Learn Portuguese

Greeting. It is always polite if you can say hi in Portuguese. In the morning, you say BOM DIA, if it is afternoon it´s BOA TARDE and after the sun went down, you say BOA NOITE. If you forget about all of this, a simple OLÁ is also OK!
Goodbye. Just leaving without a word is a bit rude. To keep it very simple just say: CIAO (as in Italian) or ADEUS (pronounced adé-oush)
Drinks. A beer is called UMA CERVEJA (pronounced servesha). Red wine is VINHO TINTO, white wine is VINHO BRANCO and then there's VINHO VERDE (sparkling very young wine, mostly white).
Thank. Men say OBRIGADO and women say OBRIGADA.
Politeness. If you want to ask something politely, you add POR FAVOR or FAZ FAVOR to the subject of your desire.
Pay. Time to ask for the bill: A CONTA SE FAZ FAVOR
Sorry. Desculpe! (Pronounced desh-koulp). If you just need a simple yes: SIM (pronounced sieng). No means NÃO (pronounced Now).
