Some verbs need to be followed by an infinitive (to + verb), and some need to be followed by a gerund (verb + ing).
In some cases, only one of these options is possible. However, sometimes both can be used and the meaning can remain the same, and sometimes it can change depending on our choice.
Can you see the difference in meaning in the examples below?
I was going home, but I stopped to smoke. After I finished my cigarette, I continued my commute.
I stopped smoking 5 years ago. Since then, I've become a much healthier person.
In the fist example, the person stopped the first action, and then smoked. In the second one, the person quit smoking.
We use infinitives in the following cases:
When we want to describe an action
Example: It's dangerous to ride a bike when it's raining. You can slip!
To express purpose
I'm saving money to buy a car.
As the subject of a sentence
To do the right thing is not always easy.
