I think it is Spanish but I agree the two languages are the most useful today.

There's only one way: our way.

Of couse if you already speak Portuguese you don't need to learn so you need speak some other language to need to learn Portuguese.

Você também é Brasileiro?

english because i speak it. and im sure the same answer goes for everyone else and what language they speak. there aint no best language

Sim, paulista .

Tem vários brasileiros aqui no fórum, existe inclusive um tópico apenas para nós mas eu perdi o link e a ferramente de pesquisa é um desastre rssssss.

Portuguese's grammatical rules are a pain in the ass indeed.

For example the English is so so so easy to learn because is simple. We have over eight tenses for verbs and the English have just three.

You know, I don't speak Icelandic, I may have misunderstood. xP

For me :
1) English ( Since mostly 60% of the world population know how to spoke english )
2) Japanese
3) Chinese

Que irado! Eu não imaginava havia tantos brasileiros por aqui. Se achar o tópico, me passa ele. =)
