Why is it not 'A sua chave' please?

[Paulenrique]

It's also right.

[Ricardo.orjuela6]

But I have a question, I wrote "Seu chave" and it hasn't been correct. is it correct or not? Thanks.

[Paulenrique]

It's not correct. "Chave" is a feminine noun, so you should use "sua".

[DraKovcs330405]

Seu is in case of words with artikel "o".

[Spam179946]

It is not correct

[RigoAsenci]

Could I have written Tua chave and been correct?

[Paulenrique]

Yes, it is also right.
