I've written a few phrases in Portuguese but doubt whether they are correct or not. I'd be grateful to get some comments.
Hello - Ola
How are you? Como esta? or Como vai?
Qual é o seu nome? - What is your name?
o que você pode fazer? - What can you do?
mostrar corações - show hearts
Hope this helps.
All the sentences are correct. Some comments about it:
You can say "olá" (with accent) or "oi"
Como está? - You need to put the accent, because that word without accent means 'this' (esta) and the pronunciation is different with or without accent.
It's just a litlle thing, but I think it's important to say, so now you know that there are two very similar words.
