hi Gabriel, "we" is a subject personal pronoun and "us" is an object personal pronoun and this is basically the difference between them

Thank's guuuys ! =D

Here are some simple but common ways to use "we" and "us": Are you coming with us to the movies? He isn't coming with us. We will meet him there. They keep in touch with us on skype. We know them very well. We love them! Do you want to stay with us? We have a spare room. Will you meet us at the airport? We arrive at.... in the morning. We are going there next month! All of us, including the children. I'm planning for us to visit a few places that we haven't been to before. Hope that helps!

Hi, Gabriel, I see that you are Brazilian so I will use a some examples in Portuguese: "Nós queremos ir para a praia" - "We want to go the beach" "Ele falou que sim, mas nós dissemos que não" - "He said yes, but we said no" "Ela deu dinheiro para nós" - "She gave money for us" "Quem quer ir comigo? A gente!" - "Who wants to go? Us!" "Ninguém liga para a gente" - "Nobody cares about us" Did you spot the difference? "We" is used more often as the subject who did the actio, while "us" is more like the object that suffered the action.

"We" is the subject of a sentence. Here is an example: We go to the park for a picnic. "Us" will never be the subject of the sentence.. Here is an example : She brought the picnic for us. Hope this helps!
