번역 - 포르투갈어-라틴어 - Seremos para sempre amigas, sim, se ...

It's quite good translation. I have only few remarks:

for ever --> in perpetuum

indeed --> vero

and: "amicae" is verbum femininum. Maybe you should translate in masculinum and the feminine version put into the remark field? What do you think about it? We (Efylove and I) usually do it in this way in such cases... but you can do it in the opposite of course to be kind for women...

OK for both "in perpetuum" and "vero".

I think it's unnecessary to translate into the masculine form and relegate the feminine one to the remarks, because the Brazilian Portuguese is in the feminine. As English doesn't distinguish between male and female friends (), I had to make it clear under my bridge (just where the river flows...)

Unfortunately I don't know Portuguese, but I am permanently learning it with you all here... Thank you for your explanation.

Oh, I will suggest to change also an order a bit to make the sentence more understandable:

erimus vero amicae in perpetuum.
--> amicae in perpetuum vero erimus.

Do you agree?

Oh, yes. The wording here is a bit complicated because in Portuguese the lexical parts are in inverted order.

Accepted!
