BASIC WORDS IN PORTUGUESE #1

(Hello / Hi) 
This is the basic way to start a conversation in Portuguese. 
"Olá" sounds more formal than "Oi".

(Good morning!) 
Brazilians are very sociable, saying "Bom dia" when you go into a room it's really common and polite.

(Good afternoon!) 
For me, it's only afternoon after I have lunch.  So, then, you can say "Boa tarde" to me.

(Good night/evening!) 
You can use this for both night or evening. Say it when you get to a new place and when you leave there too.

(Is everything good?)
Tudo = everything 
bem = good
This is an informal way to say "How are you?". 
Everyone uses it.
Feel free to introduce yourself saying: "Oi, tudo bem?".

(How are you?) 
como = how
você = you
está = is/are 
In spoken Portuguese, you may hear just : "Como você tá?"

(I am good. / I'm good.)

estou = (I) am
bem = good
"Eu tô bem" and "Tô bem" are used in spoken portuguese and in informal conversations.
