What you'll learn
By the end of this lesson, you'll be able to use the verbs whose meaning changes with -ing or the infinitive.
When do I use it?
These verbs change their meaning depending on the pattern that follows:
- remember to do — not forget the task: "Remember to lock the door." / remember doing — recall a past action: "I remember locking the door."
- forget to do — not do the task: "I forgot to call." / forget doing — no memory of it: "I'll never forget meeting her."
- stop to do — pause one action in order to do another: "He stopped to rest." / stop doing — finish the action: "He stopped smoking."
- try to do — make an effort: "I tried to open it." / try doing — experiment: "Try restarting the router."
- regret to do — sorry to say: "We regret to inform you..." / regret doing — wish you hadn't: "I regret saying that."
How do I form it?
verb + to + verb → different meaning from verb + -ing
- I stopped to buy coffee. (I paused the journey to buy coffee)
- I stopped buying coffee. (I no longer buy coffee)
- She remembered to take her keys. (she didn't forget)
- She remembered taking her keys. (she can recall doing it)
Common mistakes for Spanish speakers
Spanish distinguishes these with different verbs ("acordarse de", "olvidarse de", "dejar de"), but the two-pattern trick in English is easy to flatten: "stop to smoke" (pause to smoke) and "stop smoking" (quit) get mixed up. With "remember", "me acuerdo de cerrar la puerta" could be either — in English the -ing form says you recall doing it, the infinitive says you must not forget to do it. Pick the pattern that matches the meaning.
Infinitive = future/effort (a task to do). -ing = memory/experience of doing something.
