a piece of advice or an advice?
Hi to everyone! Who can explain to me what is the difference between a piece of advice and an advice? When have I to say "a piece of"?

Question

Answer

"An advice" is incorrect because "advice," when used as a single word, is uncountable. It's correct to say "some advice" or "a piece of advice" or "a bit of advice" or "a lot of advice" or "not much advice" etc.

Answer

"An advice" is wrong since "advice" is a concept (and thus uncountable).
