Gerund and Infinitive: Extended Usage (Stop Doing vs. Stop to Do, Remember Doing vs. Remember to Do)

After some verbs, -ing versus infinitive changes the meaning.

Stop

• stop doing — quit an activity: I stopped smoking.
• stop to do — pause in order to do something: I stopped to smoke. (a cigarette break)

Remember / forget

• remember to do — not forget a future duty: Remember to lock the door.
• remember doing — remember that it happened: I remember locking the door.

Similarly regret to tell (I am sorry I must say) vs regret doing (I wish I had not done it). try to = attempt; try doing = test a method.

Fixed: enjoy, mind, finish, keep, avoid + -ing. want, hope, decide, promise, refuse + to.
