"She has two thousand books."
Translation:Ela tem dois mil livros.
It is the use of the verb querer. "You want a million OF what?" "Quero dois milhões de amigos", and "tenho dois milhões de livros". Davu had posted a very interesting point, but he deleted :( he posted, as you have received on your email, that it's necessary to use DE after million, billion, etc.
I should probably know this by now but can "estar com" and "ter" be used interchangeably?
e.g. Ela está com dois mil livros. = Ela tem dois mil livros.
