Understanding the Core Difference
When we use remember/forget with a gerund (doing), we're talking about memories of past experiences. When we use them with an infinitive (to do), we're talking about future tasks or responsibilities.
Past Memories with Gerund (-ing)
Use remember/forget + gerund when recalling completed actions or experiences from the past. The memory comes AFTER the action happened.
Future Actions with Infinitive (to)
Use remember/forget + infinitive when talking about tasks that need to be done in the future. The remembering/forgetting comes BEFORE the action.
Examples
I remember meeting her at the conference last year.The meeting happened in the past, and now you have a memory of it
Don't forget to lock the door when you leave.The locking needs to happen in the future – it's a reminder for an upcoming action
She remembers visiting Paris as a child.The visit to Paris happened in the past – it's a memory
I remembered to send the email this morning.First came the remembering, then the action of sending the email
Common Mistakes to Avoid
❌ Incorrect: I remember to meet her at the conference.
✅ Correct: I remember meeting her at the conference.
Explanation: If it's a past memory, use gerund (-ing)
❌ Incorrect: Don't forget calling your mother.
✅ Correct: Don't forget to call your mother.
Explanation: For future tasks or reminders, use infinitive (to)
❌ Incorrect: She remembers to visit Paris as a child.
✅ Correct: She remembers visiting Paris as a child.
Explanation: For past experiences we recall, use gerund (-ing)
Tips for Success
- Think 'memory = -ing' for past experiences
- Think 'reminder = to' for future tasks
- Ask yourself: Am I recalling a past experience or planning a future action?
- If you can add 'last week/year' it's probably a gerund
- If you can add 'later/tomorrow' it's probably an infinitive
