At all
At all means ‘in any way’. We use it with questions and negatives to add emphasis, but not with affirmative statements:
- Do you want to swim in the sea at all?
- She was not at all frightened.
We can use at all before or after an adjective:
- Were you at all upset by Kevin’s behaviour?
- They weren’t interested at all.
At all and politeness
We often use at all at the end of a question to make the question sound more polite:
- [ID is an abbreviation of ‘identification’]
- Do you have any ID at all?
- [a waiter in a restaurant]
- Would you like any desserts at all?
We can use not at all as a polite response to questions asking Would you mind …? or Do you mind …? and as a polite follow-up response to thank you:
- A: Would you mind taking this parcel to the main office?
- B: No, not at all.
- A: Do you mind if I sit here?
- B: Not at all.
- A: That’s very kind of you, thank you.
- B: Not at all.
