What does Tu querto mean?

"Tu querto" is not a correct Spanish phrase. It seems you might be trying to say "Tú quieres" which means "You want".

Here's why:

* "Tu" is the informal form of "you" and should be written with an accent mark as "Tú".

* "Querto" is not a Spanish word. The correct verb for "want" is "quieres".

So, to correctly say "You want" in Spanish, you would say "Tú quieres".
