"Are they all the same?"

Translation: Eles são todos iguais?

[Libor]

is not it 'tudos'?

[Paulenrique]

No. tudo is neutral. todos means "all/every" for masculine words. Eles todos / Elas todas. ELES são TODOS iguais.

[harkrank]

Os tudos deles sao mesmos - why is this wrong?

[Paulenrique]

that just does not make sense in Portuguese. Maybe "eles são todos os mesmos?"

[JuliaGodin]

Is "eles" only used in this sentence when talking about people or would it be the same for instance for chairs?

[Paulenrique]

You use eles/elas for objects in plural too. As cadeiras are feminine, use elas.

[MelancholicChen]

"eles são todos mesmos/idênticos"?

Thanks. 08/03/2017

[Paulenrique]

"idênticos" works.

Or you can use "Eles são todos os mesmos".

[MelancholicChen]

@Paulenrique, why you add "os" before "mesmos"? Why don't "idêntico" and "igual" need "os" before them? You are considering all the three words as adjectives or nouns?

Thanks. 08/03/2017

[Paulenrique]

Because "iguais" and "idênticos" work as adjectives here, but it is not the case for the word "mesmos", so you need to add "os".

[MelancholicChen]

@Paulenrique, "mesmo" can be used as a noun, an adverb and an adjective: https://en.wiktionary.org/wiki/mesmo. I was using "mesmo" as an adjective as well. Why can't "mesmos" be used without "os" in here?

Thank you. 08/03/2017

[Paulenrique]

The point is that I think you'll always use a definite article with the word mesmos:

• Eles são os mesmos rapazes.
• Eles são os mesmos.

[G.Versao]

Porque "são" é não "estão"

[Paulenrique]

As we have no context, both "são" and "estão" should be accepted.
