"O cachorro come tuas frutas."

Translation: The dog eats your fruit.

[Suyai1]

Here they said "tuas frutas" as plural, how can be the translation singular? your fruit...

[Danmoller]

"Fruit" is uncountable in English.

Although "fruits" exist, it's only used when you really want to express you're talking about "different types of fruit".

[Adam818197]

Cant "your fruit" in English be either singular or plural? The plural of fruit is fruit right?

[serg07]

Is "O cachorro come as tuas frutas." correct? Or do I have to leave out the "as"?

[Paulenrique]

you can include "as"

[PhillipStanley]

What's the rule on that? Is it optional? Or is it sometimes required?

[Danmoller]

Before possessive adjetives (with a following noun), using the article it's optional in Brazil (but preferred in Portugual)

Notice that when there is no following noun, you can change the meaning:

• São meus = They belong to me = They are mine
• São os meus = (hard to translate exactly) they are the ones that belong to me

What is the rule for when to use tua or sua?

[ViktoriaDeWit]

I think tua is more informal than sua and is only used with Tu and not Voce, which I think i dialectical. Tu is only used in certain regions, like mostly in the south of Brazil. But I not actually from Brazil, so don't take it from me!

[Danmoller]

Although "tu" might be regionalized, its related pronouns (teu, te, ti, etc.) are omnipresent.

In Brazil, there isn't really a distinction between formal and informal.

Of course there is a trend of using "tu + conjugation for você" - now this is informal of course. It's wrong but very common.

[PhillipBro6]

Tua/ teu is specifically your

Tua fruta - Your fruit

On the other hand...

Sua fruit - Your fruit. His fruit. Her fruit. Its fruit. Their fruit

It's a matter of context, although in Brazil seu/ sua is commonly used for your.
