Understanding the nuances of English grammar can significantly enhance your writing clarity and impact. Among the more challenging but essential elements are gerunds and infinitives, verb forms that function as nouns, adjectives, or adverbs. Mastering these structures is key to constructing sophisticated and grammatically correct sentences.
This guide aims to demystify gerunds and infinitives, providing clear explanations and practical examples. We will explore their formation, common uses, and the often-confusing situations where one is preferred over the other. Through targeted practice, you will gain the confidence to use these versatile verb forms accurately and effectively in your own writing.
Understanding Gerunds
A gerund is the -ing form of a verb used as a noun. It can function as a subject, object, or complement in a sentence. Recognizing gerunds is the first step to understanding their role.
For instance, in the sentence “Swimming is my favorite exercise,” the word “swimming” is a gerund acting as the subject of the verb “is.” It represents the activity itself, functioning precisely like a noun.
Gerunds can also appear as direct objects. Consider the sentence, “She enjoys reading novels.” Here, “reading” is the gerund, receiving the action of the verb “enjoys.” The object of her enjoyment is the act of reading.
Furthermore, gerunds can serve as the object of a preposition. An example is, “He is interested in learning a new language.” The preposition “in” is followed by the gerund “learning,” which is the object of the preposition.
The subject complement role for gerunds is also common. In the sentence, “Her passion is painting,” the gerund “painting” renames or describes the subject “passion,” functioning as a subject complement.
When a sentence begins with a verb form and that form acts as the subject, it is almost always a gerund. This is a straightforward indicator to identify the gerund’s function. Pay attention to the initial position of the -ing word.
Possessive pronouns or nouns often precede gerunds when the gerund is the subject or object. For example, “His singing was off-key” or “I appreciate your helping me.” The possessive indicates ownership of the action or the action itself.
Gerunds are essential for naming activities or concepts. They provide a concise way to refer to ongoing actions or states as concrete entities. This noun-like quality makes them indispensable for expressing ideas.
Avoid confusing gerunds with present participles, which also end in -ing but function as adjectives or parts of continuous verb tenses. The key difference lies in their grammatical role within the sentence.
The grammatical function of a gerund as a noun is its defining characteristic. Whether it’s the subject, object, or complement, it behaves like a noun in every respect. This consistency simplifies their identification once their role is understood.
Common Verbs Followed by Gerunds
Certain verbs are consistently followed by gerunds. Memorizing these common verbs will greatly assist in accurate sentence construction. These verbs often express states of being, preferences, or actions that imply completion or enjoyment.
Verbs like “enjoy,” “finish,” “avoid,” “mind,” and “quit” typically take gerunds as their objects. For example, “They finished painting the room” or “Please avoid making noise.” These verbs signify the completion or deliberate abstinence from an action.
Phrasal verbs also commonly use gerunds. Examples include “give up,” “put off,” “look forward to,” and “go on.” After “look forward to,” for instance, you would say “I look forward to meeting you,” not “meeting.” The preposition “to” is part of the phrasal verb, not the infinitive marker.
Verbs expressing likes and dislikes, such as “love,” “like,” “hate,” and “dislike,” can be followed by either gerunds or infinitives, though sometimes with a slight difference in meaning. “I love swimming” emphasizes the enjoyment of the activity itself. “I like to swim” can imply a preference for swimming over other activities or a habitual action.
Verbs of beginning and ending, like “start,” “begin,” “stop,” and “cease,” also commonly precede gerunds. “The rain started falling heavily” uses “falling” as a gerund. This indicates the initiation of the action.
Consider the verb “suggest.” It is almost always followed by a gerund. “She suggested visiting the museum” is correct, whereas “She suggested to visit the museum” is not standard English. The focus is on the recommendation of the activity.
The verb “admit” also requires a gerund. “He admitted stealing the money” is the correct construction. The gerund “stealing” acts as the direct object of “admitted.”
Similarly, verbs like “deny,” “imagine,” and “regret” are typically followed by gerunds. “They denied knowing anything about it” or “I imagine working from home would be great.” These verbs describe actions or states that are being denied, imagined, or regretted.
Mastering this list of verbs and their tendency to take gerunds is a crucial step. Consistent practice and exposure to examples will solidify your understanding and application.
Understanding Infinitives
An infinitive is the base form of a verb, usually preceded by “to.” It can function as a noun, adjective, or adverb. Infinitives offer a different way to express purpose, intention, or action.
The most common form is the “to-infinitive,” like “to run,” “to eat,” or “to think.” This structure is highly versatile in its grammatical roles.
As a noun, an infinitive can be a subject. “To err is human” uses “to err” as the subject of the sentence. It represents the act of making mistakes.
Infinitives also function as direct objects. “He wants to learn guitar.” Here, “to learn” is the direct object of the verb “wants.” It specifies what he wants.
They can also serve as subject complements. “My goal is to finish the marathon.” The infinitive “to finish” renames or explains the subject “goal.”
Infinitives frequently act as adverbs, explaining the reason or purpose for an action. “She studied hard to pass the exam.” The infinitive “to pass” tells us why she studied hard.
As adjectives, infinitives modify nouns or pronouns. “I have a lot of work to do.” The infinitive “to do” describes the noun “work,” specifying the nature of the work.
There is also the bare infinitive, which is the base form of the verb without “to.” It is used after certain verbs like “make,” “let,” “help,” and modal verbs (can, could, will, would, etc.). For example, “Let me go” or “You should study.”
Understanding the core function of the infinitive as a verb form that can take on noun, adjective, or adverbial roles is fundamental. Its structure provides a flexible way to embed actions or intentions within sentences.
Common Verbs Followed by Infinitives
Many verbs are followed by infinitives, particularly when expressing desires, intentions, decisions, or plans. Learning these common verbs will greatly improve your accuracy.
Verbs like “want,” “hope,” “wish,” “decide,” “plan,” and “agree” are typically followed by infinitives. For example, “They decided to leave early” or “She hopes to travel the world.” These verbs indicate a future intention or a choice made.
Verbs expressing willingness or refusal, such as “agree,” “refuse,” and “offer,” also take infinitives. “He offered to help with the move” is a correct construction. The infinitive “to help” is the object of “offered.”
Verbs of learning and remembering, like “learn,” “forget,” and “remember,” are often followed by infinitives when referring to a future action or a task to be done. “I need to remember to buy milk.” Here, “to buy” is the infinitive object of “remember.”
The verb “seem” and its variations often take infinitives. “It seems to be raining outside.” The infinitive “to be raining” describes the appearance or impression.
Consider the verb “promise.” It is almost always followed by an infinitive. “He promised to call me later.” The infinitive “to call” specifies the action promised.
Verbs like “manage,” “fail,” and “pretend” also commonly take infinitives. “She managed to fix the computer” or “He pretends to be sick.” The infinitive explains how they managed or what they are pretending.
The verb “need” followed by an infinitive expresses necessity or obligation. “We need to finish this report by Friday.” The infinitive “to finish” clarifies the requirement.
Learning these patterns will help you predict whether a gerund or an infinitive is appropriate after a particular verb. Practice is key to internalizing these common collocations.
Gerunds vs. Infinitives: When to Use Which
The choice between a gerund and an infinitive can be tricky, as some verbs can be followed by either, sometimes with a subtle change in meaning. Understanding the general rules and exceptions is crucial.
As a rule of thumb, verbs expressing likes, dislikes, or preferences (love, like, hate, prefer) can often take either form. “I like swimming” might emphasize the enjoyment of the activity, while “I like to swim” could refer to a habit or a specific instance.
Verbs of beginning and ending (start, begin, stop, continue) also often accept both. “The music started playing” and “The music started to play” are both grammatically correct, with minimal semantic difference in most contexts.
However, some verbs *only* take gerunds, and others *only* take infinitives. This is where memorization and practice become essential. For example, “avoid” takes a gerund (“He avoided talking to her”), while “decide” takes an infinitive (“She decided to go home”).
The context of the sentence often dictates the choice. If you are referring to an activity as a concept or a subject, a gerund is usually appropriate. If you are referring to a purpose, intention, or a specific future action, an infinitive is often the better choice.
Consider the difference between “I stopped smoking” and “I stopped to smoke.” The first means you quit the habit of smoking. The second means you paused your current activity in order to smoke.
The verb “remember” and “forget” can take either, but the meaning changes significantly. “I remember telling him” means you recall the past event. “I remember to tell him” means you recall the obligation to tell him in the future.
Similarly, “regret” behaves differently. “I regret saying that” expresses remorse for a past action. “I regret to inform you” is a formal way of introducing bad news, indicating a present, unpleasant task.
Certain prepositions are always followed by gerunds. For instance, after prepositions like “about,” “after,” “before,” “by,” “for,” “in,” “on,” and “without,” you will use a gerund. “She is good at drawing” or “He left without saying goodbye.”
The infinitive is often used to express purpose. Phrases like “in order to” or “so as to” are followed by infinitives. “He worked hard in order to succeed.” This clearly states the purpose of his hard work.
When a verb is followed by an adjective, an infinitive is often used. “It’s important to be punctual.” The infinitive “to be” complements the adjective “important.”
The bare infinitive, without “to,” is used after verbs of perception (see, hear, feel, watch, notice) when referring to the entire action. “I saw him leave.” However, if you are referring to an ongoing action, you would use the present participle: “I saw him leaving.”
Verbs like “help” can be followed by either a bare infinitive or a to-infinitive. “She helped me move the furniture” and “She helped me to move the furniture” are both acceptable. The bare infinitive is often more common in American English.
Understanding these distinctions requires careful attention to the specific verb and the intended meaning. Context is your most valuable guide in these nuanced situations.
Practice Exercises
Applying the rules of gerunds and infinitives through practice is essential for mastery. These exercises will help reinforce your understanding and identify areas needing further attention.

1. She is considering (apply) for the scholarship. (Verb: consider)
2. He promised (call) me as soon as he arrived. (Verb: promise)
3. We decided (go) to the park. (Verb: decide)
4. I enjoy (listen) to music. (Verb: enjoy)
5. They finished (clean) the house. (Verb: finish)
6. It’s important (study) for the test. (Adjective: important)
7. He avoids (eat) junk food. (Verb: avoid)
8. My dream is (travel) the world. (Verb: dream)
9. She needs (finish) her assignment. (Verb: need)
10. They hope (win) the championship. (Verb: hope)
11. I regret (not study) harder in college. (Verb: regret)
12. He pretended (be) asleep. (Verb: pretend)
13. I saw the cat (jump) over the fence. (Verb of perception: saw)
14. Let me (help) you with that. (Verb: let)
15. We are looking forward to (see) you soon. (Phrasal verb: look forward to)
The answers are: 1. applying, 2. to call, 3. to go, 4. listening, 5. cleaning, 6. to study, 7. eating, 8. to travel, 9. to finish, 10. to win, 11. not studying, 12. to be, 13. jump (or jumping), 14. help, 15. seeing.
Pay close attention to the verbs that exclusively take one form or the other. For verbs like “see,” consider whether the entire action or an ongoing part of it is being perceived.
Advanced Practice: Identifying Nuances
This section focuses on sentences where the choice between a gerund and an infinitive significantly alters the meaning. Analyze the subtle differences and choose the correct form.
1. I stopped (smoke) two years ago. (Meaning: I quit the habit.)
2. I stopped (buy) cigarettes. (Meaning: I ceased the action of purchasing them.)
3. He remembered (lock) the door. (Meaning: He recalled the past action of locking.)
4. He remembered (to lock) the door. (Meaning: He recalled his obligation to lock it.)
5. I tried (learn) Spanish. (Meaning: I made an attempt to learn.)
6. I tried (open) the jar with the lid. (Meaning: I experimented with this method.)
7. She went on (talk) about her vacation. (Meaning: She continued the act of talking.)
8. She went on (to talk) about her vacation after finishing her main speech. (Meaning: She proceeded to the next topic.)
9. He forgot (meet) her at the station. (Meaning: He failed to recall the appointment.)
10. He forgot (to meet) her at the station. (Meaning: He failed to fulfill the obligation to meet her.)
The answers are: 1. smoking, 2. buying, 3. locking, 4. to lock, 5. to learn, 6. opening, 7. talking, 8. to talk, 9. meeting, 10. to meet.
These examples highlight how critical the verb choice and the subtle shift in meaning can be. Recognizing these differences is a sign of advanced grammatical proficiency.
Common Pitfalls and How to Avoid Them
Several common errors arise when using gerunds and infinitives. Being aware of these pitfalls can help you avoid them in your own writing.
One frequent mistake is using an infinitive after a preposition. Remember that prepositions are almost always followed by gerunds. “He is interested in to learn” is incorrect; it should be “He is interested in learning.”
Another common error involves confusing the subject and object roles. Ensure that the -ing form is functioning as a noun when it’s a gerund, not as part of a continuous verb tense or an adjective.
The use of the bare infinitive can also be confusing. It is specifically used after certain verbs like “let,” “make,” and “help,” and after modal verbs. Do not use “to” after these specific constructions.
Misinterpreting the meaning change with verbs like “remember,” “forget,” and “stop” is another pitfall. Always consider whether you are referring to a past action, a future obligation, or the cessation of an activity.
Failing to recognize phrasal verbs that end in prepositions can lead to errors. For example, “look forward to” requires a gerund because “to” here is part of the phrasal verb, not an infinitive marker. “I look forward to hearing from you.”
When using verbs that can take either a gerund or an infinitive, be mindful of the subtle differences in meaning. Choose the form that best conveys your intended message.
Incorrectly using a gerund when an infinitive is required after specific verbs is a common oversight. For example, “She decided going” should be “She decided to go.”
Conversely, using an infinitive after verbs that exclusively take gerunds, such as “suggest” or “deny,” is also an error. “He suggested to leave” should be “He suggested leaving.”
Pay attention to the structure of sentences involving verbs of perception. While “I saw him leave” is correct (bare infinitive), “I saw him leaving” is also correct, indicating an ongoing action.
Mastering gerunds and infinitives involves consistent practice and a keen awareness of grammatical rules and common exceptions. By focusing on these areas, you can significantly improve your command of English grammar.
