Olá Amigo! (Hello friend!)

When you want to greet your friends and colleages in informal situation, you just say Olá followed by the name.

However, in formal settings, you can use either Bom dia, Boa tarde, or Boa noite followed by the name with title such as Professor + male name, Professora + female name, Doutor + male name, Doutora + female name).

There is a slight difference in the pronunciation of final syllables of the word tarde and noite between Portuguese of Portugal and Brazil. In Portuguese of Portugal, the final syllable tends to be silent and unstressed. However, don’t worry about the difference. Just speak and people in Portugal are happy to see you willing to learn Portuguese language. The most important thing is you greet them and smile!

Até já!!
