,” not “recommend to check.” The third is forgetting bare infinitives after certain verbs. We say “make someone do,” “let him go,” and often “help her finish,” although “help her to finish” is also accepted. The fourth is mixing patterns with object pronouns: “I expect him to come,” but “I suggest that he come” or “I suggest coming early.”
Another frequent issue is using a gerund where an infinitive of purpose is needed. “I went to the store to buy milk” is correct. “I went to the store buying milk” changes the structure and sounds wrong unless “buying milk” modifies a noun in a different sentence. Finally, many learners memorize lists but ignore collocation. Real fluency comes from learning chunks such as “decide to,” “avoid -ing,” “interested in -ing,” and “remember to.” Review your own writing, highlight every verb pair, and check whether the controlling word licenses a gerund, an infinitive, or both. That small habit builds accuracy quickly and makes the rest of grammar study more productive.
Gerunds vs infinitives practice works best when you move beyond memorizing random examples and start noticing patterns in authentic English. Learn the high-frequency gerund verbs, the common infinitive verbs, the preposition rule, and the small set of verbs that change meaning with each form. Those four areas account for most real errors. They also support other grammar skills, including verb complementation, sentence clarity, and natural phrasing in speech and writing.
As the hub page for this miscellaneous grammar subtopic, this article gives you the framework you need before exploring linked lessons on verb patterns, prepositions, reporting structures, and usage corrections. If you want faster improvement, take the quiz again, write five original sentences for each main pattern, and edit one recent email or paragraph for gerund and infinitive choices. Consistent short practice is what turns recognition into automatic accuracy.
Frequently Asked Questions
What is the difference between a gerund and an infinitive?
A gerund is the -ing form of a verb used as a noun, while an infinitive is the base form of a verb, usually with to, also used in noun-like positions. For example, in “Swimming is good exercise,” swimming functions as the subject of the sentence, so it is a gerund. In “To swim every day takes discipline,” to swim functions as the subject, so it is an infinitive. Both forms can behave like nouns, which is exactly why learners often confuse them. The challenge is that English does not always let you choose freely between the two. Some verbs are followed naturally by a gerund, some by an infinitive, and some can take both with either the same meaning or a different meaning. Understanding the basic form is easy; mastering the patterns is what takes practice.
Why do learners make so many mistakes with gerunds and infinitives?
Learners struggle with gerunds and infinitives because this grammar point combines form, meaning, and memorization. First, both structures can appear in similar positions, especially after verbs, which makes them look interchangeable. You can say “I enjoy reading” but “I want to read,” and there is no simple rule that explains every choice. Second, some verbs change meaning depending on whether they are followed by a gerund or an infinitive. For instance, “I stopped smoking” means quitting the habit, while “I stopped to smoke” means pausing another activity in order to smoke. Third, learners often transfer patterns from their first language, and those patterns do not always match English usage. Finally, many textbooks present long lists of verbs without enough context, so students memorize rules mechanically but still hesitate in real communication. The best way to reduce errors is to combine pattern recognition, repeated exposure, and short, focused practice such as quizzes and error correction exercises.
How can I tell whether a verb should be followed by a gerund or an infinitive?
The most reliable method is to learn common verb patterns and study them in meaningful examples. Some verbs are commonly followed by gerunds, such as enjoy, avoid, consider, suggest, and finish. For example: “She enjoys reading,” “They avoided talking about it,” and “We finished writing the report.” Other verbs usually take infinitives, such as want, hope, decide, plan, and need. For example: “He wants to leave,” “They decided to wait,” and “I need to study.” There is also a middle group of verbs like begin, start, like, love, and hate that can often take either form, though style or nuance may differ slightly depending on the sentence. In practice, it helps to learn verbs in chunks rather than in isolation. Instead of memorizing enjoy by itself, memorize enjoy doing something. Instead of memorizing decide alone, memorize decide to do something. This pattern-based approach is much more effective than trying to invent a rule every time you speak or write.
What are the most common gerund vs. infinitive errors in quizzes and real writing?
One very common error is using an infinitive after a verb that requires a gerund, such as “I enjoy to read” instead of “I enjoy reading.” The opposite error is also frequent: using a gerund after a verb that normally takes an infinitive, such as “She decided going” instead of “She decided to go.” Another major problem involves verbs that allow both forms but with different meanings. As mentioned earlier, stop, remember, forget, regret, and try are especially important. For example, “I remembered locking the door” means I have a memory of that past action, while “I remembered to lock the door” means I did not forget to do it. Learners also make mistakes after prepositions, because prepositions are followed by gerunds, not infinitives. So “She is interested in learn English” is incorrect; it should be “She is interested in learning English.” In professional editing and academic writing, these errors stand out because they affect both grammar and meaning. That is why quick quizzes are useful: they reveal whether the learner truly understands the pattern or is only guessing based on what sounds familiar.
What is the best way to practice gerunds and infinitives quickly and effectively?
The fastest effective method is to combine short quizzes, targeted review, and sentence-level production. Start with a quick quiz that focuses on high-frequency verbs and asks you to choose between a gerund and an infinitive. This helps identify your weak areas immediately. Next, review your mistakes by grouping them into categories: verbs followed by gerunds, verbs followed by infinitives, verbs that take both, and verbs that change meaning depending on the form used. After that, write your own example sentences. If you missed enjoy, decide, stop, and remember, create two or three original sentences for each one. Speaking practice also helps because it trains you to retrieve the pattern automatically, not just recognize it on paper. For teachers and editors, error analysis is especially powerful: take incorrect sentences such as “He suggested to leave” or “I hope seeing you soon” and correct them while explaining why. The goal is not only to know the rule but to build instinct. With repeated, focused practice, learners begin to notice these structures naturally in reading and listening, and that is when real improvement happens.
