"How many books do you have?"
Translation:Quot libros habes?
Sorry, but it is the main way of saying "so-and-so has X", and is the "Dative of Possession" (http://dcc.dickinson.edu/grammar/latin/dative-possession)
Not that I knew what Basicpract explained, but just because a construction in one language is very different in the literal translation to another language, that doesn't mean it isn't the closest thing pragmatically. So thank you for letting us know, Basicpract!
