"Eu preciso de um bom conselho."

Translation: I need some good advice.

[bwimer09]

"I need a good advice" is not a correct English translation.

[Davu]

Right. Advice is uncountable in English and so you can't have "an advice" (you can have "a piece of advice" though). The translation I see is "I need some good advice" which is fine, perhaps "I need a piece of good advice" works too.

[e.cambourn]

"Advice is uncountable" is it in Portuguese too? It seems like it is different to English.

[dogrow]

You are right, it is different, in Portuguese it is countable, you can say "Ele me deu dois conselhos sobre filhos".

"I need a good counsel" is accepted but shouldn't be. "I need good counsel" is not accepted but should be.

Wouldn't "I need a good tip." be possible? It was not accepted but I believe the translation would be closer to the Portuguese sentence...

[Paulenrique]

tip = dica

[DanishPastry3]

bom conselho vs. conselho bom?????

[AyrtonSmith]

so far, it seems (according to duo) that português accepts both forms. But I've also seen cases where the phrase changes when they're placed differently

[Cactopu5]

I need a good suggestion?
