What is a Gerund Noun?
Definition, Rules, Examples & Gerund Phrase Lists
A gerund is a verb form ending in -ing that functions syntactically as a noun, allowing an activity or state to serve as a subject, direct object, or object of a preposition (e.g., reading, running, cooking).
Gerunds look like present participles but behave like nouns, giving sentences variety and momentum when expressing habits, passions, and complex actions. Learn how to tell gerunds apart from continuous verbs, pair them with possessive pronouns, and use them naturally in composition.

• Understanding Gerunds
A gerund is a neat grammatical trick that turns an action into a concept. By taking a verb and adding "-ing" to the end, the word transforms into a noun. This allows you to talk about "swimming" or "reading" as an activity or a hobby, rather than an action someone is currently doing.
Here is how gerunds separate themselves from standard nouns and verbs:
Verb + -ing = Noun
A gerund is structurally identical to a present participle, but its grammatical role is strictly that of a noun representing an activity.
Conceptual Actions
While standard nouns name physical objects or abstract ideas, gerunds name actions as concepts or habits.
Gerund Phrases
Because they come from verbs, gerunds can still take direct objects and adverbs, forming a single noun phrase.
• See it in Context
Using gerunds gives sentences variety and flow. Instead of relying heavily on standard nouns, slipping a gerund into the subject or object position allows you to quickly summarize complex actions and habits in a single, digestible word.
• Key Rules & Usage
Although they always look identical in structure (ending in -ing), gerunds take on different syntactical roles depending on where they sit in a sentence, such as acting as the main subject or the object of a preposition.
The -ing Suffix Rule
A gerund will always, without exception, end in -ing. If it does not end in -ing, it is not a gerund.
- Dance becomes dancing .
- Write becomes writing .
The "It" Replacement Test
Since a gerund functions as a noun, you can usually replace it with the pronoun "it" and the sentence will still make grammatical sense.
- I enjoy reading -> I enjoy it.
- Running is hard -> It is hard.
Negative Gerunds
To make a gerund negative, simply place the word "not" directly before the gerund.
- The doctor suggested not eating red meat.
- Not sleeping will make you tired.
Gerund Phrases
Because gerunds retain verb-like qualities, they can take direct objects and adverbs.
- Running in the rain is my favorite.
- He avoided answering the tough questions .
• Gerund Roles in a Sentence
Because a gerund is a noun, it can occupy almost any slot in a sentence that a normal noun can. Depending on where you place it, a gerund takes on a specific grammatical job.
Subject
The gerund acts as the main topic or "doer" of the sentence.
Direct Object
The gerund receives the action of the main verb in the sentence.
Object of a Preposition
A gerund that immediately follows a preposition (like in, on, at, of, about).
Subject Complement
The gerund follows a linking verb (like "is") and renames or describes the subject.
• Gerunds vs. Participles & Infinitives
Gerunds often get mixed up with two other verbals: Present Participles (which also end in -ing) and Infinitives (which also act as nouns). Knowing the difference will save you from common structural pitfalls.
Gerund vs. Present Participle
Both end in -ing. However, participles act as adjectives or form continuous verbs (e.g., "The barking dog"). Gerunds act strictly as nouns.
Gerund vs. Infinitive
Both can act as nouns. Some verbs (like "enjoy") only take gerunds. Some (like "want") only take infinitives ("to go"). Some can take both with different meanings.
The Possessive Rule
In formal writing, you should use a possessive noun or pronoun before a gerund (e.g., "my going" rather than "me going") because the gerund is a noun.
• Top 50 Common Gerunds
Any verb can become a gerund by adding -ing. However, some actions are discussed as concepts much more frequently than others in daily life. Here are 50 of the most commonly used gerunds in the English language.
