No, you should ask "Can you give me some advice?" or "Can you give me a piece of advice?".
Here's why:
-
Advice is uncountable: According to the reference, "Advice is uncountable". This means you can't use the indefinite article "an" directly before it.
-
Correct Usage:
- Instead of "an advice," you should use "a piece of advice."
- "Some advice" is also grammatically correct.
Here's an example of offering advice:
If I were you, I'd wait.
