Fluent English doesn’t just mean speaking quickly—it means speaking naturally and correctly. One common area where English learners get stuck is choosing between gerunds and infinitives. Do you say “I enjoy to swim” or “I enjoy swimming”? What about “I want swimming” or “I want to swim”? Let’s break it down.

What are Gerunds and Infinitives?

Gerunds and infinitives are two forms of verbs that often function as nouns in a sentence. They are essential in English grammar, especially in spoken and written communication, and are used as subjects, objects, or complements in a sentence.

What is a Gerund?

• A gerund is the -ing form of a verb that functions as a noun.

Structure-

• Verb + ing → reading, writing, dancing, playing

Examples-

§  Swimming is good for health. (subject)

§  I enjoy reading novels. (object)

§  Her hobby is painting. (compliment)

• In conversation:

§  “I love jogging in the morning.”

§  (Here, jogging is a gerund acting as the object of “love.”)

 

What is an Infinitive?

• An infinitive is the base form of a verb usually preceded by "to". It also functions like a noun in many cases.

Structure-

• to + base verb → to read, to write, to dance, to play
• Examples-

§  I want to learn English. (object)

§  To travel the world is my dream. (subject)

§  Her goal is to become a doctor. (compliment)

• In conversation-

§  “He hopes to join the class tomorrow.”

§  (to join is the infinitive and the object of “hopes.”)

 

Form	Structure	Functions As	Example
Gerund	Verb + ing	Noun	“Running is fun.”
Infinitive	to + base verb	Noun/Adjective/Adverb	“She wants to run.”

 

 

When should you utilize Gerunds?

A gerund is the -ing form of a verb that functions as a noun in a sentence. You should use gerunds when the action (verb) becomes the subject or object of another action or statement. Here is a clear guide on when to use gerunds correctly:

• After certain verbs- A gerund, not an infinitive, always follows some verbs.

Common verbs that take gerunds-

§  Enjoy → I enjoy reading novels.

§  Avoid → He avoids talking too much.

§  Mind → Do you mind closing the window?

§  Suggest → She suggested taking a break.

§  Finish → They finished eating lunch.

§  Consider → I’m considering moving abroad.

§  Keep- Keep practising every day.

 

·       Conversation Tip- Use gerunds with these verbs to sound natural.

§  Right- “I enjoy swimming.”

§  Wrong- “I enjoy to swim.”

 

• As the subject of a sentence- When an action is the subject of a sentence, we use the gerund form.

Examples-

§  Smoking is harmful to health.

§  Dancing brings me joy.

§  Learning English takes time and effort.

• After prepositions- A gerund always follows a preposition, even when it comes after a verb or an adjective.
• Examples-

§  She’s interested in learning Spanish.

§  They left without saying goodbye.

§  I’m good at drawing.

§  He apologized for being late.

• Note: Never use the infinitive form after a preposition.

§  Wrong- “I’m good at to draw.”

§  Right- “I’m good at drawing.”

• After phrasal verbs- Many phrasal verbs (verb + preposition/adverb) are followed by gerunds.

Examples-

§  He gave up smoking.

§  She looks forward to meeting you.

§  They ended up cancelling the trip.

• In fixed expressions- Some expressions or phrases naturally take a gerund.

Examples-

§  It’s no use crying over spilled milk.

§  I can’t help laughing at that joke.

§  There’s no point in arguing.

• Bonus: Passive meaning with Gerunds- Sometimes gerunds imply a passive sense.

Example-

§  The room needs cleaning.

§  (= The room needs to be cleaned.)

When should you utilize Infinitives?

An infinitive is the base form of a verb usually preceded by "to" (e.g., to eat, to run, to learn). Infinitives often function as nouns, adjectives, or adverbs in sentences. Understanding when to use infinitives correctly is key to forming fluent, grammatically correct sentences especially in spoken English.

• After certain verbs- Many verbs are followed by infinitives (not gerunds).

Common verbs followed by infinitives-

§  Want → I want to eat.

§  Hope → She hopes to travel soon.

§  Plan → They plan to move abroad.

§  Decide → He decided to join the course.

§  Agree → We agreed to help them.

§  Learn → I’m learning to drive.

§  Promise → He promised to call me.

·       Conversation tip- Use infinitives to talk about intentions or future actions.

§  “I want to speak English fluently.”

• After certain adjectives- Use infinitives to explain reasons or results after adjectives.

For examples-

§  I’m happy to help.

§  She’s ready to go.

§  It isn’t easy to understand this topic.

§  He’s excited to meet you.

• To show purpose or intent- Infinitives often express why something is done.
• Examples-

§  I study to learn.

§  She works hard to succeed.

§  He came here to talk to you.

       You can often replace “in order to” with an infinitive-

§  “He trained to win the race.”

• As the subject or complement of a sentence- Infinitives can act as the subject or complement (predicate noun).

For instance-

§  To travel is my dream. (subject)

§  His goal is to become a pilot. (compliment)

§  To read every day helps improve vocabulary. (subject)

• After question words (what, how, where, etc.)- Use infinitives after question words to express decisions or uncertainty.

Examples-

§  I don’t know what to say.

§  Can you tell me how to get there?

§  She taught me how to swim.

• After certain nouns or pronouns- Infinitives can follow certain nouns or pronouns to express what someone needs or wants to do.

For examples:

§  I have a book to read.

§  There’s nothing to do.

§  She’s the one to ask.

Such as: Stop

How do you practice in real-life situations?

1. Listen to native speakers (podcasts, shows) and note verb patterns.
