Gerunds and Infinitives: Why "Enjoy to Swim" Sounds Wrong

"I enjoy to swim" is easy to understand, but it makes English do a tiny faceplant. The idea is clear. The problem is the shape after enjoy. English does not say enjoy to do. It says enjoy doing: "I enjoy swimming."

Gerunds and infinitives are not about deep philosophy. They are about which verb shape naturally follows another word. Some verbs want -ing. Some verbs want to + base verb. Some can take both, sometimes with a change in meaning. That is the whole game.

Quick Answer

A gerund is the -ing form used like a noun:

• Swimming is relaxing.
• I enjoy reading.
• She is good at explaining problems.

An infinitive is to + base verb:

• I want to leave.
• He forgot to call.
• We decided to wait.

Many common verbs are followed by one pattern more naturally than the other. Learn them in small groups, not as one giant list. The most useful rule is this: check the first verb. It usually decides the shape of the next verb.

The Pattern

Verbs Often Followed by Gerunds

Use verb + -ing after verbs like:

• enjoy
• avoid
• finish
• keep
• mind
• suggest
• consider
• practice

Examples:

• I enjoy cooking on weekends.
• She avoided answering the question.
• We finished cleaning the kitchen.
• He keeps forgetting his password.
• Would you mind opening the window?
• They suggested meeting earlier.

These verbs treat the second action like an activity, habit, or experience.

Verbs Often Followed by Infinitives

Use verb + to + base verb after verbs like:

• want
• need
• hope
• decide
• plan
• promise
• agree
• learn

Examples:

• I want to rest.
• We need to leave soon.
• She hopes to study abroad.
• They decided to cancel the meeting.
• He promised to help.
• I am learning to drive.

These verbs often point toward a goal, intention, plan, or future action.

Verbs That Can Take Both

Some verbs can use both patterns:

• I like swimming.
• I like to swim before work.
• We started eating.
• We started to eat.

Sometimes the meaning is almost the same. Sometimes it changes:

• I stopped smoking. I quit the activity.
• I stopped to smoke. I stopped another activity in order to smoke.
• She remembered locking the door. She has a memory of doing it.
• She remembered to lock the door. She did not forget the task.

When meaning changes, the pattern matters a lot.

Natural Examples

Everyday Plans

• I need to buy groceries.
• We decided to try the new restaurant.
• He hopes to finish early.

These look forward. The action is a goal, plan, or intention, so the infinitive feels natural.

Hobbies and Habits

• I enjoy baking bread.
• She practices speaking every day.
• They keep arriving five minutes late.

These describe activities or repeated behavior, so gerunds are common.

Polite Requests

• Would you mind closing the door?
• Could you help me carry this box?
• I would like to ask a question.

Notice that different request phrases use different patterns. Mind takes a gerund. Would like takes an infinitive. Help can often be followed by a base verb or an infinitive: "help me carry" or "help me to carry."

After Prepositions

After a preposition, use a gerund:

• She is interested in learning design.
• He apologized for arriving late.
• They talked about moving to a bigger office.
• I am tired of waiting.

This pattern is extremely useful because prepositions appear everywhere. If you see in, for, about, of, after, before, or without, the next verb usually becomes -ing.

After Adjectives

Many adjective patterns use infinitives:

• I am happy to help.
• She was surprised to hear the news.
• The instructions are easy to follow.
• This problem is hard to explain.

These adjectives often describe a reaction, judgment, or difficulty connected to an action. The infinitive points to the action that explains the adjective.

But adjectives followed by prepositions still follow the preposition rule:

• I am excited about starting the course.
• He is responsible for checking the forms.
• They are tired of waiting.

So do not only look at the adjective. Look at the word immediately before the second verb. If that word is a preposition, -ing is usually waiting nearby.

The First-Verb Habit

The fastest way to improve is to learn the first verb together with its favorite pattern. Do not memorize enjoy alone. Memorize enjoy doing. Do not memorize decide alone. Memorize decide to do. The pattern should travel with the verb like a backpack.

Try making tiny personal examples:

• I enjoy watching quiet videos before bed.
• I decided to clean my desk.
• I avoided checking my phone.
• I hope to finish early.

Short examples are powerful because they become reusable sentence pieces. Later, when you need a longer sentence, your brain already has the shape ready.

One more useful habit: practice the pattern in both positive and negative sentences. "I enjoy cooking" should travel with "I do not enjoy cooking." "I decided to go" should travel with "I decided not to go." The negative form often reveals whether the pattern is automatic or only memorized in one fixed sentence.

Common Traps

Trap 1: Using To After Enjoy

Say "I enjoy reading," not "I enjoy to read." The verb enjoy wants an activity, and English packages that activity as a gerund.

Trap 2: Using -ing After Want

Say "I want to sleep," not "I want sleeping." The verb want points to a goal or desired action, so it takes the infinitive.

Trap 3: Forgetting Prepositions

"I am interested to learn" can sound possible in some contexts, but the normal pattern is "interested in learning." The preposition in pulls the next verb into -ing.

Trap 4: Thinking Every -ing Word Is the Same

"I am swimming" uses -ing as part of a verb tense. "I enjoy swimming" uses swimming as a gerund, more like a noun. The shape is the same, but the job is different.

Trap 5: Missing Meaning Changes

"Remember doing" and "remember to do" are not twins. "I remembered locking the door" means I have a memory of the action. "I remembered to lock the door" means I did the task because I did not forget.

Trap 6: Trying to Memorize Too Much at Once

A giant list of verbs is easy to forget. A small personal list is more useful. Start with the verbs you actually use every day: want to, need to, decide to, enjoy -ing, avoid -ing, finish -ing, good at -ing, interested in -ing. When those become automatic, add the next group. Grammar sticks better when it attaches to sentences you really say.

Wrong / Better / Why

Mini Practice

Choose the best form.

1. I avoid _____ emails when I am angry. (send / sending / to send)
2. She plans _____ a new course this summer. (take / taking / to take)

Answer Key

1. sending - Avoid takes a gerund.
2. to take - Plan takes an infinitive.
3. extending - After about, use a gerund.
4. to arrive - Promise takes an infinitive.
5. waiting - Mind takes a gerund.
6. to turn off - This means you did not forget the task.
7. writing - Finish takes a gerund.
8. drinking - This means you quit or paused the activity.

Tiny Summary

Gerunds are -ing forms used like nouns.

Infinitives are to + base verb.

The first verb often decides the next verb shape.

After prepositions, use gerunds.

When both forms are possible, check whether the meaning changes.
