IS 'STOP' FOLLOWED BY THE INFINITIVE OR BY THE GERUND?

 In English 'Stop' is normally followed by a gerund. When we stop doing something it means the verb in the gerund is the thing that we ceased to do. It can mean 'stop forever' or 'stop at that moment':
- My mum came home so I stopped playing on my PS4.
- I stopped smoking for health reasons.
- I had had plenty so I stopped drinking.

'Stop', more rarely, can be followed by an infinitive. In this case, we stop an activity in order to do what is indicated in the verb in the infinitive.
- I stopped to rest for a few minutes.
- He was shopping and she stopped to get a bite to eat.
