Learn each verb with its pattern. Spend a few extra minutes on the meaning pairs below, because the final check asks you to distinguish them.

By the end of this lesson, you can…

UnderstandRecognise common verb + -ing and verb + infinitive patterns.
ChooseUse infinitives after adjectives, purposes and selected objects.
UseExplain meaning changes after stop, remember, try and regret.

The essential rules

Verb + -ing

Common verbs include enjoy, avoid, finish, suggest, mind and consider. When a preposition is followed directly by a verb, use its -ing form.

She avoids driving. · Thank you for helping.

Verb + to-infinitive

Common verbs include decide, hope, plan, promise, refuse and want. Use it to express purpose.

We decided to wait. · I called to confirm.

Object and bare infinitive

Some verbs take object + to-infinitive. Modals and let/make normally take the bare infinitive.

They asked me to stay. · You must leave. · Let him speak.

Stopping an activity is different from stopping for a purpose

A habit ends
a coffee-drinking habitI stopped drinking coffee.that habit ended

The -ing activity is what I stopped.

A pause serves another action
another activityI stopped to drink.drinking is the purpose of the pause

The sentence does not name the first activity or guarantee that I resumed it.

Look at what stopped: drinking itself, or something else so that I could drink. The word drink alone does not tell us whether the drink was coffee.

When the pattern changes the meaning

VerbTo + base-ing
rememberRemember to lock it: do not forget the action still to do.I remember locking it: I recall the past action.
tryI tried to open it: I made an effort, perhaps unsuccessfully.Try restarting it: test this possible solution.
stopI stopped to drink: I paused another activity in order to drink.I stopped drinking coffee: I ended that activity or habit.
regretWe regret to inform you: a formal way to introduce bad news now.I regret sending it: I feel sorry about a past action.
The fully blonde adult reference sits at a refined office desk after an unsuccessful attempt to open a file on her laptop. She gestures calmly to its unchanged, indistinct screen while a colleague listens. Convey effort without the desired result, with a natural disappointed expression, not an error message or a successful opening.
I tried to open the file, but nothing happened.Try + to-infinitive describes an attempted action that did not succeed here.

See the pattern

PatternTypical verbsExample
verb + -ingenjoy, avoid, finish, suggestThey suggested taking a taxi.
verb + to + basehope, decide, agree, learnShe agreed to help.
verb + object + to + baseask, tell, encourage, allowHe reminded me to call.
modal + basecan, should, must, mightYou should check.
Teacher tip: Record a new verb together with its pattern: write avoid doing, not simply avoid. This turns grammar into retrievable vocabulary.

Three mistakes to avoid

✕ I suggested to leave.
✓ I suggested leaving.
Suggest takes -ing.
✕ She made me to apologise.
✓ She made me apologise.
Use a bare infinitive after active make + object.
✕ I look forward to meet you.
✓ I look forward to meeting you.
Here to is a preposition.

Guided practice

Try each item before opening the answer.

1. Complete: He promised ___ (call) after work.

to call: promise takes the to-infinitive.

2. Complete: Would you mind ___ (open) the window?

opening: mind takes -ing.

3. Explain: I stopped smoking.

I ended the habit of smoking.

4. Explain: I stopped to smoke.

I stopped another activity in order to smoke.

The same fully blonde adult reference follows a colleague’s suggestion to restart her laptop as an experiment. She presses its power key with a natural hand position, a dark screen and a colleague observing thoughtfully. Convey testing this possible solution, not guaranteeing that it will work.
Try restarting the laptop.Try + -ing proposes an experiment to see whether it helps.
