What Are Gerunds?

A gerund is a word formed from a verb by adding -ing, but it functions as a noun in a sentence. For example, swim becomes swimming, read becomes reading, and cook becomes cooking. Although a gerund looks exactly like a present participle, the two serve very different purposes. A present participle is part of a verb tense or works as an adjective, while a gerund always acts as a noun — it can be a subject, an object, or the object of a preposition.

Gerunds are one of the most versatile and frequently used structures in the English language. They allow speakers to talk about activities, habits, and abstract ideas as though they were things. Instead of saying "I like it when I swim," a speaker can simply say "I like swimming." This makes English more natural, more concise, and more fluid. Mastering gerunds is essential for anyone who wants to speak and write English with confidence.

💡 Key Point

A gerund always ends in -ing and always functions as a noun. If the -ing word is acting as part of a verb tense or as an adjective, it is a present participle — not a gerund.

When Do We Use Gerunds?

Gerunds appear in many different positions within English sentences. They are used whenever you need the noun form of a verb. Here is a clear overview of the main situations where gerunds are required:

Function Description Example
As Subject The gerund is the subject of the sentence Swimming is great exercise.
As Object of a Verb The gerund follows certain verbs as the direct object She enjoys reading novels.
After Prepositions A verb after any preposition must be a gerund He is good at solving problems.
As Subject Complement The gerund follows "be" to define the subject Her favourite hobby is painting.
After Certain Expressions Fixed phrases that always require a gerund It's no use complaining about it.
📐 Formation

Base verb + -ing = Gerund

Examples: go → going, write → writing, run → running, study → studying, travel → travelling, dance → dancing

⚠️ Spelling Rules

Pay attention to spelling when forming gerunds:
✔ write → writing (drop the silent -e)
✔ run → running (double the final consonant after a short vowel)
✔ die → dying (change -ie to -y)
✔ play → playing (just add -ing after -y)

Gerunds as Subjects

One of the most common uses of gerunds is as the subject of a sentence. When a gerund is the subject, it always takes a singular verb. This structure is very natural in English and is used to talk about activities or ideas in general terms.

📐 Formula

Gerund (+ ...) + singular verb + ...

The gerund subject is always treated as third person singular, so the verb that follows must agree accordingly: "Swimming is" (not "Swimming are").

Gerund Subject Verb Full Sentence
Reading improves Reading improves your vocabulary.
Cooking is Cooking is a valuable life skill.
Jogging helps Jogging helps you stay fit and healthy.
Learning a language takes Learning a language takes time and patience.
Smoking causes Smoking causes serious health problems.
Travelling broadens Travelling broadens your horizons.
⚠️ Common Mistake

Do not use a plural verb with a gerund subject:
✘ Swimming are good for your health.
✔ Swimming is good for your health.

💡 Gerund vs. Infinitive as Subject

Both gerunds and infinitives can be used as subjects, but gerunds sound more natural and are far more common in everyday English:
Reading is fun. (natural, very common)
To read is fun. (grammatically correct but formal and rare)

Gerunds as Objects

Gerunds frequently appear as the direct object of a verb. Many common English verbs are followed by a gerund rather than an infinitive. This is one of the areas where learners make the most mistakes, so it is important to memorise which verbs take a gerund.

📐 Formula

Subject + verb + gerund (+ ...)

The gerund acts as the direct object of the main verb. You cannot use an infinitive after these verbs — only the -ing form is correct.

Subject Verb Gerund Object Full Sentence
I enjoy cooking I enjoy cooking Italian food.
She avoids eating She avoids eating fast food.
They finished painting They finished painting the house.
He suggested going He suggested going to the cinema.
We keep practising We keep practising every day.
I miss living I miss living in London.
⚠️ Common Mistake

Do not use an infinitive after verbs that require a gerund:
✘ I enjoy to swim in the sea.
✔ I enjoy swimming in the sea.
✘ She avoids to drink coffee at night.
✔ She avoids drinking coffee at night.

💡 Negative Gerunds

To make a gerund negative, simply place not before the gerund:
Not studying for the exam was a big mistake.
She regrets not telling him the truth.

Gerunds After Prepositions

Whenever a verb comes after a preposition in English, it must be in the gerund form. This is a fundamental rule with no exceptions. Prepositions include words like at, in, on, about, of, for, after, before, without, by, instead of, and many others.

📐 Formula

Preposition + gerund

After any preposition, always use the -ing form. Never use the base form or the infinitive after a preposition.

Expression Preposition Example
good at at She is good at speaking French.
interested in in He is interested in learning about history.
afraid of of They are afraid of flying.
instead of of She walked instead of taking the bus.
after after After finishing dinner, we went for a walk.
before before Wash your hands before eating.
without without He left without saying goodbye.
by by You can improve by reading every day.
tired of of I'm tired of waiting for the bus.
⚠️ Common Mistake

Do not use an infinitive or a base form after a preposition:
✘ She is good at to cook.
✔ She is good at cooking.
✘ I'm interested in learn English.
✔ I'm interested in learning English.

💡 The "To" Trap

Be careful with the word "to". When "to" is a preposition (not part of an infinitive), it must be followed by a gerund:
I look forward to meeting you. (preposition + gerund)
I'm used to waking up early. (preposition + gerund)
She objected to being treated unfairly. (preposition + gerund)
He is committed to improving his skills. (preposition + gerund)

Verbs Followed by Gerunds

There is a specific group of verbs in English that must be followed by a gerund, not an infinitive. These verbs need to be memorised because there is no simple rule to predict which verbs take gerunds. Here is a comprehensive list of the most important ones:

Verb Example
enjoy We enjoy exploring new cities.
avoid You should avoid making the same mistake twice.
mind Do you mind closing the window?
suggest She suggested taking a different route.
finish Have you finished writing the report?
keep He keeps forgetting his keys.
miss I miss playing football with my friends.
consider They are considering moving to Berlin.
practise She practises singing every morning.
deny He denied stealing the money.
admit She admitted making a serious mistake.
give up He gave up smoking last year.
postpone We postponed travelling until spring.
imagine Can you imagine living on Mars?
risk Don't risk driving in this weather.
can't help I can't help laughing at his jokes.
dislike She dislikes waking up early on weekends.
recommend I recommend visiting the museum in Paris.
💡 Memory Trick

Many verbs followed by gerunds relate to starting, stopping, continuing, or avoiding an action. Think of them as verbs that describe your relationship with an activity: you enjoy it, avoid it, keep doing it, give it up, finish it, or miss it.

A gerund transforms every action into an idea — it is the bridge between doing and being, the point where verbs become the very building blocks of thought.

Gerund Phrases

A gerund phrase is a gerund together with its objects, complements, or modifiers. The entire phrase functions as a single noun in the sentence. Gerund phrases allow you to express more detailed and complex ideas while keeping the sentence structure clean and readable.

📐 Formula

Gerund + object / complement / modifier = Gerund Phrase

The whole gerund phrase acts as one noun unit — it can be a subject, an object, or the object of a preposition, just like a simple gerund.

Gerund Phrase Function Full Sentence
Eating fresh fruit every day Subject Eating fresh fruit every day is good for your health.
reading before bed Object She enjoys reading before bed.
speaking in front of large audiences Object of preposition He is afraid of speaking in front of large audiences.
Walking along the river at sunset Subject Walking along the river at sunset is my favourite part of the day.
practising grammar exercises regularly Object We recommend practising grammar exercises regularly.
driving in heavy traffic Object Many people dislike driving in heavy traffic.
💡 Spotting Gerund Phrases

To identify a gerund phrase, find the -ing word and ask: "Does this -ing word have any objects or extra information attached to it?" If yes, the whole group of words together forms the gerund phrase. For example, in "Playing tennis on weekends keeps me active," the gerund phrase is "Playing tennis on weekends" — not just "Playing."

⚠️ Common Mistake

Do not confuse a gerund phrase with a continuous tense. In a gerund phrase, the -ing word is a noun:
Playing the guitar is his passion. (gerund phrase = subject)
✔ He is playing the guitar right now. (present continuous tense — not a gerund)

Common Expressions with Gerunds

English has many fixed expressions and phrases that always require a gerund. These expressions are extremely common in both spoken and written English. Learning them as complete chunks will make your English sound much more natural and fluent.

Expression Meaning Example
It's no use It is pointless / useless It's no use crying over spilt milk.
It's (not) worth It has (no) value / deserves effort This book is worth reading twice.
There's no point in It is useless / achieves nothing There's no point in arguing about it.

can't stand Hate / cannot tolerate I can't stand waiting in long queues.
feel like Want to / be in the mood for Do you feel like going for a walk?
be busy Be occupied with She was busy preparing for the exam.
look forward to Be excited about something future We look forward to hearing from you.
spend time Use time doing something He spends hours playing video games.
go + gerund Used for sports and activities We went hiking in the mountains last weekend.
⚠️ Common Mistake

Many learners use an infinitive after "look forward to" because they see the word "to" and think it introduces an infinitive. Remember: in this expression, "to" is a preposition:
✘ I look forward to meet you.
✔ I look forward to meeting you.

💡 Go + Gerund

The expression "go + gerund" is used for recreational activities and sports: go swimming, go shopping, go fishing, go skiing, go camping, go jogging, go hiking, go sightseeing, go cycling, go sailing. This structure is unique to English.

Gerunds vs. Present Participles

Since both gerunds and present participles end in -ing, students often confuse them. The key difference lies in their function within the sentence. A gerund acts as a noun, while a present participle acts as part of a verb tense or as an adjective. Understanding this distinction is essential for analysing English sentences correctly.

Feature Gerund Present Participle
Form verb + -ing verb + -ing
Function Acts as a noun Acts as a verb or adjective
As subject ✔ Swimming is fun. ✘ Not possible
As object ✔ I enjoy reading. ✘ Not possible
In continuous tenses ✘ Not a gerund ✔ She is reading now.
As adjective ✘ Not a gerund ✔ The running water is cold.
After prepositions ✔ Good at cooking. ✘ Not a participle
Can be replaced by a noun or "it" nothing (part of verb form)

Here are some side-by-side examples to illustrate the difference clearly:

Sentence -ing Word Is Why?
Swimming is my favourite sport. Gerund It is the subject of the sentence (= a noun)
She is swimming in the pool. Participle Part of present continuous tense (is + -ing)
I love painting. Gerund It is the object of "love" (= a noun)
The sleeping baby looks peaceful. Participle It describes the baby (= an adjective)
He is good at drawing. Gerund It follows a preposition (= a noun)
The boiling water is ready. Participle It describes the water (= an adjective)
💡 Quick Test

To determine if an -ing word is a gerund, try replacing it with a regular noun or the pronoun "it". If the sentence still makes sense, the -ing word is a gerund:
Swimming is fun.It is fun. ✔ (gerund confirmed)
She is swimming.She is it. ✘ (not a gerund — it is a present participle)

⚠️ Do Not Confuse

The form is identical — only the function differs. Always ask yourself: "Is this -ing word acting as a noun, or is it part of a verb tense / adjective?" The answer will tell you whether it is a gerund or a present participle.
