Переклад - Португальська-Англійська - Bom dia tudo bem com as manas

Oi diego

This looks good, the English is fine, but I'll have to poll, because I don't speak Portuguese.

"Everything is ok with the sisters". There's no question mark, so it's not a question (maybe it's lacking a question mark, but still, the sentence is supposed to be translated as it is).

Well... it's also possible a correct sentence without a question mark, but it's quite unusual in this case. When the person who's written that decided to use this slang 'mana' I can barely trust it's not a question.
Anyway I'll include a note commenting that.

"Mana" is not a slang for me at all, it is an intimate way to call is someone's sister. It is very used here in the south of Brazil.

And also southest.
Anyway if u don't consider that it's a slang u shall, at least, consider that is regional expression and so that the same linguistic phenomenom, that I told ya before, happens.

"mana" não pode ser considerado slang, senão uma forma coloquial de se dirigir a uma irmã, ou se referir a ela.
Tem o seu correspondente no inglês americano: sis.

Tantine: is the plural form for "sis" (sister in American colloquial),: "sises" ???

Oi Lilly, Oi Diego (May I call you by your first name?)

You have set me a real poser here!! I had to go and look in my English dictionary (which was of no help at all).

What I am going to explain here is not a grammatical rule or anything, so it is open to debate and maybe another English expert (or native speaker) could give you an "official" answer. Phew!!

For me the plural of "Sis" (pet abbreviation for "Sister" could not be "Sises" (it would be pronounced the same as "sizes" and would create confusion). If the the final "s" is doubled in order to render the word plural - "sisses", this would be pronounced in the same manner as "cissies" (effeminate persons) and would also create confusion.

How would I say it? That is the question!! I have 6 sisters, so I must often refer to them as a group. Erm, when I refer to them individually I say "My big Sis", or "My little Sis", but as a group I almost always revert to "sisters".

I'm sorry, I'm not being of much help!!

Maybe we could ask kafetzou? Seeing as you have added the note under the translation, I think we can validate this one.

Thanks everyone
