How do you say goodbye friend in brazilian?

Answer 1

The informal way to say goodbye would be "tchau" (pronounced t'-sha-oo). The formal way, the direct equivalent to farewell, would be "adeus" (ah-d'eh-oos).

We don't usually add "friend" at the end, but when we do we would say "meu amigo" (m'eh-oo ah-me-goo) if the friend is male and "minha amiga" (me-nha ah-me-gah) if the friend is female.

Answer 2

Boa noite me amigo. ("minha amiga" if referring to a girl, "meus amigos" if referring to a group with at least one male, and "minhas amigas" if referring to a group of only girls).
